Constructor & Destructor Documentation

◆ Frustum()

Ult::Frustum::Frustum ( )

Frustum constructor.

Member Function Documentation

◆ AddPlane()

void Ult::Frustum::AddPlane ( const Plane & pl )

Copy the input plane to the internal frustum planes.

◆ CalculateFrustum()

void Ult::Frustum::CalculateFrustum	(	const float	angle,
		const float	ratio,
		const float	near,
		const float	far,
		const Vector3D &	camPos,
		const Vector3D &	lookAt,
		const Vector3D &	up )

Initialize as a camera frustum from the input parameters.

◆ GetPlane()

bool Ult::Frustum::GetPlane	(	const int	index,
		Plane *	out ) const

Store the frustum plane at the given index into 'out'.

◆ GetTotalPlanes()

int Ult::Frustum::GetTotalPlanes ( ) const

inline

Return the number of stored frustum planes.

◆ IsBoxVisible()

bool Ult::Frustum::IsBoxVisible	(	const Vector3D &	min,
		const Vector3D &	max )

Returns true if the input box overlaps the frustum.

◆ IsCubeVisible()

bool Ult::Frustum::IsCubeVisible	(	const float	x,
		const float	y,
		const float	z,
		const float	size )

Returns true if the input cube overlaps the frustum.

Parameters

x,y,z	The cube's center position.
size	The half width/length/height of the cube.

◆ IsObbVisible()

bool Ult::Frustum::IsObbVisible ( const OBB & obb )

Returns true if the input oriented bounding-box overlaps the frustum.

◆ IsPointVisible()

bool Ult::Frustum::IsPointVisible	(	const float	x,
		const float	y,
		const float	z )

Returns true if the input point is within the frustum.

◆ IsSphereVisible()

bool Ult::Frustum::IsSphereVisible	(	const float	x,
		const float	y,
		const float	z,
		const float	radius )

Returns true if the input sphere overlaps the frustum.
