不同 iPhone 上的 ARKit [英] ARKit on different iPhones

问题描述

我一直在寻找 ARKit(特别是 ARSCNView)是否在所有设备上显示相同的屏幕/视图/场景大小的答案.我只有一部 iPhone XS，因此无法在其他设备上测试我的 ARKit 应用.

I've been looking for an answer to whether ARKit, specifically ARSCNView, shows the same screen/view/scene size on all devices. I only have an iPhone XS so I am unable to test my ARKit app on other devices.

目前我正在用 SpriteKit 的 SKScene 覆盖它，在 SpriteKit 中有 2 种不同尺寸的所有设备都可以运行.

Currently I am overlaying it with an SKScene from SpriteKit, and in SpriteKit there are 2 different sizes all devices run on.

通过打印语句，我已经能够通过前置摄像头找到它，从而在屏幕上呈现我的脸，并用 SKScene 覆盖它，屏幕/视图/场景/等的大小是 <强>375x812.

Through print statements I've been able to find that with the front-facing camera, thus presenting my face on-screen, and overlaying it with an SKScene, that the size of the screen/view/scene/etcetc is 375x812.

有没有人知道 ARKit + SpriteKit 覆盖的所有设备是否都具有相同的尺寸?

Does anyone happen to know if all devices present the same size with ARKit + SpriteKit overlay?

推荐答案

当然不同的 iPhone 机型呈现不同的分辨率.iPhone 的 screen size 和 viewport size 之间存在很大差异.看看这张表.在某些情况下，viewport size 是 screen size 的 1/9，有时是 – 1/4.但是，某些模型具有相同的屏幕尺寸和视口尺寸.

Of course different iPhone models present different resolutions. There's a big difference between iPhone's screen size and viewport size. Look at this table. In some cases viewport size is 1/9 of screen size, sometimes – 1/4. Though, some models have identical screen size and viewport size.
