C Specification

The actual generation of commands as well as their execution on the device is handled as single action with:

// Provided by VK_NV_device_generated_commands
void vkCmdExecuteGeneratedCommandsNV(
    VkCommandBuffer                             commandBuffer,
    VkBool32                                    isPreprocessed,
    const VkGeneratedCommandsInfoNV*            pGeneratedCommandsInfo);

Parameters

  • commandBuffer is the command buffer into which the command is recorded.

  • isPreprocessed represents whether the input data has already been preprocessed on the device. If it is VK_FALSE this command will implicitly trigger the preprocessing step, otherwise not.

  • pGeneratedCommandsInfo is a pointer to an instance of the VkGeneratedCommandsInfoNV structure containing parameters affecting the generation of commands.
