I would like to modify the cregion capture transform for an existing bone capture from within a custom SOP using the HDK. I think I understand the point (region#, weight) pairs attribute and the detail attribute for the capture frame, but the properties with the cregion names and the transform information are more elusive. GEO_Detail provides a number of promising functions, but they seem incomplete.

Can some please provide me some code snippets for the following:
1) Determine the number of cregions in the capture.
2) Map a region index to a cregion path
3) Get access to the 20-byte pCaptData record for a given cregion, for both read and write.

Correction, 20-float pCaptData record, not byte.

Hi!

I don't know if you've got other reasons to move things into the hdk, but you can achieve all the above points using the capture attribute pack/unpack SOP nodes. Could save you a lot of compiling fun and games

Good suggestion, and I may do unpack/pack as an interim step. I'd be adding this to an existing custom SOP, and would like to avoid the need for extra SOPs before and after to keep things tight.
