Constructor & Destructor Documentation

IBoundedObject::IBoundedObject (  const sheep::Matrix4 &  m, const ISurfaceShader *  surface_shader = 0, IntersectionMask  intersection_mask = INTERSECT_ALL_RAYS )

m is the object space to world space transformation matrix. The 'surface_shader' pointer may be null because some objects (like the Collection and Octree objects) don't need a shader. Definition at line 28 of file iboundedobject.cpp.

virtual toxic::IBoundedObject::~IBoundedObject (   )  [inline, virtual]

Member Function Documentation

virtual sheep::Real toxic::IBoundedObject::ComputeSurfaceArea (   )  const [pure virtual]

Computes the surface area of this object. Implemented in toxic::Cube, toxic::DummyObject, toxic::Mesh, toxic::Octree, toxic::Ring, toxic::Sphere, and toxic::Square. Referenced by toxic::IAreaLight::Finalize().

virtual void toxic::IBoundedObject::EvaluateSurface (  const sheep::Point2 &  input, sheep::Point3 *  point, sheep::Vector3 *  geometric_normal )  const [pure virtual]

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). Implemented in toxic::Cube, toxic::DummyObject, toxic::Mesh, toxic::Octree, toxic::Ring, toxic::Sphere, and toxic::Square. Referenced by toxic::IAreaLight::ComputeIrradiance(), and toxic::IAreaLight::GeneratePhotonRay().

virtual const sheep::AABB3& toxic::IBoundedObject::GetAABB (   )  const [pure virtual]

Returns the Axis Aligned Bounding Box of this object. The AABB is expressed in world space. Implemented in toxic::Cube, toxic::DummyObject, toxic::Mesh, toxic::Octree, toxic::Ring, toxic::Sphere, and toxic::Square. Referenced by toxic::Octree::object_voxel_intersector::Intersect().
