STICKY: After the tone DIALux


I’m getting lots of traffic due to my DIALux article and I see a lot of search terms that include “DIALux” in them and there is certainly a lot of clicking on outbound links for DIALux but I haven’t heard back from any readers about what they are doing with DIALux, how it’s going, and what they think about DIALux. I’d really like to know, I’m genuinely interested to get some feedback (as I am sure DIALux would too) from you.

Come’on! Post a comment or send me an email and tell us whaaasssuppp! 8)

    I’ve had access to DIALux for a few years now but I’ve only really got stuck into it in the last 6 months. Partly because the firm I work for uses AGI32 for the bulk of our lighting calcs, and until I used DIALux for a lighting assignment there was no real need for me to use another program.

    The output at the end of the calculation would be the best thing going for DIALux which none of the other lighting packages that I’ve used seem to have. Once you have finished a design with DIALux you can print out a report at the end which is worth handing to client or including with other documentation. With AGI32 you have to try and use their page manager which isn’t terribly intuitive or export the design as a DXF and set up something in AutoCAD.

    One thing I have noticed is that DIALux does seem to accept more luminaires than AGI32 does, I often end up using DIALux when the IES data I have can’t be imported into AGI32. I’ve done this on a few in-house jobs, however I try to avoid it where I can since no one else knows how to use the software.

    Can you also let us know your thoughts on the program, if you use this as your main lighting design software, anything that could be improved, have you had any problems with it, etc? If we get a dialog started more people may provide their input.

    Thank you Michael for taking the time to post a comment. Interesting comparison against AGI32. I am not familiar with that program. I checked out their website and it seems that AGI32 does have a fair selection of powerful calculations as well as decent modeling and rendering capabilities. The interface seems a bit kludgey. The page manager looked really lame but I have said all this without actually trying the program. I intend to give the demo a whirl in the future. The biggest drawback I can see is that feature for feature DIALux is right there with AGI32 and is totally free and I suspect AGI32 is quite expensive. I went to request a quote from AGI32’s website and the form requested my name, my company name, and what product I wanted a quote for and nothing else. I clicked submit and it said my email has been sent to their sales department (or something like that) but I never gave them my email so either their quote for stole it off my PC which really makes me angry or they need to revamp their quote form. I would be really interested to know approximately how much AGI32 costs. Do you have any idea? In answer to your questions, unfortunately, I am not a lighting designer although I do have years of experience with light, light measurement, and lighting in general. So therefore, I do not use DIALux or any other lighting calculation program on a regular basis. I ran into DIALux purely by accident and was so impressed that such a powerful program for such a specialized purpose was so well executed and thoroughly free that I couldn’t resist. In the interests of my readers, I downloaded DIALux and gave it a test drive. It is a testament to the ease of the software that I was able to jump right in and create a working analysis model and report that makes sense. How much of my knowledge about light saved me, I don’t know. I suspect quite a bit but I also suspect that seasoned lighting designers/engineers will have no problems picking up this program and cranking out results. I wasn’t thrilled with DIALux when creating custom luminaires. It was confusing and not well planned. I can’t see why anybody would go with any other program as long as DIALux is available for free but then again, I haven’t had any experience with the competition so maybe I’ll run an article pitting some of these programs against each other. Hmmm…๐Ÿ˜‰

  3. Michael says:

    Well I’m not sure of the US price of AGI32 but a one year subscription to the program is roughly AU$1200 for us in Australia – similar to the subscription programs from Autodesk whereby you pay a yearly fee for technical support as well as updates whenever they are released. Which makes a program like DIALux a whole lot more attractive considering that it’s free. I am still yet to do a detailed comparison of the two programs, but from what I understand DIALux is one of the industry standard programs in Europe and we also have a few lighting suppliers here in Australia who use it without any issues.

    Costs aside, I am slightly more partial to the DIALux interface than the AGI32 one, and I’ve been using AGI32 for a good year longer than DIALux. Coming from an AutoCAD background both programs can be a little frustrating at times because you don’t have the same modelling capabilities, however can always draw up a model in AutoCAD and later import it into the lighting software.

