createGlyphField#computeBoundsFromCPUData¶
Summary¶
createGlyphField#computeBoundsFromCPUData derives local bounds from retained positions, scales, optional rotations, and the glyph geometry's local box. It is a no-op without retained positions/scales or instances and replaces prior bounds with computed bounds.
Syntax¶
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 } });
glyphField.computeBoundsFromCPUData();
console.log(glyphField.getLocalBounds().empty); // false
