Detailed Description

This class represents a triangle and is specified by three pointers to the three vertices that define it.

Member Function Documentation

int RayTriangle::drawOpenGL ( int  materialIndex)

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

Implements RayShape.

double RayTriangle::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 RayTriangle::read ( FILE *  fp,
int *  materialIndex,
RayVertex vList,
int  vSize 

This method reads in a RayTriangle from a .ray file. A pointer to the material associated to the triangle is set. The vertex positions are determined by reading in the vertex indices from the file and then looking them up in the vertex list vList

BoundingBox3D RayTriangle::setBoundingBox ( void  )

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

Implements RayShape.

void RayTriangle::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 RayTriangle::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.
