Wildbits K2 - VS1053b Geometry Kernel Demo

Wildbits K2 computer has a vs1053b audio chip which supports plugins for adding patches, effects, spectrum analysis, etc. I created a plugin to use the chip's dsp for simple 3d geometry, projection and clipping which off-loads those calculations from the 65816 cpu. This video shows a demo of its capabilities: - translation and 3 axis rotation in both objects and camera. - object scaling - object caching in chip memory The animation dataset was generated by blender. Each frame provides the world coord position and the local rotation angles for each object. I am using the control keys to move and rotate the camera during the video. The plugin transforms local object coords to camera view space and then projects and clips edges onto screen coords. The cpu uses the K2s fpga based line drawing to draw lines into double buffered bitmap memory. Bitmap clear is done using a vdma fill
