The Graphics Codex is a website and app I found that teaches people how to make basic graphics using programming. It has a series of “courses” with projects that allow people to practice the skills they learn. The project I was the most interested in is called “Meshes.” It involves using geometrical shapes (mostly triangles) to create three-dimensional pictures. The course explains how to think topographically, and gives the ins and outs of using algorithms to program the actual displays.
This is an example of how one would use triangles to create 3D shapes in computer graphics. The triangles are left in to show a map, and to get the people seeing the image to “think topographically.”
One thing I found interesting is the course’s definition of topography. It explains that topography is the connectedness of the points on a two-dimensional surface in three-dimensional space. I learned that while the “mesh” part animates in graphics, the actual connectedness stays the same, and this is an important point in computer graphics.
