|
* A storage for USERCODE-PROVIDED parameters for GPU programs.
|
|
* Allows for fast updating and iteration of parameters.
|
|
* NOTE TO DRIVER IMPLEMENTORS: DO NOT USE FOR STORING COPIES
|
|
* OF HARDCODED DRIVER MATERIAL PARAMETERS OR DRIVER PARAMETERS!!!
|
|
* The 4-component alignment that is done in this storage
|
|
* class is necessary to simplify support for register-based
|
|
* assembly shaders, which require setting per 4 components.
