Detailed Description

Base class for render objects to implement a stereo render function that draws to the left and right eye directly as enabled by.

const GLenum buffers[] = {GL_BACK_LEFT, GL_BACK_RIGHT};
     glDrawBuffers(2, buffers);

A fragment shader may then write to the left and right eye directly via

#version 440
 
layout(location = 0) out vec4 leftColor;
layout(location = 1) out vec4 rightColor;
 
void main (void)
{
        leftColor  = vec4(0,0,1,0);
        rightColor = vec4(1,0,0,0);
}

However, there is only one depth buffer in this setup, so the usage is limited. Use class MultiviewRenderable and multiview_render() for situations when a depth buffer is needed separatedly for the left and right eye.
