Struct FogConfig 

pub struct FogConfig {
    pub color: Rgb565,
    pub near: u32,
    pub far: u32,
}

Depth epsilon for Z-buffer comparison to prevent Z-fighting

When triangles are nearly coplanar or edge-on to the camera, floating-point precision errors can cause depth values to be extremely close, leading to flickering (Z-fighting). This epsilon provides a small bias that helps new pixels pass the depth test when they are very close to existing ones.

Value: 128 in 16.16 fixed-point format = 0.00195 in floating-point Tuned for typical embedded graphics scenarios. Increase if Z-fighting persists, decrease if you notice incorrect depth ordering on distant objects.

Tuning guide:

• More Z-fighting? Increase this value (256, 512, etc.)
• Incorrect depth ordering? Decrease this value (64, 32, etc.)
• Adjust camera near/far planes for better depth precision distribution Configuration for depth-based fog effect

Fields

color: Rgb565

Fog color to blend towards

near: u32

Near plane distance (fixed-point 16.16 format)

far: u32

Far plane distance (fixed-point 16.16 format)

Implementations

impl FogConfig

pub fn new(color: Rgb565, near: f32, far: f32) -> Self

Create a new fog configuration

Arguments

• color - The fog color
• near - Near distance (depth values closer than this have no fog)
• far - Far distance (depth values farther than this are fully fogged)

pub fn apply(&self, base_color: Rgb565, depth: u32) -> Rgb565

Apply fog effect to a color based on depth
