This Skill adds atmospheric perspective and visual depth to 3D scenes by simulating fog, making distant objects fade into a background color.
Apply the linear fog skill to your SDL GPU project by adding the provided HLSL code to your fragment shader and setting the fog uniforms.

To add distance-based fog to an SDL3 GPU rendering pipeline, integrate HLSL code snippets into your fragment shader and define uniform buffers for fog parameters like color, start and end distances, density, and mode to apply the effect after lighting calculations.
Supported fog modes for 3D rendering in HLSL include linear, exponential, and exponential-squared fog. These modes are applied in the fragment shader after lighting calculations to simulate atmospheric perspective by fading distant objects into a background color.
Yes, linear fog works with SDL GPU fragment shaders by applying provided HLSL code snippets after lighting calculations. You must set uniform buffer definitions for fog parameters including color, start and end distances, density, and the specific fog mode.
For 3D scene fog calculation, you need to define uniform buffers for fog parameters including color, start and end distances, density, and mode. These uniforms configure the HLSL fragment shader calculations for linear, exponential, or exponential-squared fog.
Use exponential or exponential-squared fog instead of linear fog in 3D rendering when you need density-based atmospheric perspective rather than distance-based fading. Exponential modes provide smoother fog transitions for hazy environments, while linear fog uses strict start and end distances.
