4dgspl.at — 4D Gaussian Splatting

4dgspl-tools

Open tools for making 4D Gaussian Splatting (4DGS) content with 4dgspl.at. Turn a 3D model, an animated character (for example from Mixamo) or a Blender scene into a synchronized multi-camera render with exact COLMAP calibration, validate it, and convert it to a 4DGS sequence that plays in the browser.

Built to be used by AI coding agents (Claude Code, Codex, …) as well as people. Agents: start with AGENTS.md.

Quick start

# 1. Camera ring + render + calibration (Blender 4.x)blender -b scene.blend -P tools/4dgspl_blender_rig.py -- --kamera 8 --yaricap 3.5 --cikti //teslim --render
# 2. Validatepython3 tools/4dgspl_kontrol.py teslim
# 3. Upload, process and download with your agent key (4dgspl.at → Projelerim → Ajan anahtarları)export DGSPL_ANAHTAR=4dg_…python3 tools/4dgspl_yukle.py teslim --gonder --bekle --indir result

Real footage without a calibration file: add --colmap (8+ cameras at most 45° apart, textured scene).

Rules that matter most:

• Background: pure black world (0, 0, 0).
• Materials: matte.
• Cameras: at least 6, 8 recommended; they never move.
• Timing: the key motion within the first 10 seconds.
• Framing: the subject fills 70–85 % of the frame height.

Agent skill

skills/4dgs-blender/SKILL.md packages the whole workflow as an agent skill: GLB 3D animation, video, still image and 4DGS videos from one Blender scene. To install it in Claude Code, copy the folder into ~/.claude/skills/. Agents that read SKILL.md from their own skills folder can use the same files.

MCP server

mkdir -p ~/.4dgspl && cd ~/.4dgspl && curl -O https://4dgspl.at/araclar/4dgspl_mcp.py \  -O https://4dgspl.at/araclar/4dgspl_yukle.py -O https://4dgspl.at/araclar/4dgspl_kontrol.pyclaude mcp add 4dgspl --env DGSPL_ANAHTAR=4dg_… -- python3 ~/.4dgspl/4dgspl_mcp.py   # Claude Codecodex mcp add 4dgspl --env DGSPL_ANAHTAR=4dg_… -- python3 ~/.4dgspl/4dgspl_mcp.py    # Codex

• Claude Desktop: install 4dgspl.mcpb from the latest release and enter the key in its settings.
• Other clients: command python3, argument the path to 4dgspl_mcp.py, environment DGSPL_ANAHTAR.
• Without a key, get_4dgs_guide and check_delivery still work.
• Listed in the MCP Registry as io.github.snmzzcenk/4dgspl (server.json). Build the bundle with python3 mcpb/build.py.

Output

4dgspl.at reconstructs every frame as a 3D Gaussian Splatting scene (gsplat). The output is:

• a compressed.ply sequence in PlayCanvas format;
• sahne.json with the frame count, fps, start camera and metrics;
• an MP4 preview.

Play the sequence in the browser with PlayCanvas, or open a single frame in SuperSplat.
