ludus::foundation::geometry::FrameSample¶

Struct

One baked frame sample. Vectors are unit length and chunk-relative (Rounded).

Normal is the transported reference direction, perpendicular to Tangent. Samples are ordered by span then parameter; each run starts and ends with a sample, and a joint inside a run has samples at both span sides.

Fields¶

Parameter¶

SegmentParameter ludus::foundation::geometry::FrameSample::Parameter {}
