Introduction

Creating 3D models using real-world objects has become increasingly accessible, thanks to advancements in technology. In this guide, we'll explore how to convert photos into a detailed 3D model using your mobile phone, photogrammetry techniques, and Adobe Substance 3D Sampler.

Step 1: Capturing Photographs

To begin, you’ll want to capture a series of images of a real-world object. For this demonstration, I used a piece of brick located in my underground parking. It's essential to take at least 20-30 photos from various angles to gather enough data for a good 3D reconstruction. Even if some images lack quality, you'll be surprised at how they can come together to form a realistic model.

Step 2: Using Adobe Substance 3D Sampler

  1. Launch Adobe Substance 3D Sampler: Start by opening the app. It may take a few moments based on your computer’s speed.
  2. Create a New Project: Click on "Create new" and then select "Add a 3D capture."
  3. Import Photos: Drag the captured images directly into the application. For this example, I imported around 25 images.
  4. Processing: Once the images are loaded, submit them for processing. This process involves your computer using both the GPU and CPU to analyze the images and create a 3D mesh model.

Step 3: Refining the 3D Model

  1. Cropping the Model: After the process is complete, you'll see all the photographic data represented as a model. Crop the area of interest to exclude any unnecessary elements.
  2. Generate the 3D Mesh: After you've selected the desired area, create the mesh. Name your file (e.g., "break_01") and finalize it.
  3. Exporting the 3D Model: You can export your model in various formats, with FBX being a popular choice due to its compatibility with many software applications like Blender, Unity, and more.

Step 4: Importing into Blender

  1. Open Blender: Start a new project in Blender 4.1.
  2. Import FBX: Delete the default cube, then go to File > Import > FBX. Select the model you just exported.
  3. Adjust the Scale: Use the scale tool to adjust the size of your model appropriately.
  4. Apply Modifiers: To make your model game-ready, use the Decimate modifier to reduce the polygon count without losing detail.
  5. Save Your Project: Finally, save your Blender file and create another copy with reduced polygons for game development.

Conclusion

This tutorial demonstrated how to convert photographs into a 3D model using photogrammetry technology with Adobe Substance 3D Sampler and Blender. With the tools available today, anyone can start creating realistic 3D models, so get out there with your mobile phone and start capturing your world!

FAQ

1. What is photogrammetry?
Photogrammetry is the process of using photography to measure and create 3D models or representations of real-world objects.

2. Do I need a high-quality camera to create 3D models using photogrammetry?
No, you can use a mobile phone to take pictures. The key is to take sufficient images from multiple angles.

3. Are there other software options besides Adobe Substance 3D Sampler?
Yes, there are other photogrammetry software options like Agisoft Metashape and RealityCapture, but Adobe Substance 3D Sampler is user-friendly for beginners.

4. Can I use the 3D models in game development?
Absolutely! The exported FBX models can be used in various game development software like Unity or Unreal Engine.

5. What should I keep in mind while capturing photos for photogrammetry?
Ensure you have good lighting, overlap between photos, and capture from various angles to provide enough data for a detailed 3D model.
