Introduction
Do you have old family photos gathering dust? Why not breathe new life into them by converting them into 3D models? It’s easier than you might think, and you don’t need any specialized software or equipment to get started. In this guide, we’ll walk you through the process of turning your photographs into 3D models using popular design tools such as SelfCAD, Autodesk 123D, and Agisoft Photoscan. We’ll provide detailed instructions for each software to help you preserve your cherished memories in a dynamic, three-dimensional format.
How to Convert an Image into a 3D Model Using SelfCAD
SelfCAD is a user-friendly tool for creating 3D models from photos or from scratch, making it accessible even for those without prior 3D design experience. The software integrates artistic, technical, rendering, and 3D printing tools, allowing you to complete your projects within a single platform. After designing your 3D models, you can use SelfCAD’s online slicer for 3D printing, eliminating the need to switch between different programs. The video below demonstrates how to slice STL files in SelfCAD.
SelfCAD operates through all major web browsers and also offers downloadable versions for Windows and Mac, so you can design anytime, anywhere. To convert an image into a 3D model using SelfCAD, follow these steps:
Step 1: Capture Your Object
Choose a manageable-sized object to ensure it fits within the frame and is easy to maneuver. The success of your 3D model depends on the quality and quantity of your photos. Higher quality images will yield more accurate models. Place the object in the center of the frame and take a series of 30-40 photos from different angles, including top views. Enhancing your images with newspaper or sticky notes around the object can improve results. Ensure you use good lighting and avoid underexposed or overexposed photos. Steer clear of flat, reflective, or transparent surfaces, as these are challenging to model effectively.
Step 2: Import Your Image to SelfCAD
Upload your captured images into SelfCAD by selecting the Image to 3D tool from the toolbar. Once uploaded, you can start transforming your image into a 3D model.
Step 3: Convert the Image to a 3D Model
Adjust the settings for Resolution, Tolerance, Amount, and Blur to convert your image into a 3D model. Set Resolution and Amount to their maximum values, and adjust Tolerance to slightly beyond the middle range. Select the Flip Background and Simplify options to complete the transformation.
If you plan to 3D print your model, select the 3D Print option from the toolbar, which will direct you to the slicer tool. Here, you can generate the G-code for your 3D printer. With this guide, you can now move on to exploring how to achieve similar results using Autodesk 123D.
How to Color Meshes on a 3D Model in SelfCAD
In 3D modeling, mesh coloring involves various techniques and tools, each serving unique purposes. This guide provides an overview of effective methods for coloring meshes in SelfCAD, along with practical steps to achieve well-defined and visually appealing results.
Step 1: Import and Configure the 3D Image: Start by navigating to the Image to 3D category and importing your reference image. Set the resolution to 250 and enable the “Flip Background” option to enhance image density and set extrusion parameters.
Step 2: Check Image Resolution: Select the “Mesh + Wireframe” view to examine the image’s resolution. You’ll notice approximately 96,000 divisions, indicating pixelation. Switch back to the solid view for the next steps.
Step 3: Simplify the Model: To reduce pixelation, go to the Modify category and use the “Simplify Object” tool. Set the intensity to 5 to decrease the divisions from 96,000 to 19,000. Review the model in “Mesh + Wireframe” to see the uniform resolution. This simplification helps in defining the basic shape for coloring.
Step 4: Adjust Image Tolerance: Use the Polygon Selection tool and adjust the tolerance setting to 2. This helps in defining larger faces more clearly, though it may complicate selection of intricate faces. Clean up any discrepancies to ensure accuracy.
Step 5: Color the Back Face: Select and copy the back face of the model. Use the color picker to apply a peach color. You might notice a flickering effect due to overlapping colors on different faces.
Step 6: Add Thickness and Scale: To address the flickering issue, go to the Modify category and use the “Add Thickness” tool. Set the thickness to 20 and then scale the colored object along the y-axis to intersect with the middle of the original model’s thickness. Adjust the scale sideways to cover the cutout sections.
Step 7: Merge and Color Profiles: Select both profiles and use the “Stitch and Scoop” tool to create intersections. Color different faces as needed, using inverse selection for complex or previously deselected areas.
Step 8: Choose Materials: In the material selection menu, you can choose from seven different materials. You can also merge materials by selecting and combining different colors.
Creating a 3D Model with Autodesk 123D Design
Autodesk 123D Design is a versatile 3D modeling software perfect for creating and visualizing various models, from products to structures and spaces. This tool is especially beneficial for beginners eager to learn how to create a photo to 3D model transformation. Here’s a step-by-step guide to creating a 3D model using Autodesk 123D Design:
Step 1: Import Photos into Autodesk 123D: Install Autodesk 123D Catch and import your photos into the software. The program can generate a 3D model from a set of images. Save your project to Autodesk’s cloud storage or other preferred cloud services. You can view your model online and share it by clicking the “Share” button located in the lower right corner.
Step 2: Refine Your 3D Model: Use Autodesk 123D Catch to clean up any imperfections in your 3D model. Remove unwanted features with the “Lasso” tool and fill gaps with the “Heal” tool to improve the model’s quality.
Step 3: Edit Your 3D Model: For further modifications, consider using SelfCAD to enhance or add new elements to your 3D model. You can blend, texture, sculpt, or paint your model as needed. SelfCAD offers a vast gallery of over 10,000 models and a resource for free 3D models to inspire your design.
Creating a 3D Model with Agisoft Photoscan
Agisoft Photoscan is another powerful tool for generating high-quality image to 3D model conversions. It’s user-friendly and ideal for creating detailed 3D images. Here’s how to use Agisoft Photoscan for 3D modeling:
Step 1: Choose Your Subject: Select a subject that is manageable in size. Large objects or structures can complicate the process, potentially exceeding the frame size. Choose something smaller to simplify your work. Consider taking multiple reference photos for a comprehensive view.
Step 2: Capture Your Images: Utilize panoramic imaging techniques by taking multiple shots from various angles without moving the camera. Ensure each image overlaps by about 20% to aid in accurate stitching. Always photograph in portrait mode to capture the subject’s full height.
Step 3: Install and Run Agisoft Photoscan: Download and install Agisoft Photoscan. Open the software and proceed with creating your 3D model.
Step 4: Import and Process Images: Go to “Workflow,” click “Add Photos,” and select all your images. Then, choose “Align Photos” under the Workflow menu. Set “Generic Preselection” to off, accuracy to “Highest,” and adjust the “Keypoint Limit” and “Tie Point Limit” as needed. Click “OK” to start processing. The time taken will vary based on your computer’s performance and the number of images.
Tips for Troubleshooting
If you encounter issues with Agisoft Photoscan, such as unclear images or incorrect camera placements, try renaming your files to more descriptive names and reconstructing the model. Additionally, re-aligning the photos by adjusting the “Pair Preselection” setting to “Generic” can improve the accuracy of camera positioning and image overlap.
This guide offers a streamlined approach to creating 3D models using Autodesk 123D Design and Agisoft Photoscan, making the process easier and more effective.
