Member Function Documentation

int RaySphere::drawOpenGL ( int  materialIndex)

This method calls the necessary OpenGL commands to render the primitive.

Implements RayShape.

double RaySphere::intersect ( Ray3D  ray,
struct RayIntersectionInfo iInfo,
double  mx = -1 

This method computes the intersection of the shape with the ray. If the ray hits the shape and either mx is less than zero or the intersection occurs at a distance less than mx along the ray the intersection information in iInfo is set and a value greater than 0 is returned. Otherwise, -1 is returned. (This is useful for shadow testing when you may want to ignore hits beyond a certain distance).

Implements RayShape.

int RaySphere::read ( FILE *  fp,
int *  materialIndex 

This method reads in a RaySphere from a .ray file. A pointer to the material associated to the triangle is set.

BoundingBox3D RaySphere::setBoundingBox ( void  )

This method sets and returns a bounding box containing the shape.

Implements RayShape.

void RaySphere::setUpOpenGL ( int  cplx)

This method sets up all the stuff that's necessary prior to OpenGL rendering. The value cplx represents the desired resolution of tessalation for objects such as spheres, cylinders, etc..

Implements RayShape.

void RaySphere::write ( int  indent,
FILE *  fp = stdout 

This method writes the RayShape out to a .ray file, indenting the output by the specified amount. If no file is specified, the information gets written to stdout.

Implements RayShape.
