问题描述

如何获得立方体角的 4 个坐标?

How do I get the 4 coordinates for the corners of a cube?

推荐答案

如果您使用 CubeGeometry(宽度、高度、深度)并将立方体放置在某个位置，那么您的八个角位于

If you are using the CubeGeometry (width, height, depth) and you positioned the cube somewhere, then your eight corners are at

position.x + width/2, position.y + height/2, position.z + depth/2
position.x + width/2, position.y + height/2, position.z - depth/2
position.x + width/2, position.y - height/2, position.z + depth/2
position.x + width/2, position.y - height/2, position.z - depth/2
position.x - width/2, position.y + height/2, position.z + depth/2
position.x - width/2, position.y + height/2, position.z - depth/2
position.x - width/2, position.y - height/2, position.z + depth/2
position.x - width/2, position.y - height/2, position.z - depth/2
