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

virtual 
This method calls the necessary OpenGL commands to render the primitive.
Implements RayShape.

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 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

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

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.

virtual 
class RayMaterial* RayTriangle::material 
The material associated with the triangle
class RayVertex* RayTriangle::v[3] 
The vertices of the triangle
