The API integrates with the normal Codename +One UI: a 3D scene lives inside a regular component that you add to a `Form` like +any other. + +[IMPORTANT] +==== +*Your `Renderer` callbacks run on the native platform render thread -- NOT the +Codename One EDT.* This is the single most important thing to understand before +you write any 3D code. + +`onInit`, `onResize`, `onFrame` and `onDispose` are invoked on the underlying +OS/GPU render loop (GL / Metal / Direct3D), not on the event dispatch thread. +From inside them you must *not* touch Codename One UI components, show forms, or +call other EDT-only APIs. To push data back to the UI (for example to update a +HUD label or react to a game event) hop onto the EDT with `CN.callSerially(...)`. +Conversely, treat the `GraphicsDevice` and the objects it hands you as owned by +the render thread. +==== + +WARNING: 3D is a low-level, GPU dependent feature. Always guard usage with +`CN.isGpuSupported()` (or `RenderView.isSupported()`); on a platform without a +backend the `RenderView` reports unsupported so you can fall back to 2D. + +=== Concepts + +The API is intentionally "hybrid": a low level command layer (buffers, textures, +render state, draw calls) for full control, plus high level helpers (meshes, +materials, a camera) for common cases. Crucially, *you never write shader source*. +Instead you describe a https://www.codenameone.com/javadoc/com/codename1/gpu/Material.html[Material] +(a lighting model plus color and texture) and the engine generates the matching +platform shader behind the scenes: GLSL ES on OpenGL ES and WebGL, GLSL on the +desktop simulator, Metal Shading Language on iOS and Mac, and HLSL on the native +Windows (Direct3D) port.
