colormap#getGPUResources¶
Summary¶
colormap#getGPUResources returns the one-dimensional texture view and sampler used for GPU lookup. CPU-backed colormaps return a stable resource pair for each GPUDevice; external colormaps return their borrowed view and sampler and require the device used at construction.
Syntax¶
Colormap.getGPUResources(device: GPUDevice, queue: GPUQueue): ColormapGPUResources
const result = colormap.getGPUResources(device, queue);
Parameters¶
| Name | Type | Required | Description |
|---|---|---|---|
device |
GPUDevice |
Yes | Device that owns or will own the returned texture view and sampler. |
queue |
GPUQueue |
Yes | Queue used to upload a CPU-backed lookup table when first needed. |
Returns¶
ColormapGPUResources - Texture (or null for an external view), view, sampler, width, and filter.
