Struct GpuPixelBuffer 

pub struct GpuPixelBuffer {
    pub pixels: Vec<f32>,
    pub width: u32,
    pub height: u32,
    pub frame: u32,
    pub seed: u32,
    pub using_gpu: bool,
}

GPU pixel buffer for demo rendering

When gpu feature is enabled, this uses actual GPU compute via trueno/wgpu. Otherwise falls back to CPU implementation.

Fields

pixels: Vec<f32>

Pixel data (0.0 = uncovered, 1.0 = fully covered)

width: u32

Buffer width

height: u32

Buffer height

frame: u32

Current frame number

seed: u32

RNG seed

using_gpu: bool

Whether GPU is being used

Implementations

impl GpuPixelBuffer
