vkCmdBindTransformFeedbackBuffers2EXT(3)

C Specification

To bind transform feedback memory ranges to a command buffer for use in subsequent drawing commands, call:

// Provided by VK_KHR_device_address_commands with VK_EXT_transform_feedback
void vkCmdBindTransformFeedbackBuffers2EXT(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    firstBinding,
    uint32_t                                    bindingCount,
    const VkBindTransformFeedbackBuffer2InfoEXT* pBindingInfos);

Parameters

commandBuffer is the command buffer into which the command is recorded.
firstBinding is the index of the first transform feedback binding whose state is updated by the command.
bindingCount is the number of transform feedback bindings whose state is updated by the command.
pBindingInfos is a pointer to an array of VkBindTransformFeedbackBuffer2InfoEXT structures specifying the ranges of memory to be used to capture transform feedback data.

Description

Element i of pBindingInfos replaces the current state for the transform feedback binding firstBinding + i, for i in [0,bindingCount).
