planetarium - A Processing library for dome projection.

  •    Java

The planetarium library is intended to project 3D Processing sketches on spherical domes, with minimal changes in the code of the sketch. A brief descrition of how it works: a 360° view of the scene is generated by rendering the scene 6 times from each direction: positive x, negative x, and so on. The output of each rendering is stored inside a cube map texture, which is then applied on a sphere representing the dome. Hence, the library calls the draw() method 6 times per frame in order to update the corresponding side of the cube map texture (in reality, only 5 times since the bottom side of the cube map is not invisible on the dome).
