Detailed Description

Container for Mesh creation information.

Constructor & Destructor Documentation

MeshInfo()

scenepic::MeshInfo::MeshInfo	(	std::size_t	num_vertices,
		std::size_t	num_triangles,
		bool	has_uvs,
		bool	has_normals,
		bool	has_colors
	)

Constructor.

This will allocate buffers to the given sizes. Note: A mesh cannot have both UVs and color information, though it can have neither.

Parameters

num_vertices	the number of vertices in the mesh
num_triangles	the number of triangles in the mesh
has_uvs	whether the mesh will have vertex UVs
has_normals	whether the mesh will have vertex normals
has_colors	whether the mesh will have vertex colors
