Member Function Documentation

OnApplicationTick()

void Examples::Win32_ScreenCaptureApp::OnApplicationTick ( )

inlineoverrideprivatevirtual

Action to take on every application tick.

Note

This is run on the main thread, i.e. the calling thread of RunForever. No synchronization is performed on a per-frame basis. You may want to use WaitForFrame() to synchronize with the render thread if needed.

This runs in a tight loop in RunForever(), and is only run after the Render thread has started - i.e. after OnDeviceSetup() and OnRendererSetup() has been called, in that order.

Implementation may leave this empty if no action is needed.

Note

This should not be directly called.

Reimplemented from Foundation::Rendering::RenderApplication.

OnDeviceSetup()

void Examples::Win32_ScreenCaptureApp::OnDeviceSetup ( )

inlineoverrideprivatevirtual

Actions to take after device specific resources has been set up.

This is run on the main thread, i.e. the calling thread of Initialize(), after the device and swapchain is created, but before the Renderer is created.

Implementation may leave this empty if no action is needed.

Note

This should not be directly called.

Reimplemented from Foundation::Rendering::RenderApplication.

OnRendererSetup()

void Examples::Win32_ScreenCaptureApp::OnRendererSetup ( )

inlineoverrideprivatevirtual

Set up the renderer by creating passes, resources, and other configurations.

Note

This is where you should set up your rendering pipeline.

This is invoked by InitializeRenderer on the Render thread, within a Renderer::BeginSetup and Renderer::EndSetup clause, thus invoking Renderer::BeginSetup, Renderer::EndSetup here again is incorrect. and will be called again if the swapchain is recreated.

This MUST be implemented by the subclass.

This should not be directly called.

Implements Foundation::Rendering::RenderApplication.
