I’m designing a webapp that is supposed to be an AR environment on your phone, to be viewed with something like Google Cardboard, but I am having an issue that the segmentPointer object that is meant to appear when clicking on an object is not.
I’ve checked the geometry displays correctly in a sandbox, and when I change it to a 3d object rather than shapeGeometry it does display, but I cannot figure out why it is not displaying how I want it to.
The project is at https://voxelverse.jackgreenearth.org/, and the code is quite long, but it is here to read in its totality below as it might need the whole context to discover the error. I’ve tried myself looking through the code, and I’ve tried searching the web and asking LLMs, but I couldn’t figure it out, so please help me, fellow humans.
