3D Sphere Phong Specularity

Hello;

This is a very simple project for anyone with a clear understanding of 3D rendering / raytracing. I'm posting this project is simply to further my understanding of how raytracing works.

The following code shades a 3D sphere:

for (y=0;y<screenHeight;y++)

for (x=0;x<screenWidth;x++)

if (sqr((x-xcenter)*(x-xcenter)+(y-ycenter)*(y-ycenter))<radius)

{

vx=(x-xcenter);

vy=(y-xcenter);

vz=sqr(radius*radius-vx*vx-vy*vy);

vl=sqr(vx*vx+vy*vy+vz*vz);

co_angle=(lx*vx+ly*vy+lz*vz)/(ll*vl);

pixel=co_angle*255;

}

lx,ly,lz are light location. x&y center are simply screen center location for the sphere. ll is light length: ll=sqr(lx*lx+ly*ly+lz*lz);

I would like someone to implement specular lighting (shinyness) based on this code. The specular lighting should have the basic features which are intensity, shinyness and color. Ideally, the project could be completed by simply expanding on this code and resubmitting it back to me.

Any questions, feel free to ask.

Attached is an image showcasing the results I'm looking for.
