Detailed Description

The Abstract base class for all kind objects in rayGina like geometries, groups and acceleration structures!

This abstract class provides the interface to be implemented by a renderable rayGina object.

virtual const RBool RayGina::CORE::RobBase::getRenderObjects ( RobAccelerator * renderlist ) [pure virtual]

adds several objects to the list that describe the geometry or the instance itself on simple objects
This method is for complex objects, compound objects or objects that needs a tesselation for efficient rayTracing It adds a representation of the object in the list by using one or more other geometries. Example: A tessalation of a NURBS-patch could add lots of triangles which approximate the NURBS-patch
Implemented in RayGina::CORE::RobAABB, RayGina::CORE::RobAccelerator, RayGina::CORE::RobGeometry, RayGina::CORE::RobGroup, RayGina::CORE::RobMesh, RayGina::CORE::RobMeshTriangle, RayGina::CORE::RobSphere, and RayGina::CORE::RobTriangle.

virtual const RBool RayGina::CORE::RobBase::intersect ( RRay * ray ) [pure virtual]

Methode to calc the intersection of an object with a single ray.

Parameters:

ray a pointer to the ray used for intersection calculation The Information for the found intersection (if there is one) will be saved in the ray

Return values:

true if the ray intersects the objeect and stores infos about intersection point within the ray

false if there is no intersection between the ray and the object => no raydata is been modified

Implemented in RayGina::CORE::RobAABB, RayGina::CORE::RobAABspXs, RayGina::CORE::RobAccelerator, RayGina::CORE::RobGeometry, RayGina::CORE::RobGroup, RayGina::CORE::RobMesh, RayGina::CORE::RobMeshTriangle, RayGina::CORE::RobSphere, and RayGina::CORE::RobTriangle.

virtual const RBool RayGina::CORE::RobBase::occlude ( const RRay * ray ) [pure virtual]

Method to calc the intersection of an object with a single shadow ray.
returns true if there is an intersection with the object and the given ray but NO information is saved in the ray
Implemented in RayGina::CORE::RobAABB, RayGina::CORE::RobAABspXs, RayGina::CORE::RobAccelerator, RayGina::CORE::RobGeometry, RayGina::CORE::RobGroup, RayGina::CORE::RobMesh, RayGina::CORE::RobMeshTriangle, RayGina::CORE::RobSphere, and RayGina::CORE::RobTriangle.
