Jazz2::Rendering::UpscaleRenderPass class
#include <Jazz2/Rendering/UpscaleRenderPass.h>

Upscales input image usually to a native resolution.

Final output pass that renders the low-resolution scene through a rescale shader to the native output resolution, optionally routing it through an AntialiasingSubpass. Exposes the input scene node that the rest of the rendering attaches to.

Base classes

class nCine::SceneNode
Base node of the scene graph transformation hierarchy.

Derived classes

class UpscaleRenderPassWithClipping
Upscales input image usually to a native resolution, additionaly supports 3 independent layers (background layer, clipped main layer, overlay layer).

Constructors, destructors, conversion operators

UpscaleRenderPass()
Creates a new instance.

Public functions

void Initialize(std::int32_t width, std::int32_t height, std::int32_t targetWidth, std::int32_t targetHeight) virtual
Initializes the render pass.
void Register() virtual
Registers the render pass into the viewport chain.
auto OnDraw(RenderQueue& renderQueue) -> bool override
Called when the node needs to be drawn, returning true if a command was added.
auto GetNode() const -> SceneNode*
Returns the input scene node.
auto GetViewSize() const -> Vector2i
Returns size of the input image.
auto GetTargetSize() const -> Vector2f
Returns size of the upscaled target image.

Protected types

class AntialiasingSubpass
Optional antialiasing subpass.
