Unigine::CPUShaderCallable Class
| Header: | #include <UnigineThread.h> |
CPUShaderCallable is a template class that provides a simplified way to execute custom multithreaded logic using the CPUShader class.
Typically, to use a CPUShader, you need to inherit from the base CPUShader class and manually implement the process() method. However, CPUShaderCallable allows you to pass in the processing logic and optional cleanup logic directly as function objects without writing a custom class or managing inheritance.
It also supports an internal shared state that is accessible from all threads and can be cleaned up automatically after execution.
Template Parameters:
- State - user-defined type that stores shared state between threads.
- Process - function called per thread.
Signature: void(int thread_num, int num_threads) - Destroy - optional function called once after all threads are finished.
Signature: void(State state)
