Toyota announces Fluorite game engine — built on Dart/c++ api, Flutter toolkit using Filament 3D rendering engine on top of Yocto project's AGL Linux​

Toyota Connected North America is Toyota Motor Corporation's subsidiary founded in collaboration with Microsoft for working on in-vehicle software, AI, and related tech initiatives. Toyota Connected developers announced at FOSDEM 2026 their Fluorite game engine as a "console grade" engine built around Flutter and Dart. Fluorite also makes use of Google's Filament 3D rendering engine.

With Fluorite they are leveraging Filament, SDL, and other well known options and relying on the Dart programming language code for both UI and game logic handling. They also have plans to integrate Jolt Physics.


Options like Unity and Unreal Engine were rejected due to proprietary blobs, resource weight, and licensing fees. Meanwhile for Godot they found long start-up times and being too resource heavy. Other options were found to be unstable or lacking a stable API.

Tesla Ditches Godot for Unreal Engine in Graphics Overhaul​

Tesla switching to Epic's Unreal Engine for FSD visualizations in major upgrade

by The Tech Buzz
PUBLISHED: Wed, Aug 13, 2025, 10:36 PM UTC | UPDATED: Sat, Feb 7, 2026, 4:01 AM UTC

TL;DR:
• Tesla hacker discovers Unreal Engine code in 2025.20 firmware for Model S/X with AMD chips
• Switch from current Godot engine would upgrade FSD visualization quality significantly
• Tesla joins Rivian, Ford, GMC, Volvo, and Lotus using Epic's automotive platform
• Move signals Tesla's push for premium in-car experience as FSD competition intensifies


Tesla is quietly overhauling its Autopilot and Full Self-Driving visualizations with a switch to Epic Games' Unreal Engine, according to firmware evidence discovered in the company's latest 2025.20 update.

Currently, Tesla relies on the open-source Godot engine to render the real-time visualizations that show detected vehicles, pedestrians, traffic cones, and road markings on the car's central display during Autopilot and Full Self-Driving operation. While functional, these graphics have long been criticized as basic compared to the sophisticated interfaces promised by competitors like Mercedes-Benz and BMW.

Top 5 Embedded HMI UI Frameworks for 2025​

12 June 2025

Przemyslaw Krzywania
HMI Director
Embedded human-machine interfaces, or HMIs, require UI frameworks capable of delivering smooth, visually rich, and highly responsive graphics across diverse hardware platforms, from low-power microcontrollers used in everyday appliances to advanced SoCs powering automotive digital cockpits.

Flutter: Designed for polished UIs and rapid iteration. Great if you want app-like fluidity on embedded Linux or plan to reuse code across mobile, desktop, and embedded. Perfect for consumer devices and infotainment systems, provided hardware resources are sufficient.

Unreal Slate UI: For high-end, graphics-intensive projects. If you need cinematic visuals, 3D realism, or a “wow factor” (luxury cars, simulators, premium interfaces), Unreal stands apart. Overkill for simpler HMIs, but unmatched in the right context.

Google open sources Filament - a physically based rendering engine for Android, Windows, Linux and macOS​

2018-08-06 08:30:47

Google has just open-sourced Filament, their physically based rendering (PBR) engine for Android. It can also be used in Windows, Linux, and macOS. Filament provides a set of tools and APIs for Android developers to help them easily create high-quality 2D and 3D rendering.

Filament is currently being used in the Sceneform library both at runtime on Android devices and as the renderer inside the Android Studio plugin.

Google’s Filament comes packed with the following features:

• The rendering system is able to perform efficiently on mobile platforms. The primary target is OpenGL ES 3.x class GPUs.
• The rendering system emphasizes overall picture quality.
• Artists are able to iterate often and quickly on their assets and the rendering system allows them to do so instinctively.
• The physically based approach of the system also allows developers to create visually believable materials even if they don’t understand the theory behind the implementation.
• The system relies on as few parameters as possible to reduce trial and error and allows users to quickly master the material model.
• The system uses physical units everywhere possible: distances in meters or centimeters, color temperatures in Kelvin, light units in lumens or candelas, etc.
• The rendering library is as small as possible so any application can bundle it without increasing the binary to unwanted sizes.

Filament APIs​

There are two major APIs used.

