Sketch outputs/inputs

[funwithtriangles]

Sketches should be able to register outputs. These can be things such as:

• textures
• 3D objects
• strings

These outputs appear in a global list somewhere and can be linked to params. For example a sketch could output some mask texture that is then used by another sketch.

Could have the idea of "Auxillary Sketches" that don't live in a scene. They produce outputs, such as textures (e.g. vertex shader). These textures can be selected whenever a sketch has a texture as a param
