# GLTF Models

### Native GLTF architecture for seamless 3D scene processing and industry-standard model transmission.

**Adopting GLTF as the primary architectural standard guarantees efficient transmission of complex 3D models and immersive scenes.** By utilizing this open standard, the SCORE engine ensures seamless compatibility with industry-standard 3D software while maintaining a high-performance rendering pipeline. This standardized runtime allows the engine to instantly load complex asset hierarchies, skeletal rigs, and PBR materials. Furthermore, the engine's architecture allows STD.DEV to hook directly into standard GLTF nodes and attach custom procedural or volumetric shaders, dynamically extending static assets with advanced visual effects.

### Spatial Interaction & Kinetic Deformation

To create a truly responsive spatial experience, loaded GLTF models can be voxelized into dynamic particle structures directly within WebXR environments. Instead of rendering static meshes, the engine translates GLTF geometry coordinates into volumetric point grids, applying physical particle simulations in real time. Because the UI elements and every scene object share the same input devices, this kinetic structure integrates with a unified spatial selection system. Up to 1024 individual controllers can be tracked concurrently, writing their position and direction states into a GPU data texture. Vertex shaders sample this texture to compute real-world forces—such as hand-tracking pinch gesture vectors or controller rays—to disperse or warp the voxelized particles, transforming static 3D models into highly tactile interactive objects.

### Generative AI Parameter Orchestration

To guide these custom shaders and particle simulations, the SCORE framework utilizes Genkit AI to orchestrate the rendering parameters and transformation matrices. SCORE AI can utilize concrete triggers like microphone volume or device acceleration to automatically modulate the coefficients of the custom shader attachments or the variables of the voxel simulation. For instance, based on these inputs, Genkit can scale particle counts, adjust voxel grid resolution, or blend the transition between skeletal animations and physical simulations. This allows the AI layer to dynamically control complex rendering and physics systems, translating user environment changes into high-end interactive digital experiences.