    I have never needed to create custom fittings so can’t really comment on that aspect of DIALux, however I believe the people who created AGI32 also have another program called the Photometric Toolbox which I believe allows you to create your own luminaires. If I remember right it also lets you modify existing photometric data and convert it from one format to another. By the sounds of things this program (which is stand alone from AGI32) may be up your alley – it’s also a bit cheaper.

    A few other programs I’ve recently come across are Relux (http://www.relux.biz/) which I think is available as a free version. Calculux (www.lightingsoftware.philips.com/) which comes in a few different versions depending on the application. And ECOTECT (www.ecotect.com/) which is a architectural planning tool for energy efficiency, I haven’t had a proper look at this one yet, but I think the lighting component of the software is more focused on calculating daylight than artificial light.

  4. Kc says:

    We use DiaLUX mostly just to show a client what it might look like if they used certain fittings in a room. So we build the room and then put the fittings in and show their output. The only things I can comment on as regards the software due to how I use it is the imagery used. I find that printing the image comes out too pixelated and it is quite annoying that the people in the software are 2D (especially when everything else is 3D) and that you can’t have then sitting down or anything except standing. Other than this it is a very useful piece of kit.

  5. gita says:

    hai,,, im gita, i use dialux for 2 years. i think dialux is very helpful software. u can get the best rendering but in easy way,,, i like dialux because u can see the output, result of calculating just only by check what u need. and also dialux is a software to see a simulation of the lamp that we use. u can arrange the lamp just fill how much lux that u want, depends on the function of the room.

    if u want to learn dialux,, i’ll help u,, just email me,,,๐Ÿ™‚

    GC

    I agree, the omission of 3D people is a bit odd but one that can be overlooked based on the tremendously low price of free.๐Ÿ™‚ Has anyone looked into creating objects for import such as people? Does DIALux let you do that? I forgot. If it does, there are dozens of great places to get new 2D and 3D people out there.

    Thanks for the info and the offer gita! 8)

  8. Albirto says:

    Hi! I use Dialux from 1999 and I’ve seen its grown. I left all other calculation softwares (Oxitech, Relux,Photos) because Dialux is faster and very easy to use. It can manage complex indoor or outdoor projects, but the best thing is its “export to pov-ray” option. With it I can create real-like pictures, as you can see in this page

    Tecnoluce – Render

    • George says:

      hello Albirto, man those renders are phenomenal. Very impressed. We use Oxytech 10 (soon to be 4D) but our offices are thinking of making the jump to Dialux. I found your comment encouraging, thank you.

  9. Neil says:

    Hi all.
    Very interesting reading the comments here. I work for a company that uses Relux. I have used Relux for about 6 years now.They bring a new version out every year, but in my humble opinion they still have not really addressed the texturing and rendering issues. So at first look, Dialux is streets ahead. I am just starting to learn it but am unable to extract the manual after download. Could anyone possibly help me with this please?
    i have noticed that some people have put drawings on YouTube. Well worth a look.
    Happy New Year to all.
    Neil

  10. Ezzat says:

    DIALux is very powerful software and is improving very vast
    They Have gallery that show some design , Also they have video gallery that shows very nice video generated by the software
    It is supported by more than 80 companies all over the world including Europe Japan & china

  11. craigbic says:

    Thanks to Albirto, Neil, Ezzat and everyone else for the comments! Keep’em coming!

    Albirto, those are very nice renders! I like the output to Pov-Ray myself. I like keepin’ it all free even better!

    Neil, I will get you the manual if you still need it. Let me know.

  12. putra says:

    I’ve used Dialux at about 4 years. It usually impresses the client with its nice report and 3D rendering. Just need more furnitures included in the next version.

