Mesh Normals

Classes
struct	MR::MeshNormals

Typedefs
using	MR::TriangleCornerNormals = std::array<Vector3f, 3>
	normals in three corner of a triangle

Functions
MRMESH_API FaceNormals	MR::computePerFaceNormals (const Mesh &mesh)
	returns a vector with face-normal in every element for valid mesh faces
MRMESH_API void	MR::computePerFaceNormals4 (const Mesh &mesh, Vector4f *faceNormals, size_t size)
	fills buffer with face-normals as Vector4f for valid mesh faces
MRMESH_API VertNormals	MR::computePerVertNormals (const Mesh &mesh)
	returns a vector with vertex normals in every element for valid mesh vertices
MRMESH_API VertNormals	MR::computePerVertPseudoNormals (const Mesh &mesh)
MRMESH_API MeshNormals	MR::computeMeshNormals (const Mesh &mesh)
	computes both per-face and per-vertex normals more efficiently then just calling both previous functions

normals in three corner of a triangle

Function Documentation

computeMeshNormals()

MRMESH_API MeshNormals MR::computeMeshNormals ( const Mesh & mesh )

nodiscard

computes both per-face and per-vertex normals more efficiently then just calling both previous functions

computePerCornerNormals()

MRMESH_API Vector< TriangleCornerNormals, FaceId > MR::computePerCornerNormals ( const Mesh & mesh, const UndirectedEdgeBitSet * creases )

nodiscard

returns a vector with corner normals in every element for valid mesh faces; corner normals of adjacent triangles are equal, unless they are separated by crease edges

computePerFaceNormals()

MRMESH_API FaceNormals MR::computePerFaceNormals ( const Mesh & mesh )

nodiscard

returns a vector with face-normal in every element for valid mesh faces

computePerFaceNormals4()

MRMESH_API void MR::computePerFaceNormals4	(	const Mesh &	mesh,
		Vector4f *	faceNormals,
		size_t	size )

fills buffer with face-normals as Vector4f for valid mesh faces

computePerVertNormals()

MRMESH_API VertNormals MR::computePerVertNormals ( const Mesh & mesh )

nodiscard

returns a vector with vertex normals in every element for valid mesh vertices

computePerVertPseudoNormals()

MRMESH_API VertNormals MR::computePerVertPseudoNormals ( const Mesh & mesh )

nodiscard

returns a vector with vertex pseudonormals in every element for valid mesh vertices see http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.107.9173&rep=rep1&type=pdf
