To utilize our skybox images in Panda3D, we'll need to create a
cubemap is a special kind of 3D texture in Panda3D that will take our six images, make them into a cube, and shrink wrap them onto an object. This process can create distortions on complex objects, but on a simple object like a sphere it works beautifully. Once we have the
cubemap, we'll need to create 3D texture coordinates on the sphere so that we can use it. After that, we'll apply the
cubemap to the sphere, set some render attributes on the
NodePath, and then save it out into a bam file.
