    3 TODO features to add

    +
    +
      +
    • Partial region/frame repaint: when only one small object changed on +the scene, it would be faster to re-render that specific area. +
      • + +
    • Once partial rendering works, in would be easy to add multi-core +rendering support. So that each core renders it's own region of the +screen. +
      • + +
    • Antialiazing. Would improve text readability. If antialiazing is too +expensive for every frame, it could be used only for last frame +before animations become still and waiting for user input starts. +
      • + +
    • Render only visible polygons. +
        +
      • This would significantly reduce RAM <-> CPU traffic. +
        • + +
      • General algorithm description: +
          +
        • For each horizontal scanline: +
            +
          • sort polygon edges from left to right +
            • +
          • while iterating and drawing pixels over screen X axis (left to +right) track next appearing/disappearing polygons. +
              +
            • For each polygon edge update Z sorted active polygons list. +
              • +
            • Only draw pixel from the top-most polygon. +
                +
              • Only if polygon area is transparent/half-transparent add +colors from the polygons below. +
                • +
              +
              • +
            +
            • +
          +
          • +
        +
        • + +
      • As a bonus, this would allow to track which polygons are really +visible in the final scene for each frame. + +
          +
        • Such information allows further optimizations: + +
            +
          • Dynamic geometry simplification: +
              +
            • Dynamically detect and replace invisible objects from the +scene with simplified bounding box. +
              • + +
            • Dynamically replace boudnig box with actual object once it +becomes visible. +
              • +
            +
            • + +
          • Dynamically unload unused textures from RAM. +
