Thanks for posting, psycholis. This is my favorite type of feedback. :)
It’s a bit surprising to me why so few ppl are into 3D. Great to see another of us.

20 years ago I thought that one day when computers became accessible to everyone most persons would want to use these new tools to their fullest, be it 2D, 3D, programming, audio, video, and so on, but nowadays it seems most are happy watching porn and cat videos, and updating their facebook page.

My initial plan was to keep updating this thread with the several stages that each room would take, almost like a “making of”, but laziness got in the way. I’ll try to do this with Dizzy49’s room. Tomorrow I’ll try to organize things and post.

As I said in the post above, instead of just posting the final renders I’ll place below some images of the different steps of the building process of one of the latest rooms I built, from the basic layout to the renderings. This first example is an office, Dizzy49 asked me to model his (future) office and theater, his main goal was to test a few color schemes to help him decide what better fits these two rooms. You can follow his build thread here:
http://www.avsforum.com/forum/19-dedicated-theater-design-construction/1734906-halls-justice-build-thread.html

Modeling the cabinets and other objects
The office will have a lot of cabinets, and it was important to make sure their 3d recreation was accurate. Building them was a time consuming process, they don’t exist yet so I had to follow some images and dimensions provided by the maker, but with a lot of patience Dizzy49 cleared all my doubts. Initially he planned to have the cabinets totally black, but I managed to lobby him into using a lighter color for the countertop. :)





One of the other big objects I modeled was an AC air handler, Dizzy49 wanted to place his wedding picture on the handler’s frame. The photo is priceless so I had to do it. :)

Besides the dimensions, I'd need as much detail as possible regarding the layout and furniture's placement, speakers (also of their type and size), screen format and size, colors, and everything else that is considered important, in a clear explanation. Having 2D drawings would be a nice plus, but I guess not everyone has them.

Actually, thinking about it and how my home-theater project evolved, it’d be nice to know the main doubts (if any) that the person has regarding the room: “I’m trying to find out if a 2.35 screen would look good so near the walls”, or “if a 2nd row of seats is visually pleasing”, or “if this color scheme is pleasant looking”, this way I could focus more in certain points.

My time is limited, so the best method to make this is probably to build a simple model as a start, basically just the walls and main features, and from there through PM or mail I'd change and add details according to the person's feedback.

You could do a real service to the whole AVS community related to making Dolby Atmos speaker placement more clear.
I posted the below in the Dolby Atmos HT thread ( 09-17-2014), not realizing that we had a SME here on sketch-up.

Most people have trouble visualizing the placement of their speakers to the new Dolby guidelines.
Having a generic 3D model that they could then take and tweak to their specific HT set-up would greatly help.

Dolby has released their specs here, http://www.dolby.com/us/en/technologies/dolby-atmos/dolby-atmos-home-theater-installation-guidelines.pdf

Are you the "AVS person that can step up" that I was looking for? :D

http://www.avsforum.com/forum/90-receivers-amps-processors/1574386-official-dolby-atmos-thread-home-theater-version-276.html#post27489570
Issue;

  • Confusion on various layouts Dolby Atmos can accommodate in home setting
  • Lot's of same questions get asked again-again, text based, answers given, rinse-and-repeat for very similar situation
Proposal:

  1. The Dolby Atmos full 24.x.10 layout guide be put into 3D space so all can more easily grasp the maximum benefits to their either dedicated HT layout or multi-purpose room layout.
  2. Use free Google SketchUp. Yes I did a search and to what I found there is no Dolby Atmos generic model in 3D cad, http://www.sketchup.com/
  3. The full 24.x.10 be put onto SketchUp for 3 row "large" home theater space, with corresponding angles/et all clearly marked (Large space being say 18 ft wide x 28 ft long x 12 ft high, just over 6,000 ft^3)
  4. Cross correlate that to Auro-3D (and DTS-UHD later) by some color scheme to show compatibility between systems visually
  5. Inside that "large" home theater space, add 2 row home theater walls to show how the 24.x.10 would be mapped onto room of less size/volume; baseline 2 row would be 15 ft wide x 20 ft long x 9 ft high 2,700 ft^3. Having speaker to MLP vectors should show the intersection positions onto 2 row.
  6. Save these files as templates on the sketch up server, for all community can easily access them, https://3dwarehouse.sketchup.com/search.html?q=home+theater&backendClass=entity
  7. It's much easier to modify a 3D drwg than create one, so this will open up for many members to do their own Atmos study, post that here for more effective peer reviews.
Background:
After reading this thread on/off I had considered doing this 3-4 days ago, and actually started doing it myself and quickly realized I'm too busy with life/scouts/soccer dad/RH hip surgery upcoming. I'm an old tool designer draftsman from 1978-1983, and upon moving thru Engineering school and management my CAD creation days are beyond me, but to modify/tweak existing template is easy.

