SAM 3D Body C++ MoCapby AmmarkoV
Performs real-time 3D full-body reconstruction and 70-joint skeleton tracking from a single camera using ONNX and ggml in pure C++. It's also a popular Free Alternative to Rokoko Studio / Plask AI for creators who don't want to pay a monthly subscription.
What Is SAM 3D Body C++ MoCap?
New to GitHub repos? Here's what this actually does, in plain language:
Bhai, agar aapko Blender ya Unreal Engine ke liye bina expensive motion capture suits ke 3D character animation chahiye, toh yeh tool single webcam se BVH output de deta hai.
Strengths, Limitations & Is It Safe to Install?
An honest breakdown before you install anything on your PC:
โ What It Does Well
- Runs lightning fast without heavy Python dependency overhead thanks to pure C++ and ggml
- Exports standard BVH files that drop straight into Blender's armature system smoothly
- Captures multi-person tracking from a single normal webcam feed without special hardware
โ What It Can't Do / Limitations
- Requires compiling C++ source code manually, which will block absolute beginners used to .exe installers
- Fails to track accurately during heavy occlusion or when subjects turn completely sideways
- Documentation assumes prior experience building C/C++ repositories with CMake and CUDA
๐ก๏ธ Is It Safe to Install?
The software itself is safe open-source code, but recording full-body motion capture of individuals without their explicit consent raises privacy and data protection concerns.

How to Use SAM 3D Body C++ MoCap (Beginner Quick Start Tutorial)
First time launching this application? Follow our beginner operational workflow:
Clone Repository
Clone the repository and submodules using git.
git clone --recursive https://github.com/AmmarkoV/SAM3DBody-cpp.gitDownload Weights
Download the required ONNX and ggml model weights specified in the repo README and place them in the weights folder.
Build with CMake
Configure and build the C++ project using CMake on your local machine.
mkdir build && cd build && cmake .. && make -j4Run Inference
Execute the compiled binary pointing to your input video file to generate the BVH motion data.
./sam3d_body --input input_video.mp4 --output motion.bvhTroubleshooting & Fix Common Errors
If you encounter unexpected errors or installation failures, apply these verified diagnostic fixes:
Root Cause: Your GPU VRAM is full because the AI model batch size or resolution is too high.
Root Cause: The required software is installed but not added to your Windows Environment System PATH.
Root Cause: Installed PyTorch binary does not match your Nvidia GPU CUDA driver version.
Root Cause: Another WebUI or Python background process is already running on the default local port.
