Look under the hood - methods


Newb here. Is it possible to see the code that makes up different methods such as rect(), ellipse() etc.?


Sometime you will find things in the source code – for example, check out TRIANGLE_FAN or sphere() to see exactly how it works. Sometimes you will find the interface, but the actual lowest-level implementation of primitives will depend on the renderer – for example, how points or lines are handled in the JAVA2D, P2D, or P3D. P2D and P3D are OpenGL-based, so there some low-level drawing logic is actually happening in OpenGL, not in Processing(Java).