Therefore......Which AVS person can step up?

Markus post below triggered me to write this post, after all this is the "all things Atmos, both now and future", so why not have a generic 3D CAD model for all to use/grasp?

Dolby's recommendation is quite ambiguous. They define ranges but no preferred locations. This is what their 9.1 graph looks like when you draw in the recommended angles:

My earlier post on attempting to get a visual added to first post....it would be really nice also to have a FAQ .......

Wow - this thread sure has exploded and what not.
Marcus, can you add graphic visuals that explain Atmos to your 1st post?
Makes things easier to grasp.
I've added these to my "moving-past-7-1-into-9-1-11-x-3d-objectaudio" thread, not sure if there are other "better" ones, which are "official" Dolby issued vs AVR Manuals, etc.

Hi everybody. Just saw someone in the forum offer his help building 3D models, and thought I could do the same. So, if you´re interested in checking your future theater in 3D, perhaps I can help. I’ve been using Sketchup and other 3D software quite extensively for quite a few years, and this experience proved to be invaluable to plan my home theater, so maybe it’s also useful to others.

If it’s a complex project involving riser/columns/other details, and/or requires 3D rendering and lighting I’d need to charge something, but if it’s a simple Sketchup model with the basic room’s shape I’d be happy to build it, time permitting. Of course, the more info you can give, the better the final result. Please provide accurate dimensions, and a clear explanation of what you need.

If you want to see some of my 3D stuff you can check my theater build thread here, or scroll down, I’ll post a few examples.

what are you charging for this service?

Not sure if I can or should talk about values here, it’s probably better to contact me by PM. But at least for now if it’s something that I can make in 1 or 2 hours simply building the room’s basic shape for the person to see it in 3D, I’m charging nothing. If it requires more work, I’m asking for significantly less than what I’d ask for a “normal” 3D work, I’m doing this mostly for fun, but in any case these things take time and I’m saving for a new PC – rendering is very CPU intensive - so all extra funds are welcome.

Hi mtbdudex. This seems an interesting challenge, I can try to help. I’m not up to speed with this whole ATMOS thing besides knowing what it is and a few assorted readings, though, I’d need some guidance.

How useful would be to have a 3D model with the 24.x.10 layout? Wouldn't this confuse most persons, probably more interested in the lower number of speaker variants? And also, is there such a thing is a preferred location to every speaker?

By doing the 24.x.10 layout, you cover all the various speakers people can choose.
It will "future proof" the layout, as their are now AVR's that can only handle 7.x.4 or 9.x.2, but in 2015 that is expected to change.

Even now, the ceiling config people can pick/choose any of them, as long as they are not next to each other, that is limitation of current DSP chipset that will be updated in 2015 offerings.

I'll PM you.

we are taping off the walls this weekend - I'll take some measurements and send them to you. I have some mechanical issues with my ceiling that I will probably have you ignore for the purposes of this drawing.

Sure, take your time, the more info you can provide, the better. Door location, height, and so on.

Texturing
Always one of the most crucial things to get right, in this case the biggest challenge was the carpet. Dizzy49’s wanted to check the color schemes with a specific carpet, but the shop didn’t provide an image with the full pattern, only a small portion of it. The only available images were these two:





The solution in these cases is to try to extract the pattern with PS lens correction from the second image. Easier said than done, because despite being a hi-res photo it isn’t ideal, the pattern also isn’t complete on this image. A lot of trouble for a single texture, but Dizz49 was also planning to use the same carpet on his theater, so it'd be useful later to compare different color schemes there. With that in mind, a lot of patience and a few tricks it was finally possible to complete the pattern to get a usable carpet, and I could place it on the 3D model.

Rendering
Once all the modeling, texturing and lighting of the model is ready, the final step is to apply the right materials to the right surfaces and objects. In our real world each material has a different reflection level and characteristics, and without exhaustively go through almost all the 3D model and set those accurately the result will never be close to photo realistic.

An extra step I usually like to make is to enrich the model with smaller objects that may fit the scene. In this case I added books, screens, pencils, post-its, and a lot more. The big majority isn’t mine, but most had to be changed, be it geometry, textures, or applying materials, to render properly. Of course, this isn't necessary and most designers prefer to not stress about it, but with the room looking more realistic it's easier to make a better decision regarding the colors and layout.

The final scene, ready to render.


Final render


Dizzy49 will probably post the full set of renders on his build thread with all the color schemes we tested, but if not I'll place them here in a couple days.
