I am an artist who creates various types of computer-controlled computers. I started prototyping a gimble-based XY machine and realized that the necessary math data was not available. I am a pretty decent programmer, but not very good at math. 3D math.
To understand what I need to do, it would be helpful to look at the rig:
Early prototype:
http://roypardi.com/gimble/gimbleSmall.MOV (short video)
http://roypardi.com/gimble/gimbleLarge.mov (larger video)
The two inner rings represent the X / Y axis and are controlled by stepper motors. I want to be able to use both bitmap images and vector data (gcode). Therefore, I need to be able to address a point in two-dimensional space on paper / from my data and find out what orientation it should be in order to get there (that is, how much for each engine step).
I was looking for 2D> 3D projection, Euler angles, etc., but I'm not in my depth. Any pointers, clicking in the right direction, or code snippets will be most welcome. I can understand most programming languages.
