Detailed Description

Variable cone emissive closure

This primitive emits in a cone having a configurable penumbra area where the light decays to 0 reaching the outer_angle limit. It can also behave as a lambertian emitter if the provided angles are PI/2, which is the default

float GenericEmissiveClosure::pdf	(	const Vec3 &	Ng,
		const Vec3 &	omega_out
	)		const [inline]

Return the probability distribution function in the direction omega_out, given the parameters and the light's surface normal. This MUST match the PDF computed by sample().
