Function Documentation

ODE_API dGeomID dCreateSphere	(	dSpaceID	space,
		dReal	radius
	)

Create a sphere geom of the given radius, and return its ID.

Parameters:

space	a space to contain the new geom. May be null.
radius	the radius of the sphere.

Returns:

A new sphere geom.

Remarks:

The point of reference for a sphere is its center.

Retrieves the radius of a sphere geom.

Parameters:

sphere

the sphere to query.

ODE_API dReal dGeomSpherePointDepth	(	dGeomID	sphere,
		dReal	x,
		dReal	y,
		dReal	z
	)

Calculate the depth of the a given point within a sphere.

Parameters:

sphere	the sphere to query.
x	the X coordinate of the point.
y	the Y coordinate of the point.
z	the Z coordinate of the point.

Returns:

The depth of the point. Points inside the sphere will have a positive depth, points outside it will have a negative depth, and points on the surface will have a depth of zero.

ODE_API void dGeomSphereSetRadius	(	dGeomID	sphere,
		dReal	radius
	)

Set the radius of a sphere geom.

Parameters:

sphere	the sphere to set.
radius	the new radius.