  13. jay says:

    Hi guys
    I tried this as i novice a few days ago
    brilliant easy to use
    are there any tutorials available

    thanks

  14. craigbic says:

    Thanks putra and jay! Nice to hear from you. I’m glad to see you like DIALux. I think it’s, pound for pound, one of the best, most useful and totally FREE programs available. Pity that there really isn’t any support community to build up a knowledge base around it. It will come in time. Maybe this blog will spearhead that initiative.

  15. Ezzat says:

    The following link shows a project done using DIALux 4.4 & Rendered with POV-Ray

  16. vinoth says:

    I’m new to dialux. Is it a free software. Is it possible for me to create a complete building using dialux, because i tried a lot with it, but i can do only a single room and not a complete building as Ezzat did. How to do it? Can anyone help me out??

  17. Albirto says:

    Hi Vinoth! You have to create an outdoor scene. With Dialux you can build simple geometries with its library of 3d models , but if you have a complex scene you ought create the 3ds with autocad then put them inside in Dialux.

  18. Duane says:

    I have been using lighting software for approximately 4 years now and have used a number of them. Agi32 and AGI-light, along with free vendors software. Due to recent events i am in the need of a free lighting software program. I am trying to learn Dialux and it is giving me fits. I have inserted a column in the design and it automatically places it at the origin rather than letting me place it where i need it. and removing it is impossible. also i cannot find where to set the units so that i can place the column exactly where it needs to be it is off by about 4 to 6 inches. i can also get the first fixture placed but i cannot copy it. Maybe it is just me but i am having trouble believing that this software is as easy to use as everyone says. An in depth tutorial is greatly needed for this software.

  19. Melvyn says:

    In it’s latest version 4.5 Dialux is able to impot *.3ds to be used as as the modelling base.
    I somehow got to try out AGI32; the modelling interface is totally different from each other. Being used to Dialux; it’s gonna be another learning curve on all the modelling techniques. The page manager is not that intuitive as compared to Dialux. But I like the customised interface; I believe with much tweeking; the standard template can be used for all your projects.

    I am hoping someone with more experience in using both AGI32 & Dialux can advice on the comparison. Other then Dialux is Free and has all if not most of the capability of AGI32 calculations.

    Cheers.

  20. Ezzat Baroudi says:

    Hi Melvyn
    Yes you are right, Actually I made I a comparison between DIALux & Relux On

  21. Mere says:

    I’ve recently begun using DIALux and had a couple questions:

    Does anyone know if there is a way to create curved streets or streets that go up and down hills?

    Also, has anyone created their own light files? I have found an IES standard for documenting the luminaire data, but I’m not sure how to bring it into, and/or render it in, DIALux.

  22. craigbic says:

    Mere, perhaps modeling the terrain along with the curved road in Sketchup might be the way to go? Sketchup has terrain tools for doing just that. Then you could import the 3D model back into DIALux?

  23. Mere says:

    Thanks. I found a way to import a 3ds file and can now create a more complicated street. Do you happen to know anything about creating custom light files and importing them into DIALux

  24. daithi says:

    Hi everyone great to see a dialux blog up here and i also would like to be involved, i use dialux at work and i am a young engineer so my experience is very limited on it but i think dialux is a fantastic package and is something that i would like to gain good skills at hopefully you all could help me on this

  25. Michael says:

    Hi everyone,
    i work with dialux a litttle time and i ‘ve searched for tutorials in the net but i cant find anything.I work as a lighting designer and i really like my work and dialux but my renderings are not good.I find povray difficult to manage for example to make beautiful reflections on a wall etc.Can anyone help me with some tutorials mostly interior projects rendered with povray?
    thank you guys.

    At http://forum.dialux.com/ there is now a forum for DIALux users available. Please check out this new forum.

    There you will find valuable tips and tricks, you can ask questions and you can chat about general things around DIALux.
    We as “the creators of DIALux” try to answer your questions, however a board lives particularly by the collective intelligence.
    Therefore our biggest desire:

    Register yourself and bring your experience and your DIALux knowledge into this board.

