	Compute the bounding cylinder for the body, in its current pose. Scaling and padding are accounted for.
virtual void	computeBoundingSphere (BoundingSphere &sphere) const =0
	Compute the bounding radius for the body, in its current pose. Scaling and padding are accounted for.
virtual double	computeVolume (void) const =0
	Compute the volume of the body. This method includes changes induced by scaling and padding.
virtual bool	containsPoint (const btVector3 &p, bool verbose=false) const =0
	Check is a point is inside the body.
bool	containsPoint (double x, double y, double z) const
	Check is a point is inside the body.

Member Function Documentation

virtual void bodies::Body::computeBoundingCylinder ( BoundingCylinder & cylinder ) const [pure virtual]

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

Implemented in bodies::Sphere, bodies::Cylinder, bodies::Box, and bodies::ConvexMesh.

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

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

Implemented in bodies::Sphere, bodies::Cylinder, bodies::Box, and bodies::ConvexMesh.

virtual double bodies::Body::computeVolume ( void ) const [pure virtual]

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

Implemented in bodies::Sphere, bodies::Cylinder, bodies::Box, and bodies::ConvexMesh.

virtual bool bodies::Body::containsPoint	(	const btVector3 &	p,
		bool	verbose = `false`
	)			const `[pure virtual]`

Check is a point is inside the body.

Implemented in bodies::Sphere, bodies::Cylinder, bodies::Box, and bodies::ConvexMesh.

bool bodies::Body::containsPoint	(	double	x,
		double	y,
		double	z
	)			const `[inline]`

Check is a point is inside the body.

Definition at line 145 of file bodies.h.

double bodies::Body::getPadding ( void ) const [inline]

Retrieve the current padding.

Definition at line 119 of file bodies.h.

const btTransform& bodies::Body::getPose ( void ) const [inline]

Retrieve the pose of the body.

Definition at line 132 of file bodies.h.

double bodies::Body::getScale ( void ) const [inline]

Retrieve the current scale.

Definition at line 105 of file bodies.h.

shapes::ShapeType bodies::Body::getType ( void ) const [inline]

Get the type of shape this body represents.

Definition at line 91 of file bodies.h.

virtual bool bodies::Body::intersectsRay	(	const btVector3 &	origin,
		const btVector3 &	dir,
		std::vector< btVector3 > *	intersections = `NULL`,
		unsigned int	count = `0`
	)			const `[pure 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.

Implemented in bodies::Sphere, bodies::Cylinder, bodies::Box, and bodies::ConvexMesh.

void bodies::Body::setDimensions ( const shapes::Shape * shape ) [inline]

Set the dimensions of the body (from corresponding shape).

Definition at line 138 of file bodies.h.

Set the pose of the body. Default is identity.

Definition at line 125 of file bodies.h.

void bodies::Body::setScale ( double scale ) [inline]

If the dimension of the body should be scaled, this method sets the scale. Default is 1.0.
