Detailed Description

CPU-side capture for subdivision surface deformation. Copies the rest surface and projects positions onto it via ray intersection. The GT topology building and ptex conversion must be performed externally (GT symbols can't link from GU).

void GU_SurfaceDeform::SubdCapture::init

(

const GU_Detail &

restSurfaceGdp

)

Copy rest surface and build ray intersect.

bool GU_SurfaceDeform::SubdCapture::isValid ( ) const

template<typename PA >

bool GU_SurfaceDeform::SubdCapture::project ( UT_IntArray &  coarseFace, UT_FloatArray &  coarseU, UT_FloatArray &  coarseV, const PA &  positions  )

inline

Project positions onto the rest surface coarse mesh. Outputs per-position: coarse face index (prim index into rest gdp), barycentric u/v. Face index is -1 if the point was not captured. PA must support operator[](int) -> UT_Vector3 and size() -> int. Returns false on hard errors (invalid state).
