Have you ever wanted to quickly shape a 3D environment and immediately walk through it, without waiting through massive software installation times or setting up a complex game engine?
Enter TELU 3D Studio—a lightweight, native C++ application that bridges the gap between 3D modeling and playable web games. Designed for speed, portability, and zero friction, TELU lets you model, texture, and transform your 3D scenes into playable HTML5 web games with a single keystroke.
Whether you are an indie developer, a 3D environment artist, or a game dev hobbyist, TELU 3D Studio gives you a streamlined pipeline to bring your spatial ideas to life.
What is TELU 3D Studio?
TELU 3D Studio is a free, native 3D modeling application and web game builder developed in C++17 and OpenGL. Unlike modern desktop apps bloated with Electron or browser wrappers, TELU launches instantly, runs smoothly on modest hardware, and keeps your creation workflow completely focused.
The core philosophy behind TELU is simple: Model it. Texture it. Play it.
Key Features Built for Creators
1. Intuitive Mesh Editing & UV Mapping
Shape your world starting from basic primitives or import existing 3D models (FBX and OBJ). TELU offers a full-featured Edit Mode with vertex, edge, and face selection, complete with essential operations:
- Extrude, merge, split edges, and flip normals.
- Smooth and flat shading toggles with snapping and gizmo controls.
- Built-in UV Editor to manually arrange, scale, and align textures for seamless low-poly and stylized art styles.
2. Instant Web Game Engine (Press F5)
The standout feature of TELU 3D Studio is its one-click Build & Run system. Simply place a Spawn Point inside your scene and press F5.
TELU instantly compiles your 3D level into a static three.js web game, fires up a local web server, and opens your browser. You can immediately walk around your environment using standard FPS controls (WASD, mouse look, jump).
3. Cross-Device & Mobile Testing over Wi-Fi
Want to test how your 3D world feels on mobile? TELU hosts your game on your local network. Simply open the generated link on your smartphone over Wi-Fi to test full touch controls, complete with an on-screen joystick and jump button.
4. Clean & Open Pipeline
TELU respects your workflow and ownership:
- No Proprietary Lock-in: Projects are saved in clean, readable JSON (
.telu). - Export Anywhere: Export your creations to industry-standard glTF 2.0 (GLB) or OBJ + MTL for direct use in Unreal Engine, Unity, Godot, or Blender.
- Ready for Web Hosting: The build output generates a standalone HTML5 static website folder ready to upload directly to platforms like itch.io or GitHub Pages.
How it Works: From Blank Canvas to Playable Game in 3 Steps
- Model: Add basic primitives or import assets. Modify geometry using intuitve Edit Mode tools and drop a player Spawn Point into the scene.
- Texture: Drag and drop PNG or JPG textures onto your objects. Apply box, planar, cylindrical, or spherical UV projections and fine-tune layout using the UV Editor.
- Play & Export: Press F5 to test your game locally, or export the pre-configured static web folder to host your game online anywhere.
Why Choose TELU 3D Studio over Heavy 3D Tools?
- Lightning Fast Performance: Native C++ implementation means zero lag, instant opening, and low RAM consumption.
- 100% Free & Open Tech: Built on permissive open-source frameworks (SDL3, Dear ImGui, OpenGL, three.js). No subscriptions, no account creation, no watermarks.
- Zero Engine Setup: Go straight from blockout to playing in browser without configuring lighting pipelines, physics engines, or complex export scripts.
