Time for action—rendering anaglyph stereo scenes
We are going to make use of OSG's internal anaglyph stereo mode to implement a simple and quick stereoscopic 3D effect. Before starting programming and rendering the scene, we have to prepare a pair of 3D red/cyan glasses to view the result correctly:
In most cases, the left eye of the glasses is red, and the right eye is cyan. This is the most commonly-used anaglyph effect, with limited color perception.
- Include the necessary headers:
#include <osgDB/ReadFile> #include <osgViewer/Viewer>
