This feature is all about lighting. We’ve covered this all in great depth in class already, so there really wasn’t a whole lot that gave me any trouble. The lighting includes ambient, diffuse, and specular lighting (using the Blinn method in particular). Everything I used as a reference came directly from Chris Johnson.
Here are side by side comparisons of the models with and without specular highlights added.
And because I know you all want to see these glorious specular highlights all over those flower petals and dinosaur parts, I’ve included a short video demonstrating all this lighting business.
