[ Up: Operation Reference ]

Modifies the level-of-detail of the input MeshModelInterface. Reducing the level-of-detail of a mesh abstracts its surface by removing selected triangles in a way that maintains the important visual features of the mesh. This can be useful for improving performance of rendering or processing operations without majorly impacting the visual results. A reduced mesh size (in terms of memory / storage space) is another effect of applying this operation. NOTE: This operation will only LOD triangle element types. Other types will be ignored.

Inputs:
MeshModelInterface	Modified-in-place	CSIRO::Mesh::MeshModelInterface
LOD reduction		double	0->1 percentage to reduce the mesh
LOD	Deprecated	double	The level-of-detail error. A higher LOD value means that more triangles will be removed from the model. A value less than zero will disable this functionality. LOD error level input has been replace by the more intuitive 'LOD reduction' input - a 0->1 percentage deduction.
Pre-LOD merge distance	Deprecated	double	Nodes with a proximity of this distance will be merged together as a pre-processing step. This can help speed up the algorithm. A value less than zero will disable this functionality. Pre-LOD merge is a very inefficient implementation of the pre-process that should not be used.
Max tri normal change (deg)		double	The maximum allowed change in a triangle's normal direction (in degrees). A smaller value will result in the output mesh having a closer resemblance to the input mesh, but the detail will be reduced less.
Min tri area/length ratio		double	Minimum triangle area-to-length ratio allowed. This can help avoid splinters from being generated in the output mesh.
Free edge collapse angle (deg)		double	The angle used to determine whether a free edge (non-manifold edge) should be collapsed when 'Preserve free edges' is enabled.
Max new edge length		double	The maximum allowed edge length of a triangle in the output mesh. Useful for models with large homogenous regions that will be LODed down to large, single triangles. This will ensure that the triangles produced have a maximum size.
Save node states		bool	If enabled, node states are created on the output mesh for values used to perform the LOD. This can be useful for debugging.
Preserve free edges		bool	Do not collapse non-manifold edges unless angle change will be under 'Free edge collapse angle'
Stop at collapse number		int	Upper bound on the number of collapse operations performed.
Trace Progress		bool	If enabled, progress output is printed to the log.
Outputs:
MeshModelInterface		CSIRO::Mesh::MeshModelInterface
Reduction %		double	The percentage of triangles removed (0->1)
