toy project rendering 3D with math and shader, without a framework. named with "Triadica sebifera".

• Live Demo https://r.tiye.me/Quatrefoil-GL/triadica-space/ URL Parameters:
  • effects=on/off
  • dev=release/dev
  • hide-tabs=true/false
  • tab=axis/lamps/...
• Docs https://github.com/triadica/guidebook/
• DevLog videos(Chinese)
• Artworks with Triadica

For example:

object $ {} (:draw-mode :lines)
  :vertex-shader $ inline-shader "\"shape.vert"
  :fragment-shader $ inline-shader "\"shape.frag"
  :points $ map geo
    fn (p)
      -> p
        map $ fn (i)
          * i 40
        &v   $ [] 400 300 -1200
  :indices indices
  :hit-region $ {}
    :position $ [] 400 300 -1200
    :radius 20
    :on-hit $ fn (e d!)
      js/alert "\"hit on cube"
    :on-mousedown $ fn (e d!)
    :on-mousemove $ fn (e d!)
    :on-mouseup $ fn (e d!)

• :draw-mode supports :lines, :triangles, :line-strip
• *-shader is a text of shader string
• :points
• :indices, optional, list of numbers
• :attributes, a list of points or floats
• :hit-region, enables click detection
