3.1. KONGFU VR Development Engine

Using the cross platform 2D and 3D game engine unity,, KONGFU VR can develop cross platform video games and extend to the HTML5 web platform based on WebGL, technology,as well as the new generation of multimedia platforms such as tvOS, OculusRift and ARKit. In addition to being used for the development of video games, Unity is also widely used as a comprehensive creation tool for interactive content such as architectural visualization and real-time 3D animation, which is optimized for the development of XR (including VR, MR and AR).

Unity involves deep platform integration, unity engine improvement and XR technology stack optimization for each platform.

Unity supports the following platforms for XR:

• ARKit

• ARCore

• Microsoft HoloLens

• Windows Mixed Reality

• Magic Leap

• Oculus

• OpenXR

• PlayStationVR

XR Interaction Toolkit Insert UNITY

XR interaction toolkit is a component-based advanced interaction system for creating VR and AR experiences. It provides a framework to make 3D and UI interaction available from Unity input events. The core of the system is a set of basic interactors and interactive components, as well as the interaction manager that connects the two types of components.

Meanwhile, KONGFU VR uses Unreal Engine5 game engine developed by Epic Games. The game engine is mainly designed for, first-person games and supports the latest systems, including the sub, era game console Playstation 5 and Xbox series X / s.

Unreal engine5 adopts two core technologies, which will become another underlying technology necessary for "cinematization".

• Nanite, an advanced technology that allows the introduction of high-detail photography source materials into the game, can be used to deal with complex geometry in the game scene;

• Lumen,used to solve the lighting details of the game.

At the same time, epic will fully open the Quixel Megascans material library to developers, so as to make it possible for small teams to make high-level (image quality) content using the Unreal Engine.
