  (draw [socket] shader)

  Syncs code and parameters with glsl-view via OSC.

  • socket must be an osc/out~ or read from *oscout*
  • shader is a struct~ with
    • shader (str): GLSL source
    • uniforms: struct mapping uniform names to values
• shader (opdef):  – compile a GLSL shader with uniforms.

  #shader"code…"

  Syncs code and parameters with glsl-view via OSC.

  • code… is a template string that can contain ~-stream template substitutions that are used as follows:
    • str: substituted directly as GLSL
    • {type: str val: …}: reference to uniform of type type (instead of infered as follows)
    • num, bool: reference to uniform float/bool
    • num[I], bool[I]: reference to uniform vecI/bvecI
    • num[I][J]: reference to uniform matIxJ
• tsv-input (opdef):  – load a texture-share-vk texture source.

  (texture [socket] name [type])

• video (opdef):  – load a video texture source.

  (video [socket] name filename [type])
