anchors). Build and deploy the same project for multiple platforms.
Integrate with various IDEs (Lazarus, Delphi, Visual Studio Code...).
Terrain with water and trees

Components

A lot of components to design viewport contents (3D and 2D world,
using scenes, cameras, navigation, primitives, lights...) and user
interface (buttons, images, labels...).
Village scene with outlines in glTF from Sketchfab ( https://
sketchfab.com/3d-models/ftm-0970f30574d047b1976ba0aa6f2ef855 by Luis
Fernandez )

Lots of ways to define data

Use 3D models, 2D animations, sprite sheets. Great integration with
authoring tools like Blender or shops like Sketchfab thanks to using
open standards like glTF and X3D.
Real-time water with caustics, reflections, shadows

Graphic effects

Composable shader effects, shadows, mirrors, physically based
rendering, bump mapping, gamma correction...
"Escape from the Universe" on Nintendo Switch
