forge-linear-fog

What problem does it solve?

Adds depth-based distance fog to any SDL GPU scene to simulate atmospheric perspective and improve depth cues by fading distant objects toward a fog color.

Core Features & Use Cases

• Distance-based fog: supports linear, exponential, and exponential-squared modes to fade distant geometry toward a fog color.
• Shader integration: designed to be appended to an existing fragment shader pipeline and blended after lighting.
• Practical use cases: enhance realism for outdoor scenes, reduce Z-fighting visibility at far distances, and simulate haze or weather effects.

Quick Start

Add the fog uniform block (fog_color, fog_start, fog_end, fog_density, fog_mode) and implement the depth-based fog calculation in your fragment shader to blend with the lit color after lighting.
