Public Methods

Method Description
ComputeCenter ( ) : Vector3

Computes the center of the shape. This can be considered its center of mass.
ComputeCenter ( float &volume ) : Vector3

Computes the center of the shape. This can be considered its center of mass. This calculation is often associated with the volume calculation, which is given by this method as well.
ComputeDistributionInformation ( ShapeDistributionInformation &shapeInfo ) : void
ComputeMaximumRadius ( ) : float

Computes the maximum radius of the shape. This is often larger than the actual maximum radius; it is simply an approximation that avoids underestimating.
ComputeMinimumRadius ( ) : float

Computes the minimum radius of the shape. This is often smaller than the actual minimum radius; it is simply an approximation that avoids overestimating.
ComputeVolume ( ) : float

Computes the volume of the shape.
ComputeVolumeDistribution ( ) : Matrix3x3

Computes the volume distribution of the shape. The volume distribution can be used to compute inertia tensors when paired with mass and other tuning factors.
ComputeVolumeDistribution ( float &volume ) : Matrix3x3

Computes the volume distribution of the shape as well as its volume. The volume distribution can be used to compute inertia tensors when paired with mass and other tuning factors.
GetBoundingBox ( RigidTransform &shapeTransform, BoundingBox &boundingBox ) : void

Gets the bounding box of the shape given a transform.
GetExtremePoint ( Vector3 direction, RigidTransform &shapeTransform, Vector3 &extremePoint ) : void

Gets the extreme point of the shape in world space in a given direction with margin expansion.
GetExtremePointWithoutMargin ( Vector3 direction, RigidTransform &shapeTransform, Vector3 &extremePoint ) : void

Gets the extreme point of the shape in world space in a given direction.
GetLocalBoundingBox ( RigidTransform &shapeTransform, AffineTransform &spaceTransform, BoundingBox &boundingBox ) : void

Gets the bounding box of the convex shape transformed first into world space, and then into the local space of another affine transform.
GetLocalExtremePoint ( Vector3 direction, Vector3 &extremePoint ) : void

Gets the extreme point of the shape in local space in a given direction with margin expansion.
GetLocalExtremePointWithoutMargin ( Vector3 &direction, Vector3 &extremePoint ) : void

Gets the extreme point of the shape in local space in a given direction.
GetSweptBoundingBox ( RigidTransform &transform, Vector3 &sweep, BoundingBox &boundingBox ) : void

Computes a bounding box for the shape and expands it.
GetSweptLocalBoundingBox ( RigidTransform &shapeTransform, AffineTransform &spaceTransform, Vector3 &sweep, BoundingBox &boundingBox ) : void

Gets the bounding box of the convex shape transformed first into world space, and then into the local space of another affine transform.
RayTest ( Ray &ray, RigidTransform &transform, float maximumLength, RayHit &hit ) : bool

Gets the intersection between the convex shape and the ray.
