```cs public class CylinderPrimitive : Primitive { public float radius = 1; public float length = 1; public Matrix4F transform = Matrix4F.Identity; } ``` This is the same as [[CylinderPrimitive]] but with rounded caps on either end that extend **outside** the ends of the cylinder, i.e. the real length of this primitive is `length + radius * 2`. > WARNING: the `transform` matrix should only contain rotation and translation operations, not scale. The size of the capsule should be controlled via the `radius` and `length` properties
