Expand description

The bus over which CPU and GPU versions of the GPU cache get synchronized.

Variants§

§

PixelBuffer

PBO-based updates, currently operate on a row granularity. Therefore, are subject to fragmentation issues.

Fields

§rows: Vec<CacheRow>

Per-row data.

§

Scatter

Shader-based scattering updates. Currently rendered by a set of points into the GPU texture, each carrying a GpuBlockData.

Fields

§program: Program

Special program to run the scattered update.

§vao: CustomVAO

VAO containing the source vertex buffers.

§buf_position: VBO<[u16; 2]>

VBO for positional data, supplied as normalized u16.

§buf_value: VBO<GpuBlockData>

VBO for gpu block data.

§count: usize

Currently stored block count.
