LiteFX::Rendering::Backends::VulkanGraphicsFactory::createIndexBuffer

Creates an index buffer, based on the layout.

Synopsis

Declared in <litefx/rendering.hpp>

[[dllimport]] virtual SharedPtr<IVulkanIndexBuffer> createIndexBuffer(
    String const& name,
    index_buffer_layout_type const& layout,
    ResourceHeap heap,
    UInt32 elements,
    ResourceUsage usage = ResourceUsage::Default,
    AllocationBehavior allocationBehavior = AllocationBehavior::Default) const = 0;

Description

An index buffer can be used by different RenderPipeline "RenderPipelines", as long as they share a common input assembler state.

The size of the buffer is computed from the element size index buffer layout, times the number of elements given by the elements parameter.

Return Value

The instance of the index buffer.

Parameters

Name	Description
name	The name of the buffer.
layout	The layout of the index buffer.
heap	The heap to allocate the buffer on.
usage	The intended usage for the buffer.
elements	The number of elements within the vertex buffer (i.e. the number of indices).
allocationBehavior	The behavior controlling what happens if currently there is not enough memory available for the resource.
