Spline User Builds Webcam-Controlled Dice Game With Omma AI.

A developer has extended their web-based rock-paper-scissors game with a new dice rolling feature that responds to hand gestures captured through a webcam. Joseph Azar announced the update on LinkedIn, highlighting that the entire experience runs in real time on the web and was built using Spline's Omma AI assistant.

The ShiFuMi 3D app now includes dice rolling alongside its existing hand gesture recognition for rock-paper-scissors gameplay. Users control the dice through hand movements detected by their computer's webcam, with no additional hardware or downloads required. Azar described the development process as "VibeCoded with AI in Omma," pointing to the platform's AI-assisted workflow for building interactive 3D experiences.

Spline launched Omma in March 2026 as an AI-powered platform that orchestrates multiple specialized agents to build 3D scenes, web apps, and interactive games from natural language descriptions. The system runs code generation, image creation, and 3D mesh production simultaneously, allowing developers to skip manual setup and move directly to customization.

The platform supports WebGPU for real-time physics simulations and reflections, which likely powers the dice rolling mechanics in Azar's game. Developers can integrate real data through CSV, JSON, and DOC files, as well as import GLB and GLTF 3D models. Omma projects deploy instantly to live URLs with custom domain support.

The toolset includes industry-standard web technologies like Three.js, Tailwind CSS, and React Three Fiber. Developers can generate multiple variations of an idea in parallel, select the best result, and continue iterating. As previously covered, Omma has demonstrated capabilities ranging from WebGL grids with GLSL shaders to custom fragment shaders for sub-pixel rendering.

Azar also noted that the background music in his demo video was generated within Omma, suggesting the platform's scope extends beyond visual and interactive elements to include audio generation. This integrated approach to content creation aligns with Omma's multi-agent architecture, where different AI systems handle specialized tasks within a single workflow.

The dice game demonstrates how browser-based 3D tools are enabling real-time computer vision applications without requiring users to install native software. By leveraging WebGPU and webcam APIs, developers can build gesture-controlled experiences that run entirely in the browser. The approach removes friction for end users while giving creators access to sophisticated real-time rendering and input detection.

Spline's community gallery allows developers to fork and remix existing projects, potentially accelerating adoption of webcam-based interactions in web applications. The platform remains in beta, with the company describing the current state as experimental while the core engine is production-ready.
