Unity Depth Camera
Provides a quick and easy way to map depth texture values to RGB channels. I wrote it for feeding depth info to Unity Machine Learning Agents as visual observations.
You can define distance ranges by setting min and max values. Clamped distances are being mapped to the full 8-bit color range. Default depth values are flipped so that close objects are more saturated than farther-away ones.
Example settings

Red channel only.

Green channel only with inverted depth values.

One color channel per distance range, increases the total depth resolution compared to using a single channel.

Blue channel limited to foreground, mixed with source image’s red and green channels.

All channels limited to foreground, inverted.
