Detailed Description

Matrix to 6 frustum plane conversion functions.

Member Function Documentation

void SLFrustum::getPointsInViewSpace	(	SLVec3f *	points,
		float	fovV,
		float	ratio,
		float	clipNear,
		float	clipFar
	)

static

Returns frustum points in view space.

void SLFrustum::viewToFrustumPlanes	(	SLPlane *	planes,
		const SLMat4f &	A
	)

static

Calculates the coefficients of the 6 frustum planes from the passed matrix A. See the paper from Gribb and Hartmann: https://www.gamedevs.org/uploads/fast-extraction-viewing-frustum-planes-from-world-view-projection-matrix.pdf

Parameters

planes	Pointer to an array of 6 SLPlanes (L R T B N F)
A	The projection matrix

void SLFrustum::viewToFrustumPlanes	(	SLPlane *	planes,
		const SLMat4f &	projectionMat,
		const SLMat4f &	viewMat
	)

static

Calculates the coefficients of the 6 frustum planes from the passed projection and view matrices. See the paper from Gribb and Hartmann: https://www.gamedevs.org/uploads/fast-extraction-viewing-frustum-planes-from-world-view-projection-matrix.pdf

Parameters

planes	Pointer to an array of 6 SLPlanes (L R T B N F)
projectionMat	4x4 projection matrix
viewMat	4x4 view matrix
