Function Documentation

void R_AddBspRRef	(	const mBspModel_t *	model,
		const vec3_t	origin,
		const vec3_t	angles,
		const bool	forceVisibility
	)

Adds bsp render references.

Note: If forceVisibility is set, will mark the surfaces of the given bsp model as visible for this frame.

Parameters

[in]	model	The bsp model to add to the render chain
[in]	origin
[in]	angles
[in]	forceVisibility	force model to be fully visible

bool R_CullSphere	(	const vec3_t	centre,
		const float	radius,
		const unsigned int	clipflags
	)

Performs a spherical frustum check.

Parameters

[in]	centre	The world coordinate that is the center of the sphere
[in]	radius	The radius of the sphere to check the frustum for
[in]	clipflags	Can be used to skip sides of the frustum planes

Returns: true if the sphere is completely outside the frustum, false otherwise
