# Deferred Shading Example

This is an example of deferred shading with gfx-rs. It demonstrates the use of render targets and uniform buffers. It requires GL-3.2 to run.

Two render targets are created: a geometry buffer and a result buffer.

Rendering happens in two passes:
First,  the terrain is rendered, writing position, normal and color to the geometry buffer.
Second, the lights are rendered as cubes. each fragment reads from the geometry buffer,
        light is applied, and the result is written to the result buffer.

The result buffer is then displayed.

Press 1-4 to show the immediate buffers. Press 0 to show the final result.
