Class Documentation

class Viewport

Editor viewport that renders the scene to a separate render target displayed in ImGui.

The Viewport class renders the scene to its own RenderTarget instead of directly to the swapchain. This rendered image is then displayed as an ImGui::Image within a “Viewport” window.

Public Functions

Viewport(const renderer::vulkan::VulkanSwapchain &swapchain, RuntimeModule &runtime_module)

Constructs a Viewport with initial dimensions from the swapchain.

Parameters:

• swapchain – Used to determine initial viewport size and color format.

• runtime_module – The runtime module that handles scene rendering.

void on_gui_update(const FrameContext &frame)

void render(FrameContext &frame) const

Renders the scene to the viewport’s render target.

Parameters:

frame – The current frame context.
