template<typename T >

T UTsignedSolidAngleTri	(	const UT_Vector3T< T > &	a,
		const UT_Vector3T< T > &	b,
		const UT_Vector3T< T > &	c,
		const UT_Vector3T< T > &	query
	)

Returns the signed solid angle subtended by triangle abc from query point.

WARNING: This uses the right-handed normal convention, whereas most of Houdini uses the left-handed normal convention, so either negate the output, or swap b and c if you want it to be positive inside and negative outside.
