Is there a way to effectively remove the data stored in a BufferAttribute on the GPU using threejs?

When working with BufferAttributes in threejs, I encountered a scenario where I needed to delete a specific attribute without affecting others. The initial setup looked something like this:

 geometry.setAttribute("xxx", new THREE.BufferAttribute(new Float32Array(array), 3))

I tried deleting the attribute using the following code:

geometry.deleteAttribute("xxx")

However, even after setting the needUpdate value as true, it appeared that the data still remained in memory on the GPU.

This led me to explore ways of dynamically managing attributes within a geometry in threeJs.

Answer №1

Disposing of individual attributes is not feasible. The recommended approach is to invoke the dispose() method on the existing geometry object and subsequently generate a new one containing your revised set of buffer attributes.
