		const GEO_Detail *	match_src
	)

static

Compute a space transform from camera settings. The ortho_zoom parameter is only used when is_ortho = true.

static UT_Vector3R GEO_PrimVolumeXform::computeResolution	(	SamplingType	sampling_type,
		const UT_Vector3R &	non_uniform_divs,
		fpreal	uniform_divs,
		fpreal	div_size,
		fpreal	z_div_scale,
		UT_Vector3R &	size_inout,
		int	twod_axis = `-1`
	)

static

Compute the resolution (and size) from a common set of parameters. If twod_axis is one of [0,1,2], then that axis clamped to a divisions of 1 and a size of 0. The number of divisions is returned with size set to div_size multiplied by divisions before the z_div_scale.

UT_Vector3R GEO_PrimVolumeXform::computeSize ( ) const

Compute the size for this transform (relative to myCenter)
