Detailed Description

This class represents a cone whose central axis isparallel to the y-axis, and is defined by the center of the cone, the height from the tip to the base and the base of the cone.

Member Function Documentation

int RayCone::drawOpenGL ( int  materialIndex)
virtual

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

Implements RayShape.

double RayCone::intersect ( Ray3D  ray,
struct RayIntersectionInfo iInfo,
double  mx = -1 
)
virtual

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 RayCone::read ( FILE *  fp,
int *  materialIndex 
)

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

BoundingBox3D RayCone::setBoundingBox ( void  )
virtual

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

Implements RayShape.

void RayCone::setUpOpenGL ( int  cplx)
virtual

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 RayCone::write ( int  indent,
FILE *  fp = stdout 
)
virtual

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.
