Member Function Documentation

virtual SurfacePatch3D* SurfacePatch3D::duplicate (   )  const [pure virtual]

Create a duplicate of the object. Must be of the same type! Returns: An exact duplicate of the object. Implemented in Box, Cylinder, Isosurface, Plane, Sphere, and TrianglePatch.

virtual Vector3 SurfacePatch3D::getBoundingMax (   )  const [pure virtual]

Get bounding dimension (maximum edge). Implemented in Box, Object3D, Sphere, and TrianglePatch.

virtual Vector3 SurfacePatch3D::getBoundingMin (   )  const [pure virtual]

Get bounding dimension (minimum edge). Implemented in Box, Object3D, Sphere, and TrianglePatch.

virtual bool SurfacePatch3D::hasFinitBounding (   )  const [pure virtual]

Returns true if the surface can be enclosed by a finit box. Implemented in Box, Object3D, Sphere, and TrianglePatch.

Intersection * SurfacePatch3D::intersect (  const Ray &  r  )  const [virtual]

Intersect object with ray. Parameters: r  the Ray Returns: 0 if no intersection else Intersection object Reimplemented in Object3D.

virtual DBL SurfacePatch3D::intersectBounding (  const Ray &  r, DBL  tmax )  const [pure virtual]

Intersect Bounding with Ray limited to maximum time. Parameters: r  the Ray tmax  Maximum intersection time. Returns: -1 if no intersection, INTERSECTION_TIME_EPSILON if Ray's origin is inside the bounding. Otherwise it returns the time of first intersection with box. Implemented in Object3D, and TrianglePatch.

virtual DBL SurfacePatch3D::intersectBounding (  const Ray &  r  )  const [pure virtual]

Intersect Bounding with Ray. Parameters: r  the Ray Returns: -1 if no intersection, INTERSECTION_TIME_EPSILON if Ray's origin is inside the bounding. Otherwise it returns the time of first intersection with box. Implemented in Object3D, and TrianglePatch.

virtual Intersection* SurfacePatch3D::intersectLimitedTime (  const Ray &  r, DBL  maxtime )  const [pure virtual]

Intersect object with ray limited to maximum time. Parameters: r  the Ray maxtime  maximal intersecting time Returns: 0 if no intersection else Intersection object Implemented in Object3D, and TrianglePatch.

virtual void SurfacePatch3D::prepareToRender (   )  [inline, virtual]

Prepare object for render process. Some optimisations can be done only before the rendering starts. This is the method that is to be called just before doing so. The object has to be tolerant against multiple calls of this method. Reimplemented in ObjectContainer.
