createGlyphField#getColormapForBinding¶
Summary¶
createGlyphField#getColormapForBinding returns an existing Colormap, resolves a built-in name, or returns a grayscale texture fallback for "custom" because custom stops travel in uniforms.
Syntax¶
Returns¶
The borrowed Colormap used for texture binding.
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const glyphField = wgpu.createGlyphField({ instanceCount: 1, positions: new Float32Array([0, 0, 0, 0]), rotations: new Float32Array([0, 0, 0, 1]), scales: new Float32Array([1, 1, 1, 0]), attributes: new Float32Array([0.5, 0, 0, 0]), scaleTransform: { mode: "linear", domainMin: 0, domainMax: 1 } });
const colormap = glyphField.getColormapForBinding();
console.log(colormap === wgpu.colormap.viridis()); // true
