Function Documentation

MR_findVertexUV()

MRC_API MR_std_optional_MR_Vector2f * MR_findVertexUV	(	const MR_MeshTopology *	topology,
		MR_VertId	v,
		const MR_TriCornerUVCoords *	triCornerUvCoords )

returns UV-coordinates at the given vertex if they are the same in all surrounding triangles; otherwise returns std::nullopt Generated from function MR::findVertexUV. Parameter topology can not be null. It is a single object. Parameter triCornerUvCoords can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_std_optional_MR_Vector2f_Destroy() to free it when you're done using it.

MR_findVertexUVs()

MRC_API MR_std_optional_MR_VertCoords2 * MR_findVertexUVs	(	const MR_MeshTopology *	topology,
		const MR_TriCornerUVCoords *	triCornerUvCoords )

if all mesh vertices have unique UV-coordinates in all triangles, then returns them; otherwise returns std::nullopt Generated from function MR::findVertexUVs. Parameter topology can not be null. It is a single object. Parameter triCornerUvCoords can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_std_optional_MR_VertCoords2_Destroy() to free it when you're done using it.

MR_sampleVertexColor()

MRC_API MR_Color MR_sampleVertexColor	(	const MR_Mesh *	mesh,
		MR_VertId	v,
		const MR_MeshTexture *	tex,
		const MR_TriCornerUVCoords *	triCornerUvCoords )

computes the color in the given vertex of mesh textured per-triangle's-corner; if the vertex has different colors in different triangles, then angle-weight average is computed Generated from function MR::sampleVertexColor. Parameter mesh can not be null. It is a single object. Parameter tex can not be null. It is a single object. Parameter triCornerUvCoords can not be null. It is a single object.

MR_sampleVertexColors()

MRC_API MR_VertColors * MR_sampleVertexColors	(	const MR_Mesh *	mesh,
		const MR_MeshTexture *	tex,
		const MR_TriCornerUVCoords *	triCornerUvCoords )

computes the colors in the vertices of mesh textured per-triangle's-corner; if one vertex has different colors in different triangles, then angle-weight average is computed Generated from function MR::sampleVertexColors. Parameter mesh can not be null. It is a single object. Parameter tex can not be null. It is a single object. Parameter triCornerUvCoords can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_VertColors_Destroy() to free it when you're done using it.
