Detailed Description

VSG extension Compute shader scheduler node

This node allows the application to setup the invocation of a compute shader.

When traversed by a rendering action, this node launches one or more compute work groups. Each work group is processed by the current SoShaderProgram for the SoComputeShader stage.

See Compute Shader section of the OpenGL wiki for more information about the execution model of compute shaders.

FILE FORMAT/DEFAULT

    ComputeShaderScheduler {
    numWorkGroups 1 1 1
    policy EACH_FRAME
    }
