在 SceneKit 中的平面上重复纹理 [英] Repeating a texture over a plane in SceneKit

问题描述

我有一个 32x32 .png 图像，我想在 SCNPlane 上重复该图像.我得到的代码(见下文)导致图像被拉伸以适应平面的大小，而不是重复.

I have a 32x32 .png image that I want to repeat over a SCNPlane. The code I've got (See below) results in the image being stretched to fit the size of the plane, rather than repeated.

代码:

let planeGeo = SCNPlane(width: 15, height: 15)

let imageMaterial = SCNMaterial()
imageMaterial.diffuse.contents = UIImage(named: "art.scnassets/grid.png")

planeGeo.firstMaterial = imageMaterial

let plane = SCNNode(geometry: planeGeo)

plane.geometry?.firstMaterial?.diffuse.wrapS = SCNWrapMode.repeat
plane.geometry?.firstMaterial?.diffuse.wrapT = SCNWrapMode.repeat

推荐答案

我修复了它.好像图像被放大了.如果我执行 imageMaterial.diffuse.contentsTransform = SCNMatrix4MakeScale(32, 32, 0)，图像会重复.

I fixed it. It seems like the image was zoomed in. If I do imageMaterial.diffuse.contentsTransform = SCNMatrix4MakeScale(32, 32, 0), the image repeats.
