轻量封装WebGPU渲染系统示例＜32＞- 若干线框对象(源码)

当前示例源码github地址:

https://github.com/vilyLei/voxwebgpu/blob/feature/rendering/src/voxgpu/sample/WireframeEntityTest.ts

当前示例运行效果:

此示例基于此渲染系统实现，当前示例TypeScript源码如下:

export class WireframeEntityTest {
	private mRscene = new RendererScene();
	initialize(): void {
 
		this.initEvent();
		this.initScene();
	}
	private initEvent(): void {
		const rc = this.mRscene;
		rc.addEventListener(MouseEvent.MOUSE_DOWN, this.mouseDown);
		new MouseInteraction().initialize(rc, 0, false).setAutoRunning(true);
	}
	private mouseDown = (evt: MouseEvent): void => {};
	private initScene(): void {
		const rc = this.mRscene;
 
		let axis = new AxisEntity();
		rc.addEntity(axis);
 
		let entities = [
			new SphereEntity(),
			new BoxEntity(),
			new CylinderEntity({ alignYRatio: 0.0 }),
			new CubeEntity({ cubeSize: 130 }),
			new TorusEntity({ radius: 110, axisType: 1 }),
			new PlaneEntity({ axisType: 1, extent: [-80, -80, 160, 160], doubleFace: true }),
			new ConeEntity({ alignYRatio: 0.0 })
		];
 
		let ls = entities;
		entities = [];
 
		// random sorting
		for (let i = 0, ln = ls.length; i < ln; ++i) {
			const k = Math.round(Math.random() * 888) % ls.length;
			entities.push(ls[k]);
			ls.splice(k, 1);
		}
 
		let radius = 300.0;
 
		for (let i = 0; i < entities.length; ++i) {
			let rad = (2.0 * Math.PI * i) / entities.length;
 
			let entity = entities[i].setAlbedo(new Color4().randomRGB(1.5, 0.1));
			entity.arm = [1.1, Math.random() * 0.95 + 0.05, Math.random() * 0.9 + 0.1];
			entity.transform.setPosition([radius * Math.cos(rad), 0, radius * Math.sin(rad)]);
			rc.addEntity(entity);
		}
 
		radius += 230;
		for (let i = 0; i < entities.length; ++i) {
			let rad = (2.0 * Math.PI * i) / entities.length + 0.5;
 
			let entity = entities[i].clone({ geometry: entities[i].geometry, doubleFace: true, wireframe: true });
			entity.transform.setPosition([radius * Math.cos(rad), 0, radius * Math.sin(rad)]);
			rc.addEntity(entity);
		}
	}
 
	run(): void {
		this.mRscene.run();
	}
}
