  1. You can build a tesseract wireframe by extending the same edge-construction rules from a square to a cube and then to 4D, which yields 16 vertices and 32 edges.
  2. Rotations in four dimensions are still planar operations that act on pairs of axes, so animations come from applying familiar 2D rotation formulas to axis pairs like XZ or Z🌀.
  3. There are many ways to project 4D to 2D with different tradeoffs—cavalier, cabinet, isometric, perspective, and fisheye—and a mixed approach (isometric for XYZ plus perspective or fisheye for the fourth axis) gives the clearest, most informative views.

  1. By using gl_FragData[0-3], you can output 4 separate fragment colors to up to 4 surfaces with one draw call
  2. Multiple Render Targets have various applications like deferred rendering, unique object IDs, and depth maps in 2D or 3D contexts
  3. Consider limitations with MRTs, like compatibility with platforms, VRAM usage, and controlling fragment outputs independently

  1. Using raymarching for rendering buildings can simplify complex fractal generation
  2. Deferred rendering can be utilized to optimize lighting workload by rendering lights onto surfaces
  3. Implementing HDR tone mapping can enhance color accuracy and brightness transitions in the game graphics

  1. Signed Distance Functions (SDFs) are useful for creating shapes like circles and boxes in shaders.
  2. SDFs allow for easy anti-aliasing and adding outlines to shapes in shaders.
  3. SDFs are versatile and can be used for various effects like glows, shadows, and direct lighting in shaders.
