SamplePointsUniformlyCPU()

std::array< core::Tensor, 3 > cloudViewer::t::geometry::kernel::trianglemesh::SamplePointsUniformlyCPU	(	const core::Tensor &	triangles,
		const core::Tensor &	vertices,
		const core::Tensor &	triangle_areas,
		const core::Tensor &	vertex_normals,
		const core::Tensor &	vertex_colors,
		const core::Tensor &	triangle_normals,
		const core::Tensor &	texture_uvs,
		const core::Tensor &	albedo,
		size_t	number_of_points
	)

All input tensors must be on CPU, contiguous and the correct shape. normals are computed if either vertex_normals and triangle_normals are not empty (used in that order). colors (Float32) are computed if either albedo and texture_uvs or vertex_colors are not empty (used in that order).
