An A-Frame component for runtime Constructive Solid Geometry (boolean mesh operations). It is based on ThreeCSG which it contains as a source copy in a slightly modified version.
<a-box csg-meshs="subtract: #sphere"></a-box>
<a-sphere id="sphere"></a-sphere>The component takes three optional properties:
- union
- subtract
- intersect
All properties work the same: They are Selector-Arrays to reference the corresponding meshs that will be unioned with / subtracted from / intersected with the meshs of this entity. The full object tree is considered.
Install and use by directly including the aframe-csg-meshs/index.js:
