Class HeadlessRenderDevice

java.lang.Object

dev.engine.graphics.common.HeadlessRenderDevice

All Implemented Interfaces:

RenderDevice, AutoCloseable

public class HeadlessRenderDevice
extends Object
implements RenderDevice

A render device that does nothing — for testing without a GPU. All resource operations return valid handles. Submit is a no-op.
