The remaining chapters of this book focus on improving the visual quality of the rendered scene. By the end of this chapter, we’ll be able to render objects that look solid (as opposed to wireframe). We already developed an algorithm to draw filled triangles, but as we will see, using that algorithm correctly in a 3D scene is not as simple as it might seem!

Rendering Solid Objects ...
