Example¶

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const scene = wgpu.createScene();
const graph = wgpu.createNodeLink({
    nodePositions: new Float32Array([
        -0.5, 0.0, 0.0,
         0.5, 0.0, 0.0
    ]),
    edges: new Uint16Array([0, 1])
});
graph.visible = true;
scene.add(graph);
scene.traverseVisibleNodeLinks((link) => {
    link.opacity = 0.9;
});
