添加滤镜效果

接口说明

以下仅列出本指南示例代码中调用的部分主要接口：

开发步骤

1. 首先从项目根目录进入/src/main/ets/entryability/EntryAbility.ets文件，导入空间建模模块。

   import { Scene, RenderContext } from '@kit.ArkGraphics3D';
   import { spatialRender } from '@kit.SpatialReconKit';
   import { RenderingPipelineType } from '@ohos.graphics.scene'

2. 加载当前场景的上下文。

   let renderContext: RenderContext | null = Scene.getDefaultRenderContext();

3. 调用滤镜接口。

   if (renderContext != null) {
     renderContext.loadPlugin(spatialRender.GSPlugin.PLUGIN_ID);
     Scene.load().then(async (scene: Scene) => {
       let rf = scene.getResourceFactory();
       let effect : spatialRender.RetroEffect =
         await rf.createEffect({ effectId: spatialRender.GSPlugin.RETRO_EFFECT_ID }) as spatialRender.RetroEffect;
       let camera = await rf.createCamera({ name: "gsCam", path: "//gsCam" }, { renderingPipeline: RenderingPipelineType.FORWARD });
       camera.effects.append(effect)
     });
   }
