Real-time 3D scene workflow
SceneKit-based viewer architecture keeps sketching interactive while the camera moves through depth.
Technical overview
METASPACE TECHNICAL IMPLEMENTATION
Metaspace is a spatial sketch engine for iPhone and iPad. It combines real-time 3D rendering, precision drawing input, project intelligence, and portable packaging in one cohesive workflow.
Proof points
Implementation-backed capabilities
Precision input pipeline
PencilKit capture and touch gestures are paired with a drawing layer sandwiched between two viewer layers, so depth stays visually explicit as you sketch.
Structured project model
Layers, viewpoints, and metadata persist per space so complex sketches remain organized and editable.
Portable .mtspz packages
Export and import carry scene, metadata, and preview together for shareable and archive-ready project transfer.
Fast preview and discovery
Generated preview images and Quick Look thumbnail support make large libraries easier to scan and reopen.
Productized content systems
Manifest-driven demos, learning modules, and unlock flows connect the core engine to long-term usage.
Architecture
Layered spatial system design
Metaspace is designed as a layered stack: interaction and rendering at the front, persistent project intelligence in the middle, and distribution systems for packaging and previews at the edge. In the editor view, the active drawing layer sits between front and back viewer layers so users can see exactly which depth plane they are drawing on.
Six-layer architecture narrative
Product experience is built on top of a stable rendering and persistence core, with clear distribution and growth systems.
Core runtime flow
Input is routed into the live scene, persisted as independent scene and metadata artifacts, then packaged and previewed for sharing.
Workflow
Sketch, organize, share, reopen
Portable spatial continuity
Metaspace preserves creative state between sessions and devices by treating each space as structured project data, not just image output.
Responsive save architecture
Debounced persistence and task-queued operations protect editing flow while keeping project state current and durable.
