java.lang.Object

org.lwjgl.vulkan.AMDDrawIndirectCount

public class AMDDrawIndirectCount
extends java.lang.Object

This extension allows an application to source the number of draw calls for indirect draw calls from a buffer. This enables applications to generate arbitrary amounts of draw commands and execute them without host intervention.

Promotion to VK_KHR_draw_indirect_count

All functionality in this extension is included in VK_KHR_draw_indirect_count, with the suffix changed to KHR. The original type, enum and command names are still available as aliases of the core functionality.

Method Detail

vkCmdDrawIndirectCountAMD

public static void vkCmdDrawIndirectCountAMD(VkCommandBuffer commandBuffer,
                                             long buffer,
                                             long offset,
                                             long countBuffer,
                                             long countBufferOffset,
                                             int maxDrawCount,
                                             int stride)

See CmdDrawIndirectCountKHR.

Parameters:

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

buffer - the buffer containing draw parameters.

offset - the byte offset into buffer where parameters begin.

countBuffer - the buffer containing the draw count.

countBufferOffset - 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 - the byte stride between successive sets of draw parameters.

vkCmdDrawIndexedIndirectCountAMD

public static void vkCmdDrawIndexedIndirectCountAMD(VkCommandBuffer commandBuffer,
                                                    long buffer,
                                                    long offset,
                                                    long countBuffer,
                                                    long countBufferOffset,
                                                    int maxDrawCount,
                                                    int stride)

See CmdDrawIndexedIndirectCountKHR.

Parameters:

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

buffer - the buffer containing draw parameters.

offset - the byte offset into buffer where parameters begin.

countBuffer - the buffer containing the draw count.

countBufferOffset - 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 - the byte stride between successive sets of draw parameters.
