Struct TextureResampler 

pub struct TextureResampler { /* private fields */ }

A compiled compute kernel that resamples a sampleable source texture into a destination storage texture using a hardware sampler.

Constructed once per (method, dst_format) pair via TextureResampler::new and reused across many dispatches.

Implementations

impl TextureResampler

pub fn new( ctx: &GpuContext, method: TextureFilterMethod, dst_format: TextureFormat, ) -> GpuResult<Self>

Construct a new texture resampler.

Parameters

• ctx — the GPU context that owns the device and queue.
• method — the filter mode (Nearest or Linear) applied by the sampler.
• dst_format — the storage texture format the kernel will write to. Must be one of Rgba32Float, R32Float, or Rgba8Unorm.

Errors

Returns GpuError::UnsupportedFormat when dst_format is not one of the supported destination formats.

pub fn method(&self) -> TextureFilterMethod

The filter mode this resampler was constructed with.

pub fn dst_format(&self) -> TextureFormat

The destination storage-texture format this resampler writes to.

pub fn dispatch( &self, ctx: &GpuContext, src_texture: &Texture, dst_texture: &StorageTextureBinding, ) -> GpuResult<()>

Dispatch the compute kernel, reading from src_texture and writing to dst_texture.

Errors

• Returns GpuError::UnsupportedFormat when the destination texture format does not match the resampler’s dst_format.
• Returns the underlying error if the device has been lost.
