SketchRNN HTTP Web Server Service

Autocomplete sketches provided a model name & a list of drawn points via SketchRNN. It'll automatically draw sketches relative to the input data (i.e. no coordinate transformations required). Modified from the original example at https://github.com/MindExMachina/smartgeometry.

Input data format

• Model name
  • Available models to choose from are listed here: https://github.com/tobyloki/SketchRNNHttpServer/tree/master/services/sketch-rnn/lib/models
• List of points:
  • Each point contains:
    • (x, y) coordinate
    • (pen down, pen up, pen done) 1 hot encoding
    • Format: (x, y, up, down, done)
      • e.g. (20.0, 30.4, 1, 0, 0)
