我正在尝试使用SSAO后处理着色器渲染场景.没有任何错误,但我看不到使用和不使用SSAO传递渲染的场景之间的任何差异.我像这样初始化渲染器:
// Create WebGL Renderer
var renderParameters = { antialias: false, alpha: false, clearColor: 0xFFFFFF };
renderer = new THREE.WebGLRenderer(renderParameters);
renderer.autoClear = false;
renderer.setSize(viewportWidth, viewportHeight);
// Create render targets
renderTargetParametersRGB = { minFilter: THREE.LinearFilter, magFilter: THREE.LinearFilter, format: THREE.RGBFormat };
renderTargetParametersRGBA = { minFilter: THREE.LinearFilter, magFilter: THREE.LinearFilter, format: THREE.RGBAFormat };
depthTarget = new THREE.WebGLRenderTarget(width, height, renderTargetParametersRGBA);
colorTarget = new THREE.WebGLRenderTarget(width, height, renderTargetParametersRGB);
// The shader pass to draw the scene
var renderScenePass = new THREE.RenderPass(scene, camera);
// Copy to screen render …
