Experimental:GLSL POP

Summary

This POP allows you to modify input attributes with GLSL. It works on a single attribute class at a time, Points, Verts or Primitives, and doesn't allow to change the number of input elements (Points, Verts or Primitives).

Refer to the Write GLSL POPs article for more info on using this POP.

TDSimplexNoise() simplexnoise - - Pick between Performance vs Quality Simplex noise. Performance mode picks the existing TDSimplexNoise(). Quality noise reduces certain artifacts and axis alignment issues with the existing simplex noise at the cost of speed.
  • Performance performance - Performant noise.
  • Quality quality - Quality noise.

Extra Information for the GLSL POP can be accessed via an Info CHOP.

Common POP Info Channels

Common Operator Info Channels

  • total_cooks - Number of times the operator has cooked since the process started.
  • cook_time - Duration of the last cook in milliseconds.
  • cook_frame - Frame number when this operator was last cooked relative to the component timeline.
  • cook_abs_frame - Frame number when this operator was last cooked relative to the absolute time.
  • cook_start_time - Time in milliseconds at which the operator started cooking in the frame it was cooked.
  • cook_end_time - Time in milliseconds at which the operator finished cooking in the frame it was cooked.
  • cooked_this_frame - 1 if operator was cooked this frame.
  • warnings - Number of warnings in this operator if any.
  • errors - Number of errors in this operator if any.
