function
Rendering::MeshUtils::Simplification::simplifyMesh

public

Mesh * simplifyMesh(	Mesh *	mesh,
	uint32_t	numberOfTriangles,
	float	threshold,
	bool	useOptimalPositioning,
	float	maxAngle,
	const weights_t &	weights
)

Simplify the given mesh to a total number of triangles given in the parameters. This method will return a new mesh and leave the original unchanged. Hint: Vertex weight should contain normalization of vertex position (divide by BoundingBox.extendMax)

Parameters

mesh

Mesh to be simplified

numberOfTriangles

the number of polygons the returned mesh should have

threshold

maximum distance of vertices not connected by an edge for pair selection

useOptimalPositioning

enables/disables calculation of optimal positioning for vertices

maxAngle

maximum angle a face may rotate per merge step (value is arccos of angle [-1, 1])

weights

weights for all attributes using indices defined above

Returns

new simplified mesh, null if simplification failed
