ludus::content::scene_format::VertexRecordV6¶

Struct

Version 6 vertex: a VertexRecord plus a mesh-local tangent frame. Tangent.w is +1 or -1 (bitangent = cross(Normal, Tangent.xyz) * w, MikkTSpace/glTF convention) with an XYZ whose component perpendicular to the normalized Normal is longer than MIN_TANGENT_PERPENDICULAR, or 0 with zero XYZ when the vertex has no tangent and consumers derive a frame from texture coordinates.
