Computing Bounding Box After Moving Vertices in Shader
In ThreeJS, how can I update the bounding box/sphere after changing vertex positions in a shader?
Edit:
I should've clarified I'm using a particle buffer geometry and changing the vertex positions in the shader. I'm not calling geometry.attributes.position.needsUpdate = true;

If you are updating vertices in the shader, it is typical to do this, instead:
object.frustumCulled = false;

Oh. then there is no way for three to know the bounding box.. so you'll just have to set it to something yourself that best approximates where your particles might be.
