WebGL & GLSL abstraction layer.

Largely declarative WebGL 1.0 / 2.0 abstraction layer, partially ported & updated from Clojure/ClojureScript versions of thi.ng/geom.


  • Extensive set of WebGL related types & interfaces
  • Declarative shader definition
    • option to fully define shaders in TypeScript and transpile to GLSL (via @thi.ng/shader-ast)
    • attribute, varying, uniform & output type declarations via a simple config object
    • GLSL code generation of data type declarations
    • automatic support for GLSL ES 1.0 & 3.0
    • optional layout attrib layout support for GLES 3 (WebGL2)
    • automatic & typed uniform setters
    • pre-declared desired GL draw state flags / settings
    • customizable shader presets
  • Declarative geometry, attribute & index buffer specs
  • Declarative instancing (always available in WebGL2, or via ANGLE ext in WebGL1)
  • Texture wrapper, declarative config
  • Comprehensive texture format info (channels, strides, renderable, filterable etc.)
  • FBO support with multiple attachments & render buffers
  • Multi-pass shader pipeline (e.g. for GPGPU tasks)
  • Pixel reading from main color buffer and textures
  • Geometry & texture generators
  • WebGL extension helpers & semi-automatic extension enabling
  • WebGL canvas creation / setup
