Member Function Documentation

draw()

virtual void rt::GraphicalObject::draw ( Viewer &  )

pure virtual

This method is called by Scene::draw() at each frame to redisplay objects in the OpenGL window.

Implemented in rt::Sphere.

getMaterial()

virtual Material rt::GraphicalObject::getMaterial ( Point3  p )

pure virtual

Returns

the material associated to this part of the object

Implemented in rt::Sphere.

getNormal()

virtual Vector3 rt::GraphicalObject::getNormal ( Point3  p )

pure virtual

Returns

the normal vector at point p on the object (p should be on or close to the sphere).

Implemented in rt::Sphere.

init()

virtual void rt::GraphicalObject::init ( Viewer &  )

pure virtual

This method is called by Scene::init() at the beginning of the display in the OpenGL window. May be useful for some precomputations.

Implemented in rt::Sphere.

rayIntersection()

virtual Real rt::GraphicalObject::rayIntersection ( const Ray &  ray, Point3 &  p  )

pure virtual

Parameters

[in]	ray	the incoming ray
[out]	returns	the point of intersection with the object (if any), or the closest point to it.

Returns

either a real < 0.0 if there is an intersection, or a kind of distance to the closest point of intersection.

Implemented in rt::Sphere.
