ARKit –渲染距离超过1000米的物体 [英] ARKit – Render objects further away than 1000 meters

问题描述

我正在尝试渲染远于1000的对象.

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)

从此此答案，我知道ARKit直接设置SCNCamera的projectionTransform.因此，无论如何，我是否要更改projectionTransform以便将对象渲染得更远?

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?

推荐答案

在ARKit_3.0/SceneKit_2020中，如果从ARCamera到3D模型的距离大于1000m SceneKit的着色器 猛烈地开始闪烁 ，并且大约在模型完全消失.

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.

您的ARCamera不会渲染应用程序的3D内容.此着色器的工件是SceneKit的渲染引擎问题.因此，您目前与此无关.
