Program for drawing objects, text, and images on an oscilloscope using audio output.

This allows for 3D rendering of .obj files, .svg images, and .txt files.

Lots of this code was built as part of a 24hr hackathon: IC Hack 20. The original repository can be found here: https://github.com/wdhg/ICHack20 It won 'Best Newcomers Prize' at the event.

Video Demonstration

Current Features

• Render .obj files on an oscilloscope
• Render .svg files
• Render text
• Rotation of objects
• Scaling image
• Translating image
• GUI for controlling renderer

Proposed Features

• Tune and transpose audio output
• Support rendering of multiple objects
• Saving pre-rendered frames to file for later loading
• Saving audio output to file
• (long term) Keyframing/animating objects and camera

Usage

Using osci-render is very easy; run the program and choose the file you would like to render, and it will output as audio to visualise on your oscilloscope.

By default, the program loads the cube.obj example. If this is working, you're good to go and should be able to load your own objects, files, or images!

Control the output using the sliders and text boxes provided. Currently the following can be controlled:

• Translation and speed of translation of the output
• Weight of the lines drawn
• Rotation speed
• Scale of the image

There are some additional controls for .obj files:

• Focal length of camera
• Position of camera

Building

All dependencies are specified in the pom.xml file. Cloning this repo and using IntelliJ with Maven should make building a painless process.
