Report On Pure Data and Gem

The document describes a Pure Data and Gem project that adds interactive features to 3D objects, including light and color controls. The project uses Gem to perform graphical processing within Pure Data. It creates a window to display 3D objects using "gemwin" and "gemhead". It then adds a point light source that can be rotated and turned on/off. Finally, it implements color controls, providing options for green, grey, and yellow colors. The purpose is to create an interactive 3D experience that allows users to manipulate light and colors.
