for_meshes()

static VertexLayout MayaFlux::Kakshya::VertexLayout::for_meshes ( uint32_t  stride = 60 )

inlinestatic

Factory: layout for MeshVertex (position, color, weight, uv, normal, tangent)

Matches MeshVertex field order exactly (60 bytes): loc 0 offset 0 VERTEX_POSITIONS_3D position loc 1 offset 12 VERTEX_COLORS_RGB color loc 2 offset 24 SCALAR_F32 weight loc 3 offset 28 TEXTURE_COORDS_2D uv loc 4 offset 36 VERTEX_NORMALS_3D normal loc 5 offset 48 VERTEX_TANGENTS_3D tangent

Identical offset table to for_points() and for_lines(). FieldOperator processes all three types with the same constants.

Parameters

stride

Override stride (default: sizeof(MeshVertex) == 60)
