Detailed Description

This class represents a box and is defined by its center and the length of the sides.

Member Function Documentation

int RayBox::drawOpenGL ( int  materialIndex)

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

Implements RayShape.

double RayBox::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 RayBox::read ( FILE *  fp,
int *  materialIndex 

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

BoundingBox3D RayBox::setBoundingBox ( void  )

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

Implements RayShape.

void RayBox::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 RayBox::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.