• Native C++ API for Android, Linux, macOS, and Windows
• Java/JNI API for Android, Linux, macOS, and Windows

https://www.packtpub.com/en-us/lear...sources-filament-rendering-engine-for-android

Filament runs both on OpenGL and Vulkan. and there is a Java API.
It is written in C++ with Vulkan and has both a c++ and a Java API for access.

Flutter is an open-source UI software development kit created by Google. It can be used to develop cross platform applications from a single codebase for the web,[4] Fuchsia, Android, iOS, Linux, macOS, and Windows.[5] First described in 2015,[6][7] Flutter was released in May 2017. Flutter is used internally by Google in apps such as Google Pay[8][9] and Google Earth[10][11] as well as by other software developers including ByteDance[12][13] and Alibaba.[14][15]
Flutter ships applications with its own rendering engine which directly outputs pixel data to the screen.[16][17] This is in contrast to many other UI frameworks that rely on the target platform to provide a rendering engine, such as native Android apps which rely on the device-level Android SDK or IOS SDK which use the target platform's built-in UI stack. Flutter's control of its rendering pipeline simplifies multi-platform support as identical UI code can be used for all target platforms.[17]

https://en.wikipedia.org/wiki/Flutter_(software)

Flutter​

Google introduced Flutter for native app development. Built using Dart, C, C++ and Skia, Flutter is an open-source, multi-platform app UI framework. Prior to Flutter 2.0, developers could only target Android, iOS and the web. Flutter 2.0 released support for macOS, Linux, and Windows as a beta feature.[67] Flutter 2.10 released with production support for Windows[68] and Flutter 3 released production support for all desktop platforms.[69] It provides a framework, widgets, and tools. This framework gives developers a way to build and deploy mobile, desktop, and web apps.[70] Flutter works with Firebase[71] and supports extending the framework through add-ons called packages. These can be found on their package repository, pub.dev.[72] JetBrains also supports a Flutter plugin.[73]

https://en.wikipedia.org/wiki/Dart_(programming_language)

While initially targeted at automotive displays, the platform could eventually extend to consoles such as Xbox or PlayStation.

Positioned as the first console-grade engine fully integrated with Flutter, Fluorite delivers hardware-accelerated graphics via Vulkan, alongside physically based rendering, accurate lighting, post-processing effects, custom shaders, and multiple simultaneous 3D scene views.

“Its reduced complexity [is achieved] by allowing [developers] to write your game code directly in Dart and using all of its great developer tools. By using a FluoriteView widget, you can add multiple simultaneous views of your 3D scene, as well as share state between game entities and UI widgets – all in the Flutter way,” said the Fluorite development team.

Toyota built the engine to avoid the resource weight, complexity, and licensing costs of Unity and Unreal, and the start-up overhead of Godot, aiming instead for a lighter, extensible, licensing-friendly platform tailored for embedded automotive environments.

Toyota drives development of open source game engine​

Texas-based developers from Toyota Connected announced this news at FOSDEM 2026 in Brussels, Belgium. The event is a free, community-driven conference for developers, researchers and users of open source software.


The team are said to have developed Flourite because the Unity and Unreal engine carried too much resource weight and also came with more onerous licensing fees. Another well-known game engine, Godot, was also rejected due to its resource-intensive neediness and its over-long start-up times.

Four key features are currently being showcased on Flourite’s official webpage:

The first is a high-performance Entity Component System (ECS) core, which is written in C++ to squeeze out as much performance and create room for optimization for weaker hardware. At the same time, it allows devs to use Dart and higher-level game tools, so they can transfer knowledge from other game engines.

The second is model-defined trigger touch zones, which allow digital artists to set up “clickable” areas right inside Blender and assign them to trigger certain actions. Then, developers can hook up the click events to whatever behavior they want, which makes building 3D interfaces a lot simpler, and lets end-users interact with objects and controls in a more intuitive way.

The third is console-grade 3D rendering, which is powered by Google’s Filament renderer and uses modern, console-grade graphics APIs to make games look prettier.

Last is support for Flutter’s Hot Reload feature, which allows developers to update their scenes and quickly see changes in just a few frames. This allows teams to confirm their edits and iteratioons faster, speeding up the game development process.
