Overview

An anaglyphic stereo rendering

This features adds support for anaglyphic stereo rendering. Each eye pass is rendered in a different color, but using the same frame buffer. Colored glasses provide the eye separation when viewing the superimposed images.

Implementation

Extending Channel::applyBuffer to use glColorMask to mask out the correct components for the current eye allow rendering as in quad-buffered stereo. The color mask is applied at the very end of the OpenGL pipeline, and therefore affects all operations, including glClearColor and the pixel operations used for stereo decomposition.

API

    class ColorMask
    {
    public:
        ColorMask() : red( true ), green( true ), blue( true ) {}
        bool red;
        bool green;
        bool blue;
    };

    const ColorMask& Channel::getDrawBufferMask() const;
