lisux Posted September 27, 2005 Share Posted September 27, 2005 I have seen in recent Houdini builds a new image supported image format, is a variation over the classic Houdini RAT format, in the file type dropbow i can see: ... Random Access Texture (TBF format) ... Anybody knows what TBF stands for? What are the differencies between the clasic RAT format and the RAT(TBF) format?

A TBF could represent a Point Cloud for occlusion, or a Deep shadow map, or hold the data for an IPR render. They are mip-mapped like a RAT file so they are nice and efficient.

Or i can generate a point cloud and save it using this format? Quote Link to comment Share on other sites More sharing options...

I believe if you set your shadow maps to be Deep Shadows the format they will be stored in will be TBF. You can save out a bunch of points from sops and then use i3dconvert -c to create a TBF file. See i3dconvert -h for more info on creating the TBF. Quote Link to comment Share on other sites More sharing options...
