Photo to 3d Model (Quick Tutorial)
People & Blogs
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
- 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.
- 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
- Access PiFu HD: Open PiFu HD, an open-source program designed to convert PNG photos into 3D models using AI technology.
- 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
- 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.
- 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
- Execute the Code: Scroll back up and click on "Run Time," then select "Run After" to start the calculation process.
- Access Results: Once the calculation completes, close the folder and reopen it to find the results folder containing your new 3D model.
- Download the Model: Download the generated 3D model to your device.
Step 5: Final Touches
- Importing the Model: Open the 3D model using your preferred software; use soft selection for any necessary retouches.
- 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.
