问题描述
限时送ChatGPT账号..是否可以在three.js中删除或切掉形状的部分?
例如,如果我制作了一个 CylinderGeometry 并想将它的前部剃掉",这样前部是平的,而后部是弯曲的,就像一个半圆柱体.这可能吗?
我需要能够在圆柱体的正面和背面做到这一点,所以只有侧面是弯曲的.
解决方案这是可能的.你可以自己处理三角形,或者使用布尔运算和像 和此处提供一些与操纵几何体相关的建议.
还有其他 算法网格可以移植,但这取决于你需要这个东西有多简单或复杂.
Is it possible to remove or cut away sections of shapes in three.js?
For example if I made a CylinderGeometry and wanted to "shave" the front of it away, so that the front was flat and the back was curved, like a half cylinder. Is this possible?
I need to be able to do it to the front and back of a cylinder, so just the sides are curved.
解决方案It is possible. You can deal with triangles yourself, or use Boolean operations with a library like Constructive Solid Geometry to do mesh subtraction.
Have a look here and here for some suggestions related to manipulating geometry.
There are other algorithms to slice a mesh that could be ported over, but it depends how simple or complex you need this thing to be.
