Program source code and data

This repository contains program source code and data to reproduce the experiments in Sections 5.2 and 5.3 of the paper entitled "An interactive sketch-based CAD interface realizing geometrical and topological editing across multiple objects based on fuzzy logic." By executing commands with JDK 16 on Windows, macOS, or Linux, the experiments are reproduced step by step.

Execution commands

In the directory where this README file is located, the following commands reproduce an experiment specified by <data name>. On each event of clicking the "Next" button in an opened window, the experiment is reproduced step by step.

• Windows

gradlew.bat run --args="--data=<data name>"

• macOS or Linux

./gradlew run --args="--data=<data name>"

<data name> can be set to one of the following strings:

• Fig24A
• Fig24B
• Fig24C
• Fig24D
• Fig24E
• Fig24F
• Fig24G
• Fig24H
• Fig24I
• Fig26
• Fig29
• Fig32

Drawn stroke data file format

A drawn stroke data file for each experiment contains a JSON array each element of which has a string named action and an object named drawingStroke.

• action is "Edit" or "Pick", where "Edit" is for sketching and "Pick" for tapping.
• drawingStroke has an array named paramPoints each element of which has an object named point and a number named param.
  • point has four numbers named x, y, z, and r.
    • x is an x-coordinate in pixel.
    • y is a y-coordinate in pixel.
    • z is always 0.0.
    • r is always 0.0.
  • param is a timestamp in second.

Parameter configuration file format

A parameter configuration file for each experiment contains a JSON object which has four numbers named width, height, baseGridSpacing, and baseGridFuzziness.

• width is a width of a viewport in pixel.
• height is a height of a viewport in pixel.
• baseGridSpacing is a base grid spacing in pixel, which is used by IFGS.
• baseGridFuzziness is a base grid fuzziness in pixel, which is used by IFGS.
