GLDISPATCHCOMPUTE(3G)						   OpenGL Manual					     GLDISPATCHCOMPUTE(3G)

NAME

       glDispatchCompute - launch one or more compute work groups

C SPECIFICATION

       void glDispatchCompute(GLuint num_groups_x, GLuint num_groups_y, GLuint num_groups_z);

PARAMETERS

       num_groups_x
	   The number of work groups to be launched in the X dimension.

       num_groups_y
	   The number of work groups to be launched in the Y dimension.

       num_groups_z
	   The number of work groups to be launched in the Z dimension.

DESCRIPTION

       glDispatchCompute launches one or more compute work groups. Each work group is processed by the active program object for the compute
       shader stage. While the individual shader invocations within a work group are executed as a unit, work groups are executed completely
       independently and in unspecified order.	num_groups_x, num_groups_y and num_groups_z specify the number of local work groups that will be
       dispatched in the X, Y and Z dimensions, respectively.

ERRORS

       GL_INVALID_OPERATION is generated if there is no active program for the compute shader stage.

       GL_INVALID_VALUE is generated if any of num_groups_x, num_groups_y, or num_groups_z is greater than or equal to the maximum work-group
       count for the corresponding dimension.

ASSOCIATED GETS

       glGet() with argument GL_MAX_COMPUTE_WORK_GROUP_COUNT

NAME

       glGetUniformSubroutine - retrieve the value of a subroutine uniform of a given shader stage of the current program

C SPECIFICATION

       void glGetUniformSubroutineuiv(GLenum shadertype, GLint location, GLuint *values);

PARAMETERS

       shadertype
	   Specifies the shader stage from which to query for subroutine uniform index.  shadertype must be one of GL_VERTEX_SHADER,
	   GL_TESS_CONTROL_SHADER, GL_TESS_EVALUATION_SHADER, GL_GEOMETRY_SHADER or GL_FRAGMENT_SHADER.

       location
	   Specifies the location of the subroutine uniform.

       values
	   Specifies the address of a variable to receive the value or values of the subroutine uniform.

DESCRIPTION

       glGetUniformSubroutine retrieves the value of the subroutine uniform at location location for shader stage shadertype of the current
       program.  location must be less than the value of GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS for the shader currently in use at shader stage
       shadertype. The value of the subroutine uniform is returned in values.

ERRORS

       GL_INVALID_ENUM is generated if shadertype is not one of the accepted values.

       GL_INVALID_VALUE is generated if location is greater than or equal to the value of GL_ACTIVE_SUBROUTINE_UNIFORM_LOCATIONS for the shader
       currently in use at shader stage shadertype.

       GL_INVALID_OPERATION is generated if no program is active.
