Purpose

The SoShowDepthBuffer is used to render the current depth buffer to the screen.

Its main purpose is to visually debug the depth buffer.

Usage

Place the module into any Open Inventor scene. It will render the depth buffer as it appears when the GLRenderAction of the module is called, so you must position it as the last node in the scene to capture the complete depth buffer.

Tips

The module requires OpenGL 2.0 and GLSL shader support to work.
