Hology Engine

Hology Engine is a game engine designed for creating 3D games and interactive experiences that run on web, mobile, and VR platforms. It leverages web technologies, including TypeScript and Three.js, to enable developers to build immersive environments directly for the web and related platforms. The engine is aimed at those seeking to develop visually rich, interactive 3D worlds with tools that emphasize both performance and creative flexibility.

Among its core features, Hology Engine provides landscape sculpting capabilities, allowing users to shape expansive terrains within its editor and assign materials to different areas through painting. The engine manages performance by automatically loading or removing sections of the landscape based on the camera's view distance. It includes a built-in physics engine supporting accurate collision detection, ray casting, and physics simulations, which is essential for creating realistic interactions within game environments.

For character animation and movement, Hology Engine offers a kinematic character movement component and an animation system capable of blending different animations for the upper and lower body, adapting seamlessly to changes in movement state. Developers can also create custom graphical effects using a node-based shader system that enables writing GPU shaders in TypeScript; these shaders are integrated into the editor for parameterization and reuse. Additionally, the engine supports procedural foliage generation, allowing for the automatic placement of grass and other vegetation across landscapes in a way that adapts to the environment.

Hology Engine is accessible via download and offers a sign-up process, with an option to sign up for free. The tool is positioned for developers who want to build 3D games and experiences using modern web technologies across multiple platforms. Documentation, feature highlights, and additional resources are available through its website.
