Package eu.svjatoslav.sixth.e3d.headless

package eu.svjatoslav.sixth.e3d.headless

Headless rendering toolkit: windowless snapshots, pixel assertions, golden-image comparison and scene-state dumps.

Everything here works without a display, a Swing frame or a render thread, driving the same transform/sort/paint pipeline the on-screen path uses. Built for automated verification (tests, doc tooling, AI agents), but equally useful for batch thumbnail generation.

• Snapshot — render a scene to a BufferedImage; pose strings
• PixelAssertions — "did this region get painted?"
• GoldenImage — compare against a reference PNG
• SceneDump — shapes/lights/camera/GI state as text
