Enumeration Type Documentation

◆ DirectDrawingMode

Specifies where direct drawing operations are applied within the rendering pipeline.

This mode determines the coordinate space and lifecycle of direct drawing:

SceneLayer Draws in world space as part of a specific scene layer. Content scrolls, zooms, and parallax-moves with the camera.
View Draws in screen space at the view level. Content is fixed to the viewport and is not affected by camera movement, making it suitable for UI, overlays, and debug visuals.

Enumerator

SceneLayer

Performs direct drawing within a scene layer using world-space coordinates.

Drawing in this mode is affected by camera position, zoom, and layer parallax, and participates in the normal scene rendering and refresh logic.

View

Performs direct drawing at the view level using screen-space coordinates.

Drawing in this mode is independent of camera movement and world transforms, making it ideal for HUD elements, overlays, and diagnostic rendering.
