About mapping texture2d to datatexture on GPGPU

Hello everyone , I have a question to ask. The situation is that I have a gpgpu particle system with datatexture for velocity and position, and a simulation fuild layer . i want to ask about mapping texture2d from fuild sim to gpgpu particle system. Currently the mapping is correct at only 1 angle, if I use orbitcontrols the mapping will be wrong. In the gpgpu system, I get the texture coordinates using the normalized particle position. Is it possible to map accurately using orbitcontrols? Does anyone have a solution for mapping textures2d onto the gpgpu particle system?
