Package org.lwjgl.opengl
Class ARBParallelShaderCompile
java.lang.Object
org.lwjgl.opengl.ARBParallelShaderCompile
Native bindings to the ARB_parallel_shader_compile extension.
Compiling GLSL into implementation-specific code can be a time consuming process, so a GL implementation may wish to perform the compilation in a separate CPU thread. This extension provides a mechanism for the application to provide a hint to limit the number of threads it wants to be used to compile shaders, as well as a query to determine if the compilation process is complete.
Requires OpenGL 3.0

glMaxShaderCompilerThreadsARB
public static void glMaxShaderCompilerThreadsARB(int count) Application may use the following to hint to the driver the maximum number background threads it would like to be used in the process of compiling shaders or linking programs.An implementation may combine the maximum compiler thread request from multiple contexts in a share group in an implementation-specific way.
An application can query the current MaxShaderCompilerThreads()
count
by callingGetIntegerv
withpname
set toMAX_SHADER_COMPILER_THREADS_ARB
.- Parameters:
count
- the number of background threads. Acount
of zero specifies a request for no parallel compiling or linking and acount
of0xFFFFFFFF
requests an implementation-specific maximum.
