Detailed Description

A triangle mesh contains vertices and triangles.

The triangle mesh class stores the attribute data in key-value maps. There are two maps: the vertex attributes map, and the triangle attribute map.

• Default attribute: vertex_attr_["positions"], triangle_attr_["indices"]
  • Vertex positions
    • TriangleMesh::GetVertexPositions()
    • TriangleMesh::SetVertexPositions(const Tensor& vertex_positions)
    • TriangleMesh::HasVertexPositions()
    • Value tensor must have shape {num_vertices, 3}.
  • Triangle indices
    • TriangleMesh::GetTriangleIndices()
    • TriangleMesh::SetTriangleIndices(const Tensor& triangle_indices)
    • TriangleMesh::HasTriangleIndices()
    • Value tensor must have shape {num_triangles, 3}.
  • Created by default, required for all triangle meshes.
  • The device of vertex positions and triangle indices must be the same. They determine the device of the trianglemesh.
• Common attributes: vertex_attr_["normals"], vertex_attr_["colors"] triangle_attr_["normals"], triangle_attr_["colors"]
  • Vertex normals
    • TriangleMesh::GetVertexNormals()
    • TriangleMesh::SetVertexNormals(const Tensor& vertex_normals)
    • TriangleMesh::HasVertexNormals()
    • Value tensor must have shape {num_vertices, 3}.
    • Value tensor can have any dtype.
  • Vertex colors
    • TriangleMesh::GetVertexColors()
    • TriangleMesh::SetVertexColors(const Tensor& vertex_colors)
    • TriangleMesh::HasVertexColors()
    • Value tensor must have shape {num_vertices, 3}.
    • Value tensor can have any dtype.
  • Triangle normals
    • TriangleMesh::GetTriangleNormals()
    • TriangleMesh::SetTriangleNormals(const Tensor& triangle_normals)
    • TriangleMesh::HasTriangleNormals()
    • Value tensor must have shape {num_triangles, 3}.
    • Value tensor can have any dtype.
  • Triangle colors
    • TriangleMesh::GetTriangleColors()
    • TriangleMesh::SetTriangleColors(const Tensor& triangle_colors)
    • TriangleMesh::HasTriangleColors()
    • Value tensor must have shape {num_triangles, 3}.
    • Value tensor can have any dtype.
  • Not created by default.
  • For all attributes above, the device must be consistent with the device of the triangle mesh.
• Custom attributes: e.g. vetex_attr_["labels"], triangle_attr_["labels"]
  • Use generalized helper functions, e.g.:
    • TriangleMesh::GetVertexAttr(const std::string& key)
    • TriangleMesh::SetVertexAttr(const std::string& key, const Tensor& value)
    • TriangleMesh::HasVertexAttr(const std::string& key)
    • TriangleMesh::GetTriangleAttr(const std::string& key)
    • TriangleMesh::SetTriangleAttr(const std::string& key, const Tensor& value)
    • TriangleMesh::HasTriangleAttr(const std::string& key)
  • Not created by default. Users can add their own custom attributes.
  • Value tensor must be on the same device as the triangle mesh.

Note that the we can also use the generalized helper functions for the default and common attributes.

This runs on the CPU.

Parameters

		int	parallel_partitions = 1,
		int	nthreads = 0
	)

Creates an UV atlas and adds it as triangle attr 'texture_uvs' to the mesh.

Input meshes must be manifold for this method to work.

The algorithm is based on:

• Zhou et al, "Iso-charts: Stretch-driven Mesh Parameterization using Spectral Analysis", Eurographics Symposium on Geometry Processing (2004)
• Sander et al. "Signal-Specialized Parametrization" Europgraphics 2002

This function always uses the CPU device.

Parameters

size	The target size of the texture (size x size). The uv coordinates will still be in the range [0..1] but parameters like gutter use pixels as units.
gutter	This is the space around the uv islands in pixels.
max_stretch	The maximum amount of stretching allowed. The parameter range is [0..1] with 0 meaning no stretch allowed.
parallel_partitions	The approximate number of partitions created before computing the UV atlas for parallelizing the computation. Parallelization can be enabled with values > 1. Note that parallelization increases the number of UV islands and can lead to results with lower quality.
nthreads	The number of threads used when parallel_partitions is > 1. Set to 0 for automatic number of thread detection.

Returns

Tuple with (max stretch, num_charts, num_partitions) storing the actual amount of stretch, the number of created charts, and the number of parallel partitions created.
