public Class EXTMultiDraw

extends Object
Class Inheritance
Imports
javax.annotation.*, java.nio.*, org.lwjgl.system.*
Processing multiple draw commands in sequence incurs measurable overhead within drivers due to repeated state checks and updates during dispatch. This extension enables passing the entire sequence of draws directly to the driver in order to avoid any such overhead, using an array of VkMultiDrawInfoEXT or VkMultiDrawIndexedInfoEXT structs with vkCmdDrawMultiEXT or vkCmdDrawMultiIndexedEXT, respectively. These functions could be used any time multiple draw commands are being recorded without any state changes between them in order to maximize performance.
