Computes the surface area of this object.
Implements toxic::IBoundedObject. |

|
Given a point in the unit square (the set of points in [0..1]^2), this method computes the corresponding surface point and normal (both are expressed in world space). Implements toxic::IBoundedObject. |
|
|
Returns the Axis Aligned Bounding Box of this object. The AABB is expressed in world space. Implements toxic::IBoundedObject. |

This method returns true if the ray intersect the object, or false otherwise. If 'hit' is not null, intersection data are reported through the 'hit' parameter (only if an intersection has been found; if no intersection has been found, the 'hit' parameter is left unchanged). The ray is expressed in world space.
