Deep Compositing

[pxm-vray]

Hi,
Is there a plan to introduce a way to generate Deep shadows from camera in Vray for Maya in order to perform Deep Compositing with the resulting image as described in this website?

There is an example in the V-Ray SDK that shows how to extact the sub-pixel fragment information from the V-Ray rendering (vraysdk\samples\vray_plugins\output\vray_outputte st). You can modify this sample to save the data to whatever format you wish. Some users have already done so; another example is the VRayStereoscopic helper in 3ds Max, which writes this data to a shade map on disk to speed up sub-sequent rendering of stereo images.

Due to deep shadow maps being patented, we cannot support them directly as a file format. Further on, deep shadow maps are not very well suitable for this purpose, as they cannot store discrete (non-floating point) information like object IDs and such. If you know of a non-proprietary format that we can use, and which can store deep raster data, let us know and we can look into supporting it.

Best regards,
Vlado

Vlado,

Is the VRayStereoscopic helper in 3ds Max something that is planned for the Maya version? Just curious? sounds awesome.

What about hdf5 ?

It looks way more complicated than necessary...
