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 isVK_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.
