I am programatically generating a mesh using buffergeometry but I’m having issues when viewing the rendered output. The mesh generated with wireframe material seem to be different when wireframe is set to false.
What do you think is causing this issue?
I am using Three JS version 98. Also tried it with other versions but problem still happens
Here’s a sample pen for the problem
You indices are correct actually. So is the rest of logic, to a certain extent.
The problem is that you are setting the geometry indices wrong. If you replace
geometry.setIndex(new THREE.BufferAttribute(new Uint8Array(indices), 3) );
geometry.setIndex( indices );
You can see that it renders the full quad properly.
You’re right. Thanks.
Although, the docs said it’s accepting BufferAttribute as a parameter.
You are absolutely correct, because it does. Changing the itemSize to 1, solves the issue as well.
setIndex() does internally. It checks if it’s a regular Array typed parameter, if it is… It converts to a BufferAttribute with itemSize 1.
