Next, we create methods to bind and unbind the render targets to the pipeline and
finally to clear the G-Buffer:
// Bind the render targets to the OutputMerger
public void Bind(DeviceContext1 context)
{
context.OutputMerger.SetTargets(DSV, 0,
new UnorderedAccessView [0], RTVs.ToArray());
}
// Unbind the render targets
public void Unbind(DeviceContext1 context)
{
context.OutputMerger.ResetTargets();
}
// Clear the render targets and depth stencil
public void Clear(DeviceContext1 context, Color background)
{
context.ClearDepthStencilView(DSV,
DepthStencilClearFlags.Depth |
DepthStencilClearFlags.Stencil, 1.0f, 0);
foreach (var rtv in RTVs)
context.ClearRenderTargetView(rtv, background);
}
This completes our generic
GBuffer
class. With this we can easily create new
G-Buffer layouts depending on the specific rendering requirements.
