Member Function Documentation

template<class T >

void vmml::frustum_culler< T >::setup

(

const matrix< 4, 4, T > &

proj_modelview

)

Set up the culling state using a 4x4 projection*modelView matrix.

Setup the culler by extracting the frustum planes from the projection matrix.

The projection matrix should contain the viewing transformation.

template<class T >

void vmml::frustum_culler< T >::setup	(	const vec3 &	nlt,
		const vec3 &	nrt,

		const vec3 &	nrb,
		const vec3 &	flt,
		const vec3 &	frt,
		const vec3 &	flb,
		const vec3 &	frb
	)

Set up the culling state using the eight frustum corner points.

Corner naming is n(ear)|f(ar), l(eft)|r(ight), t(op)|b(ottom)
