Method Description
ComputeCenter ( ) : Vector3

Computes the center of the shape. This can be considered its center of mass.
ComputeCenter ( IList vertices ) : Vector3

Computes the center of a convex hull defined by the point set.
ComputeCenter ( IList vertices, IList outputLocalSurfaceVertices ) : Vector3

Computes the center and surface triangles of a convex hull defined by a point set.
ComputeCenter ( IList vertices, IList outputSurfaceTriangles, IList outputLocalSurfaceVertices ) : Vector3

Computes the center and surface triangles of a convex hull defined by a point set.
ComputeCenter ( IList vertices, float &volume ) : Vector3

Computes the center and volume of a convex hull defined by a pointset.
ComputeCenter ( IList vertices, float &volume, IList outputSurfaceTriangles, IList outputLocalSurfaceVertices ) : Vector3

Computes the center, volume, and surface triangles of a convex hull defined by a point set.
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.
ComputeCenter ( float &volume, IList outputSurfaceTriangles, IList outputLocalSurfaceVertices ) : Vector3

Computes the center, volume, and surface triangles of the convex hull shape.
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 ( 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.
ComputeVolumeDistribution ( float volume, IList localSurfaceTriangles ) : Matrix3x3

Computes the volume distribution of the convex hull, its volume, and its surface triangles.