  27. Mere says:

    I know most people use DIALux to render architectural lighting scenes, but does anyone know anything about creating retro-reflective materals or exactly what the roughness factor (under Surfaces/Raytrace Options) is exactly?

  28. this dialux is new to me. Need to look into this asap

  29. Paul Tracey says:

    Renditioner

    There are a few extras that IMSI have produced of late that either help out specific TurboCAD users, such as furniture makers, or greatly improve other products with IMSI technology.

    One of these is the IDX Renditioner. It is a plug-in for Google SketchUp that provides high-quality photorealistic rendering โ€“ fast and easily. Renditioner works directly within SketchUp and lets you control the materials, advanced lighting components, environments, background images. Renditioner is โ€œone buttonโ€ easy with 3 render options of Preview, Standard and Presentation. It is simple enough for novices and yet powerful enough for professionals. Powerful features are optimized in a jargon free interface. Simplicity paired with speed and working directly in SketchUp, means you can achieve design visualization objectives more quickly. Renditioner offers 16 megapixel renderings for large-scale printing and powerful presentation of your designs.

    It is available for Windows XP or Vista on the PC, and OS/X 10.4 or 10.5 on the Mac and runs on either PowerPC or Intel-based Mac computers. As an extra it obviously requires you to already have SketchUp, but will be fine on the free version as well as the Pro version 6.4x or later. Like all photorealistic rendering, IDX Renditioner uses a system’s RAM and CPU power extensively, and is not recommended on systems with less than 1 GB RAM, with 2 GB recommended. Being fully multithreading, dual core, quad core, or dual quad core machines will each improve system performance dramatically.

    SketchUp is a nice piece of kit, but with the edition of Renditioner it jumps from good to professional, and then you import the SketchUp drawings into TurboCAD to add another dimension.

  31. Sanam says:

    can anyone just help me in collecting all the advantages of AGi32 over relux or/and dialux?

    does agi32 have a calculation procedure using the CIBSE or the BS as the platform?

  32. Max says:

    I have no experience with Dialux but I love to know.

  33. ugur says:

    Hi all,
    i read all of the comments, but i want to learn something about the lighting presentations. Coz i have some other problems for my thesis , is there a way to use dialux or relux files at 3dsmax/maya/rhino based 3d programs coz they have enough rendering systems. And if its possible whats the process?

  34. nightlord says:

    I am a lighting designer/contractor and have used dailux for a few of my contracts and it does offer pretty good rendering of most interiors – though not as close to rendering as 3d max.

    Most of the calculations are accurate as long as you keep in mind that there are some limitations like actual wall reflectance and to a point daylight ingress.

    My presentations are all based on visual renderings and work level isolux.

  35. In our field, architectural rendering and computer animation, we are always researching articles on the science of lighting. I will put this blog in our favorites.

    Thanks

    hi I’m khalid from libya and I’m a new user of dailux4.7 so I need some examples to learn more about it

    • craigbic says:

      Other than the examples I gave in my previous DIALux post WAYYYY back, I don’t have any examples. I have, unfortunately, not been able to touch the software in some time. I am sure the community at large has many examples and DIAL now has a DIALux forum for additional help/examples. Unfortunately, the forum is only available in English and German. Thank you for checking out the blog!๐Ÿ˜€

    A bit off topic, but has anyone tried the new Oxytech Lightstar 4D program yet? If so any feedback?

  39. Roxana says:

    Hi all,

    I just start to use Dialux and I got stocked at the first step – Importing an Acad dwg. I am using the AGI 32 and has been more than 4 years since I use this program on a day base. I can’t believe I just can’t figure out how to import my dwg in DIALUX. The user manual does not say anything about and I couldn’t find any tutorial about.
    I am using the Import command, loading my dwg but nothing shows up on my CAd window. Please let me know where/ what I am doing wrong!! Thank you

    • Kang says:

      Roxana, place your autocad drawing first into x=0, y=0, z=0 coordinates before u upload it to dialux. there maybe lots of drawings in ur CAD which u may not see. Zoom Extend it and u will see. cheer-u!
