Visual Stimulation

BonZeb was built to interface with the Bonsai Shaders package to generate visual stimuli. The Bonsai Shaders package utilizes OpenGL for rendering visual graphics. Bonsai Shaders provide extensive flexibility for programming in OpenGL. All visual stimuli in BonZeb can be modified. Stimuli are generated using a TexturedQuad mesh and a Material shader configured with a vertex file and a fragment file.
