So far, I've been able to attach to vrcompositor.exe with RenderDoc and intercept the D3D calls that do the composition. According to Baldur Karlsson (the author of RenderDoc), it's not that hard to hack RenderDoc to use its hooks to run arbitrary code on each Present call of the chain I'm interested in. I've not had a chance to try that out yet, so this ...

Joint coordinates alone don't give you enough information about rotation. For example, hold out your arm to your side. Notice that you still have one degree of freedom to twist the arm without affecting the positions of your elbow or wrist. Thus, if you had a motion capture format that stored only those coordinates, you would not be able to distinguish ...

I've seen no answer to my question. But after lots of experimentation and further study of Apple documentation for clues I have figured out how to capture GPU generated frames. First, I gave up on the attempt to have the shader write to the screen and an offscreen buffer in the same render pass. The odd (and undocumented as far as I can tell) behavior of ...

I'm not familiar with different motion capture file formats and exactly what they contain, but I have done some work on animating skeletons of life forms so here's my take on it. When you draw something using a skeleton to animate it, you start with a "root" bone which will obviously have a position as can be seen in this example walk.asf file: :root ...

Was interested in this myself and did some digging, I was wondering if they where spectral, but it appears not (although some interesting work on spectral BRDF is here http://web.cs.wpi.edu/~emmanuel/courses/cs563/write_ups/cliffl/cliffl_spectral_brdf.html ) This chat seems to indicate they are camera native linear, probably with sRGB primaries. https://...

Someone points me that this article describes the spectral response of the camera the MERL paper used, and even provides colour transform matrices at the end. Unfortunately, using those transforms result in even worse results than assuming sRGB primaries.
