C Specification
To bind an index buffer, along with its size, to a command buffer, call:
// Provided by VK_KHR_maintenance5
void vkCmdBindIndexBuffer2KHR(
VkCommandBuffer commandBuffer,
VkBuffer buffer,
VkDeviceSize offset,
VkDeviceSize size,
VkIndexType indexType);
Parameters
-
commandBuffer
is the command buffer into which the command is recorded. -
buffer
is the buffer being bound. -
offset
is the starting offset in bytes withinbuffer
used in index buffer address calculations. -
size
is the size in bytes of index data bound frombuffer
. -
indexType
is 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.
