Virtual Rubiks Cube

The aims of this example are: Produce an OpenFL based Rubik's cube simulation Experiment with OpenGL in OpenFL working through Learn OpenGL - Graphics Programming by Joey de Vries Experiment with 2D and 3D graphics in the one application

The stack used is lime, openfl and haxeui.

Bugs

• accordion sections are enabled for things like blending, culling, framebuffer when the configuration is no active. Not a huge deal but the controls cannot be effective then.

To Do

• Immediate

  • both culling and framebuffer are much smaller scale scenes (unit cubes not 64) and the keyboard WASD movement does not account for that - add scaling
  • refactor point lights to base scene
  • the reset* class of functions is getting out of hand. A better solution is required that doesn't require so much duplication.
  • fix GLTF loader
    • handling of the materials
    • clean up code handling node/mesh recursion
    • comment fully
    • cleanup and/or refactor Mesh/Model to separate GLTF translation layer from generic data layer
  • add loading message as the model load is done - it takes a while
    • it turns out this is a bit tricky the way I planned. I added event sending support at the beginning of scene creation and at the end of the first render. Response to these events would be to disable and then re-enable the UI. This is not quite working. I'll leave it as is for now and revisit it later when perhaps I'll have a better idea how to do this - the main issue is the pointer-events:none styling which is not working as expected.

• First

  • document code - in progress
  • add CPU processing for matrix operations for debug and printing
  • add bounding box calculations

• add game controller support

  • very rudimentary and slightly clunky support is in place now

• add camera movement by controller

• fix -ve angle rotation operations

• add cube rotation

  • how does this differ from a flying camera ?

• refactor and simplify RubiksCube.updateLocations()

• add error logging handler

• handle window resize

• Consider use of VAO to stop have to bind vertexAttribPointers on every render call
