• Add min/max bounds and collision bounds to camera in machine.ini (resolves #86)
• Improved viewport navigation
  • Zooming now translates the camera
  • Added perspective/orthographic in new "Camera" menu (resolves #116)
  • Resolves #115
• Overhauled proxy objects with proxy_objects.py
  • Implemented AABBObject3D, CylinderObject3D, OBJObject3D classes
  • Add vec3/line segment intersection methods to BoundingBox class
  • Removed proxyconfig_frame.py and proxy3d.py
• Implement picking and rendering for proxy objects in glcanvas
  • Improve shaders (add "diffuse" and "solid" shaders)
  • Proxy objects' picking ids are MAX_ID - id, where MAX_ID is the id of pure white (background) minus 1
  • MAX_ID is the limit for |cameras| + |actions| + |proxy objects| because of how picking is done (probably not an issue, as it's over 16 million)
• pathgen_toolbar creates paths with a cost function and accounts for collision/intersection with proxy objects (resolves #102)
  • Currently actions at each point must be manually specified, should overhaul action representation in the future though
  • Todo in the future: https://github.com/YPM-Informatics/COPISClient/issues/120
