Constructors

TriangleMesh(IEnumerable<JTriangle>, bool)

Creates a mesh from a "soup" of triangles. Vertices are automatically identified and deduplicated.

public TriangleMesh(IEnumerable<JTriangle> soup, bool ignoreDegenerated = false)

Parameters

soup IEnumerable<JTriangle>

ignoreDegenerated bool

TriangleMesh(ReadOnlySpan<JTriangle>, bool)

Creates a mesh from a "soup" of triangles. Vertices are automatically identified and deduplicated.

public TriangleMesh(ReadOnlySpan<JTriangle> soup, bool ignoreDegenerated = false)

Parameters

soup ReadOnlySpan<JTriangle>

ignoreDegenerated bool

TriangleMesh(ReadOnlySpan<JVector>, ReadOnlySpan<int>, bool)

Creates a mesh from existing vertices and indices.

public TriangleMesh(ReadOnlySpan<JVector> vertices, ReadOnlySpan<int> indices, bool ignoreDegenerated = false)

Parameters

vertices ReadOnlySpan<JVector>

The vertex buffer.

indices ReadOnlySpan<int>

The index buffer (must be a multiple of 3).

ignoreDegenerated bool

Remarks

Vertices with exactly identical positions are canonicalized so adjacency detection also works across duplicated seam vertices in indexed meshes.

TriangleMesh(ReadOnlySpan<JVector>, ReadOnlySpan<ushort>, bool)

Creates a mesh from existing vertices and indices.

public TriangleMesh(ReadOnlySpan<JVector> vertices, ReadOnlySpan<ushort> indices, bool ignoreDegenerated = false)

Parameters

vertices ReadOnlySpan<JVector>

The vertex buffer.

indices ReadOnlySpan<ushort>

The index buffer (must be a multiple of 3).

ignoreDegenerated bool

Remarks

Vertices with exactly identical positions are canonicalized so adjacency detection also works across duplicated seam vertices in indexed meshes.

TriangleMesh(ReadOnlySpan<JVector>, ReadOnlySpan<uint>, bool)

Creates a mesh from existing vertices and indices.

public TriangleMesh(ReadOnlySpan<JVector> vertices, ReadOnlySpan<uint> indices, bool ignoreDegenerated = false)

Parameters

vertices ReadOnlySpan<JVector>

The vertex buffer.

indices ReadOnlySpan<uint>

The index buffer (must be a multiple of 3).

ignoreDegenerated bool

Remarks

Vertices with exactly identical positions are canonicalized so adjacency detection also works across duplicated seam vertices in indexed meshes.
