Photo to 3d Model (Quick Tutorial)

Introduction

Creating a 3D model from a single photo can be an exciting and creative project. This guide will walk you through the steps to transform a photo into a 3D model using an open-source program called PiFu HD. By following these straightforward instructions, you'll be able to create a detailed and textured 3D representation of yourself or any subject.

Steps to Convert a Photo into a 3D Model

Step 1: Capture Your Photo

1. Take a Video: Record a video of yourself in the pose you wish to render as a 3D model. Make sure to position yourself in the middle of the frame for the best results.
2. Export a Frame: Select a single frame from the video, ensuring it is saved as a PNG file. Confirm that the file is in RGB with alpha for optimal results.

Step 2: Use PiFu HD

1. Access PiFu HD: Open PiFu HD, an open-source program designed to convert PNG photos into 3D models using AI technology.
2. Stage Setup:
   • Click on the "Collab" button at the bottom of the page.
   • A new page will load; copy the project to your drive.
   • Connect to the host runtime by clicking the relevant button on the right side of the screen.

Step 3: Import Your Photo

1. Configure Input Data:
   • Scroll down and hit the "Go" button for both the clone and configure input data sections.
   • Open the folder that appears, where you'll find the PiFu HD folder.
2. Add Your PNG:
   • Import your PNG file into the sample images directory.
   • Right-click to rename your file and use Ctrl+C to copy the name.
   • Locate the line of code with "test.png" and replace "test" with the name of your PNG file.

Step 4: Run the Model

1. Execute the Code: Scroll back up and click on "Run Time," then select "Run After" to start the calculation process.
2. Access Results: Once the calculation completes, close the folder and reopen it to find the results folder containing your new 3D model.
3. Download the Model: Download the generated 3D model to your device.

Step 5: Final Touches

1. Importing the Model: Open the 3D model using your preferred software; use soft selection for any necessary retouches.
2. Create Material and Texture:
   • Import the PNG texture file you created earlier.
   • Apply this material to your model.
   • Generate UV coordinates and adjust your model to best match these coordinates.

Step 6: Utilize Your Model

Now that you have a textured 3D model, you're free to perform simulations or rig the model for animation, allowing you to create dynamic and fun movements.
