遮挡效果

本段描述摘自 https://developers.google.cn/ar/develop/depth

遮挡是深度API的应用之一。
遮挡（即准确渲染虚拟物体在现实物体后面）对于沉浸式 AR 体验至关重要。
参考下图，假设场景中有一个Andy，用户可能需要放置在包含门边有后备箱的场景中。渲染时没有遮挡，Andy 会不切实际地与树干边缘重叠。如果您使用场景的深度来了解虚拟 Andy 相对于木箱等周围环境的距离，就可以准确地渲染 Andy 的遮挡效果，使其在周围环境中看起来更逼真。

使用ARFoundation

ARFoundation中提供了AROcclusionManager脚本，在AR Session Origin的AR Camera对象上挂载该脚本即可。在场景启动后，会自动启用虚实遮挡（当然Depth Mode 不能选择的是disable）。

AROcclusionManager脚本内容如下：

使用EQ-R实现

EQ-R

简介

EQ-Renderer是EQ基于sceneform（filament）扩展的一个用于安卓端的三维AR渲染器。

主要功能

它包含sceneform_v1.16.0中九成接口（剔除了如sfb资源加载等已弃用的内容），扩展了视频背景视图、解决了sceneform模型加载的内存泄漏问题、集成了AREngine和ORB-SLAM3、添加了场景坐标与地理坐标系（CGCS-2000）的转换方法。

注：由于精力有限，文档和示例都不完善。sceneform相关请直接参考谷歌官方文档，扩展部分接口说明请移步git联系。

使用示例

需要在安卓清单中添加其值设为“com.google.ar.core.depth>

接口调用

在使用ARSceneLayout 创建AR布局控件时，在适当的地方修改深度遮挡模式即可，示例如下。

ARSceneLayout layout = new ARSceneLayout(this);//使用普通3d视图
layout.getSceneView.getCameraStream()setDepthOcclusionMode（DepthOcclusionMode.DEPTH_OCCLUSION_ENABLED);

实现方式

获取深度图和相机帧，在着色器中根据深度数据处理。

EQ-R基于filament

filament材质如下：

material {name : depth,shadingModel : unlit,blending : opaque,vertexDomain : device,parameters : [{type : samplerExternal,name : cameraTexture},{type : sampler2d,name : depthTexture},{type : float4x4,name : uvTransform}],requires : [uv0]
}fragment {void material(inout MaterialInputs material) {prepareMaterial(material);material.baseColor.rgb = inverseTonemapSRGB(texture(materialParams_cameraTexture, getUV0()).rgb);vec2 packed_depth = texture(materialParams_depthTexture, getUV0()).xy;float depth_mm = dot(packed_depth, vec2(255.f, 256.f * 255.f));vec4 view = mulMat4x4Float3(getClipFromViewMatrix(), vec3(0.f, 0.f, -depth_mm / 1000.f));float ndc_depth = view.z / view.w;gl_FragDepth = 1.f - ((ndc_depth + 1.f) / 2.f);}
}vertex {void materialVertex(inout MaterialVertexInputs material) {material.uv0 = mulMat4x4Float3(materialParams.uvTransform, vec3(material.uv0.x, material.uv0.y, 0.f)).xy;}
}

示例应用

之前基于Android(Java)做过的示例应用。
