Loading… please wait.

## C Specification

To record an indirect mesh tasks drawing command with the draw count sourced from a buffer, call:

    // Provided by VK_NV_mesh_shader with VK_KHR_draw_indirect_count or VK_VERSION_1_2
    void vkCmdDrawMeshTasksIndirectCountNV(
        VkCommandBuffer                             commandBuffer,
        VkBuffer                                    buffer,
        VkDeviceSize                                offset,
        VkBuffer                                    countBuffer,
        VkDeviceSize                                countBufferOffset,
        uint32_t                                    maxDrawCount,
        uint32_t                                    stride);

## Parameters

- `commandBuffer` is the command buffer into which the command is recorded.

- `buffer` is the buffer containing draw parameters.

- `offset` is the byte offset into `buffer` where parameters begin.

- `countBuffer` is the buffer containing the draw count.

- `countBufferOffset` is the byte offset into `countBuffer` where the draw count begins.

- `maxDrawCount` specifies the maximum number of draws that will be executed. The actual number of executed draw calls is the minimum of the count specified in `countBuffer` and `maxDrawCount`.

- `stride` is the byte stride between successive sets of draw parameters.

## Description

`vkCmdDrawMeshTasksIndirectCountNV` behaves similarly to vkCmdDrawMeshTasksIndirectNV except that the draw count is read by the device from a buffer during execution. The command will read an unsigned 32-bit integer from `countBuffer` located at `countBufferOffset` and use this as the draw count.
