Description
Plan a shot before generating it. Reelpen is a browser-based 3D scene builder: arrange characters and environments, direct movement and cameras, then export reference videos or PNG keyframes. Connect a compatible AI assistant through authenticated MCP to inspect and edit permitted scenes. Free beta; external AI services are separate.

Could you build this?
Partial While Three.js/Babylon.js scene builders and MCP endpoints can be generated with AI assistance, building a performant browser-based 3D editor with real-time camera direction, multi-track animation timelines, and deterministic video/PNG frame rendering requires non-trivial 3D graphics engineering.
What it would actually take: Requires Three.js or WebGPU with custom transform controls, scene-graph state management, and an animation sequencer (like theater.js). The MCP server wraps JSON-RPC methods into scene mutation events. The hardest engineering involves handling complex rigged 3D assets, bounding-box physics, and headless off-screen canvas rendering to export consistent reference video keyframes.
