3DArtZ Posted January 2, 2013 Share Posted January 2, 2013 Hey guys, been a long time since I've posted anything.... still working on that audi model.... Or I should say still not working on it!!! lol. But had an itching to mess around with some displacement maps. Simple torso model with a displacement map and then used again as a diffuse map. 6minAbs.mov Mike Fitz www.3dartz.com Quote Link to comment Share on other sites More sharing options...

MMZ_TimeLord Posted January 2, 2013 Share Posted January 2, 2013 Question: What is the render hit vs. a simple bump map? Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted January 3, 2013 Hash Fellow Share Posted January 3, 2013 Question: What is the render hit vs. a simple bump map? the big hit is that you have to use multi-pass to use displacement maps In a test case (where the object covers about 50% of the image) a bump-mapped model takes 44 secs to render in 16 passes while a Displacement-mapped model takes 64 seconds which is not much more. But the bump mapped model can render with the same anti-aliasing quality in a non-multipass render in 7 seconds. If you drop the Displacement render down to 2 passes it will come in about the same as the regular render bump map case. Quote Link to comment Share on other sites More sharing options...
MMZ_TimeLord Posted January 3, 2013 Share Posted January 3, 2013 Thank you for that rapid response. If rendering finals for production, I would probably use it then as the hit is only about 30%. That would of course depend upon the scene, amount in frame, etc. Typically, you would not have a huge amount in frame unless you were flying in for a closeup of a bee sting or some such.

3DArtZ Posted January 3, 2013 Author Share Posted January 3, 2013 Question: What is the render hit vs. a simple bump map? yeah... what robcat said... this vid didnt use multipass.

Hash Fellow robcat2075 Posted January 3, 2013 Hash Fellow Share Posted January 3, 2013 Holy S### I have an old v14 beta that I can run with my v13 disk and yes, displacement mapping does work in regular render. Why didn't someone say this earlier! I think Martin told me once that it had to be done with multi-pass. Quote Link to comment Share on other sites More sharing options...

Gerry Posted January 4, 2013 Share Posted January 4, 2013 Great tests Mike! You know you can also animate the strength of the displacement map with a smartskin, which raises a whole separate set of possibilities. Quote Link to comment Share on other sites More sharing options...
Xtaz Posted January 4, 2013 Share Posted January 4, 2013 This is a really cool tests Mike. Just a little detail, the abdomen muscles are convex, not concave, as they appear in your test. Can you show us the displacement map ? Quote Link to comment Share on other sites More sharing options...
3DArtZ Posted January 4, 2013 Author Share Posted January 4, 2013 hey guys, thanks for the comments. Xtaz, the convex you mention is the actual model itself, not from the map. I built is sloppy and fast. I'll see about getting the map up for people to look at. Gerry, I know I have not been around for awhile... but you know I expressions and driving decal strength!!! lol.

I drawed a gradient color in the displacement map and the result seems better. Quote Link to comment Share on other sites More sharing options...
3DArtZ Posted January 4, 2013 Author Share Posted January 4, 2013 Cool Xtaz! Results are def. better as the gradient or softer transitions between the light and dark translate to the surface elevations. If I can get motivated enough to do more on this I will certainly make better maps. I loaded your edited map and it looks very cool! will post a moooovie.

John Bigboote Posted January 5, 2013 Share Posted January 5, 2013 A trick to try if you want a better resolution and smoother displacement(looking at Xtaz's close-up image) would be to open the art in Photoshop and enlarge the image size about 4X and then run a guassion blur on it to smooth the pixillation and resave...

Gerry Posted January 5, 2013 Share Posted January 5, 2013 Definitely the trick with disp maps is to keep the gradient area as smooth and gradual as possible. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted January 5, 2013 Hash Fellow Share Posted January 5, 2013 also... if you are getting stair stepping from the 8-bit maps, OpenEXR maps work too. Harder to find a paint program for them however. Quote Link to comment Share on other sites More sharing options...
itsjustme Posted January 5, 2013 Share Posted January 5, 2013 also... if you are getting stair stepping from the 8-bit maps, OpenEXR maps work too. Harder to find a paint program for them however. Krita can handle OpenEXR images in either the Mac or Linux versions (the Windows version doesn't presently). For someone on Windows, you could install a version of Linux on a thumb drive and run it from there. Quote Link to comment Share on other sites More sharing options...

itsjustme Posted January 9, 2013 Share Posted January 9, 2013 I haven't checked the Windows version of Krita yet, but I did an experiment with installing Linux Mint on a 16GB thumb drive. I installed and ran Krita as well as Kdenlive and Cinelerra...all worked fine. I would recommend using a USB3 drive though. I'll have to do a lot of playing with the programs, but it was a very promising test. The combination allowed me to create and edit OpenEXR images and edit HD video...would definitely help with my project. I made a quick OpenEXR image, saved it to a Windows format thumb drive (I could have saved it to the main drive, but I was being careful the first time), booted Windows and used it as a decal in A:M. So, I should be able to go from one OS to the other pretty easily. Quote Link to comment Share on other sites More sharing options...
