ARKit – 渲染 1000 米以外的物体 [英] ARKit – Render objects further away than 1000 meters

问题描述

我正在尝试渲染比 1000 更远的对象.

let box = SCNBox(width: 500, height: 500, length: 500, chamferRadius: 0)让 boxNode = SCNNode(geometry: box)boxNode.position = SCNVector3(0, 0, -2000)sceneView.scene.rootNode.addChildNode(boxNode)

从这个

您的 ARCamera 不呈现应用程序的 3D 内容.这个着色器的工件是 SceneKit 的渲染引擎问题.所以，您目前与此无关.

I'm trying to render objects further away than 1000.

let box = SCNBox(width: 500, height: 500, length: 500, chamferRadius: 0)
let boxNode = SCNNode(geometry: box)
boxNode.position = SCNVector3(0, 0, -2000)
sceneView.scene.rootNode.addChildNode(boxNode)

From this this answer I know that ARKit directly sets SCNCamera's projectionTransform. So is there anyway I change this projectionTransform in order to render objects further away?

解决方案

In ARKit_3.0/SceneKit_2020, if a distance from ARCamera to 3D model is greater than 1000m SceneKit's shader violently begins flickering and approximately at 1600m model disappears completely.

Your ARCamera doesn't render application's 3D content. This shader's artifact is SceneKit's rendering engine issue. So, you have nothing to do with that at the moment.
