Renders color heightmaps of images.

Color Heightmap

A WebGL-powered application to render the color heightmap of an input image.

Input Image	Heightmap

Demo

Try the app yourself at https://fonzcastellanos.github.io/color-heightmap/.

Features

• Configurable height channel
  • Height channel is one of the channels of the RGB color model
• Configurable interpretation of vertex streams
  • Vertex streams are interpreted as one of the following geometric primitives:
    • Triangle strips
    • Triangles
    • Lines
    • Points
• Automatic camera positioning and orientation
  • Achieved using the radius and center of the heightmap's bounding sphere, which is found by an implementation of Ritter's bounding sphere algorithm
• Intuitive mouse-based camera control

Limitations

• Performance is an issue for large images. I intend to implement downscaling in the future.
• Camera view is awkward for some orientations of the heightmap achieved through mouse-based camera control.
• Targets browsers supporting ECMAScript 2015.
