	Compute isosurface mesh for isovalue.
Mesh *	computeIsosurfaceHalfFloat (const TypedImage< unsigned short > *volume, const TypedImage< unsigned char > *volumeColor, float isovalue, bool aboveIsovalue=false)
	Compute isosurface mesh for isovalue.

Function Documentation

computeIsosurface()

template<typename T>

Mesh * computeIsosurface	(	const TypedImage< T > *	volume,
		const TypedImage< unsigned char > *	volumeColor,
		float	isovalue,
		bool	aboveIsovalue = false,
		const TypedImage< unsigned char > *	mask = nullptr )

Compute isosurface mesh for isovalue.

The output coordinate for voxel (x,y,z) is (x,y,z)*spacing. The spacing is taken from the volume.

Parameters

volume	float buffer with volume
volumeColor	optional 3 channel RGB color values for each voxel
isovalue	iso value
aboveIsovalue	true if the interior of the mesh is greater than the isovalue
mask	optional pointer to a unsigned char typed image forming a mask. If supplied, only faces that lie within the mask are added.

Returns

pointer to mesh object representing isosurface if successful, zero otherwise. Caller has to relase memory.

computeIsosurfaceHalfFloat()

Mesh * computeIsosurfaceHalfFloat	(	const TypedImage< unsigned short > *	volume,
		const TypedImage< unsigned char > *	volumeColor,
		float	isovalue,
		bool	aboveIsovalue = false )

Compute isosurface mesh for isovalue.

The output coordinate for voxel (x,y,z) is (x,y,z)*spacing. The spacing is taken from the volume.

Parameters

volume	half float buffer with volume
volumeColor	optional 3 channel RGB color values for each voxel
isovalue	iso value
aboveIsovalue	true if the interior of the mesh is greater than the isovalue

Returns

pointer to mesh object representing isosurface if successful, zero otherwise. Caller has to relase memory.
