vkCmdDispatchBase

Dispatch compute work items with non-zero base values for the workgroup IDs

To record a dispatch using non-zero base values for the components of WorkgroupId, call:

void vkCmdDispatchBaseKHR(
    VkCommandBuffer commandBuffer,
    uint32_t baseGroupX,
    uint32_t baseGroupY,
    uint32_t baseGroupZ,
    uint32_t groupCountX,
    uint32_t groupCountY,
    uint32_t groupCountZ);
  • commandBuffer is the command buffer into which the command will be recorded.
  • baseGroupX is the start value for the X component of WorkgroupId.
  • baseGroupY is the start value for the Y component of WorkgroupId.
  • baseGroupZ is the start value for the Z component of WorkgroupId.
  • groupCountX is the number of local workgroups to dispatch in the X dimension.
  • groupCountY is the number of local workgroups to dispatch in the Y dimension.
  • groupCountZ is the number of local workgroups to dispatch in the Z dimension.

When the command is executed, a global workgroup consisting of groupCountX × groupCountY × groupCountZ local workgroups is assembled, with WorkgroupId values ranging from [baseGroup*, baseGroup* + groupCount*) in each component. vkCmdDispatch is equivalent to vkCmdDispatchBase(0,0,0,groupCountX,groupCountY,groupCountZ).
