Class RenderTargetManager

java.lang.Object

dev.engine.graphics.common.RenderTargetManager

public class RenderTargetManager
extends Object

Manages render target lifecycle: creation, resize, and pooling.

Supports color-only, color+depth, and multiple render target (MRT) configurations. Named render targets can be resized as a group (e.g., on window resize). Transient render targets are pooled for reuse by the render graph.
