C Specification
To bind an index buffer, along with its size, to a command buffer, call:
// Provided by VK_VERSION_1_4
void vkCmdBindIndexBuffer2(
VkCommandBuffer commandBuffer,
VkBuffer buffer,
VkDeviceSize offset,
VkDeviceSize size,
VkIndexType indexType);
or the equivalent command
// Provided by VK_KHR_maintenance5
void vkCmdBindIndexBuffer2KHR(
VkCommandBuffer commandBuffer,
VkBuffer buffer,
VkDeviceSize offset,
VkDeviceSize size,
VkIndexType indexType);
Parameters
-
commandBufferis the command buffer into which the command is recorded. -
bufferis the buffer being bound. -
offsetis the starting offset in bytes withinbufferused in index buffer address calculations. -
sizeis the size in bytes of index data bound frombuffer. -
indexTypeis a VkIndexType value specifying the size of the indices.
Description
size specifies the bound size of the index buffer starting from
offset.
If size is VK_WHOLE_SIZE then the bound size is from
offset to the end of the buffer.
If the maintenance6 feature is enabled,
buffer can be VK_NULL_HANDLE.
If buffer is VK_NULL_HANDLE and the nullDescriptor feature is enabled, every index fetched results in a
value of zero.
