Module storage_texture 

Storage-texture output kernel support for OxiGDAL GPU.

This module enables compute shaders to write their output directly to a 2-D storage texture (WGSL texture_storage_2d<format, write>), bypassing the round-trip to a CPU-visible staging buffer. The resulting texture lives on the GPU and can be consumed by subsequent render passes, image-processing pipelines, or downloaded via read_texture_to_vec_f32 when the host needs the data.

Typical workflow

1. Create a storage texture with new_storage_texture.
2. Build a compute kernel from WGSL source with build_storage_texture_kernel.
3. Upload input data as a GpuBuffer using the standard buffer API.
4. Execute the kernel with StorageTextureKernel::dispatch_to_texture.
5. Optionally download results with read_texture_to_vec_f32.

Supported formats

wgpu::TextureFormat	WGSL format string
Rgba32Float	rgba32float
Rgba8Unorm	rgba8unorm
R32Float	r32float

Other formats are rejected by new_storage_texture with GpuError::UnsupportedFormat.

Structs

StorageTextureBinding

A 2-D GPU texture created with STORAGE_BINDING | COPY_SRC usage.

StorageTextureKernel

A compiled compute kernel that writes its output to a storage texture.

Functions

build_storage_texture_kernel

Compile a WGSL compute shader into a StorageTextureKernel.

is_supported_storage_format

Returns true if format is accepted by new_storage_texture.

make_storage_texture_shader_source

Generate default WGSL source for a kernel that copies a flat f32 input buffer into a 2-D storage texture.

new_storage_texture

Create a new 2-D storage texture on the GPU.

read_texture_to_vec_f32

Copy a storage texture to host memory, returning a Vec<f32>.
