`textureDimensions()`

Function in Builtins

Texture extent in texels, as a vec2<u32>.

import { textureDimensions } from 'typeshade'

The signature, the description and the examples come from the compiler's own source at commit 26de7be8.

Syntax

const textureDimensions: (
  tex: ReadonlyNode<TextureLoad2dKey | TextureLoadArrayKey>,
) => Node<"vec2<u32>">

Parameters

tex ReadonlyNode<TextureLoad2dKey | TextureLoadArrayKey>

Return value

Node<'vec2<u32>'>

Description

A 2D array texture reports its width and height the same way; the layer count is the separate textureNumLayers query. An integer texture is accepted too, since an extent does not depend on the texel element. On GLSL ES 3.00 the ivec3 that textureSize returns for an array is truncated to the two extent components. Bind the result with Let when it is read more than once per invocation.

Targets

Target	Support	Notes
WGSL (WebGPU)	Supported	`textureDimensions(tex)`.
GLSL ES 3.00 (WebGL2)	Supported	`uvec2(textureSize(tex, 0))`.
CPU oracle	Stub	The oracle has no texture memory and no neighbouring fragments. The call throws unless the module was compiled with `{ gpuStubs: true }`, which returns a placeholder.
