Another Data Binding error in CG

Texturemanager: getgausstf (gaussparam); this function reads the gaussparam parameter by reference and binds it to a certain CG parameter.

However, if the function is executed after cgglbindprogram (XXX), the gaussparam cannot be obtained. I started to think it was a reference problem, and then changed it to pass the value. The same error. Finally, we found that the function must be executed before cgglbindprogram. ------------------------------------------ The above statements are incorrect, not the root of the problem! The key is texturemanager: getgausstf (gaussparam) gaussparam involves Address allocation. If the gaussparam address is assigned by texturemager, it will automatically expire during the call. Must be allocated before calling this function!
