[SOLVED] Csci 385 project 1: showcase

This assignment has you invent several geometric models of surfaces so that they can be displayed in a WebGL application. We model surfaces as collections of triangular facets that sit in 3-space. Each of the three corners of each facet are specified by an (x,y,z) coordinate, and the coloring of the facets are given as (red, green, blue) triples. Having describing all the vertices and facets of the surface, and its material properties, the surface description is then sent to the graphics hardware to be displayed on a WebGL canvas embedded in a web page.

The starting code for this assignment can be downloaded here. It includes a web page showcase.html that relies on the Javascript file showcase.js and a few other supporting files. When that web page is loaded into the browser, it can already display one of three objects:

These models are generated and displayed by these functions:

The actual names are makeTetrahedron, makeCube, and makeCylinder. We describe this code in more detail below. You will extend the code to describe a few more models and render them as additions to the object showcase app.
