vkCmdSubpassShadingHUAWEI(3)

C Specification

A subpass shading dispatches a compute pipeline work with the work dimension of render area of the calling subpass and work groups are partitioned by specified work group size. Subpass operations like subpassLoad are allowed to be used.

To record a subpass shading, call:

// Provided by VK_HUAWEI_subpass_shading
void vkCmdSubpassShadingHUAWEI(
    VkCommandBuffer                             commandBuffer);

Parameters

commandBuffer is the command buffer into which the command will be recorded.

Description

When the command is executed, a global workgroup consisting of ceil (render area size / local workgroup size) local workgroups is assembled.
