Public Member Functions
virtual void	computeBoundingSphere (BoundingSphere &sphere) const
	Compute the bounding radius for the body, in its current pose. Scaling and padding are accounted for.

Member Function Documentation

void bodies::Sphere::computeBoundingSphere ( BoundingSphere & sphere ) const [virtual]

Compute the bounding radius for the body, in its current pose. Scaling and padding are accounted for.

Implements bodies::Body.

Definition at line 160 of file bodies.cpp.

double bodies::Sphere::computeVolume ( void ) const [virtual]

Compute the volume of the body. This method includes changes induced by scaling and padding.

Implements bodies::Body.

Definition at line 155 of file bodies.cpp.

bool bodies::Sphere::containsPoint	(	const tf::Vector3 &	p,
		bool	verbose = `false`
	)		const `[virtual]`

Check is a point is inside the body.

Implements bodies::Body.

bool bodies::Sphere::intersectsRay	(	const tf::Vector3 &	origin,
		const tf::Vector3 &	dir,
		std::vector< tf::Vector3 > *	intersections = `NULL`,
		unsigned int	count = `0`
	)		const `[virtual]`

Check is a ray intersects the body, and find the set of intersections, in order, along the ray. A maximum number of intersections can be specified as well. If that number is 0, all intersections are returned.
