3 sweep software download
3 sweep software is based on a research paper by Tsinghua University, Tel Aviv University, and The Interdisciplinary Center that was presented at SIGGRAPH ASIA 2013. The paper proposes a novel technique that uses three strokes (sweeps) to define the shape of an object in an image. The first sweep defines the main axis of the object, the second sweep defines its cross-section profile, and the third sweep defines its depth. The system then reconstructs a 3D mesh that matches the input strokes and the image edges.
Some of the features of 3 sweep software are:
Efficient: It can create instant 3D models from single images.
Accurate: It uses detected picture edges to guide modeling.
User-Friendly: It has an intuitive and easy-to-use user interface.
Creative: It allows you to edit the model by bending, scaling, rotating, or adding constraints.
Realistic: It can assign texture to the model using automatic foreground removal and patch-match algorithm.
In this article, we will show you how to download and install 3 sweep software on your Windows 10 computer, how to use it to create 3D models from single images, how to texture and export your models, and some tips and tricks for better modeling results. We will also provide some examples of 3 sweep modeling from different images. By the end of this article, you will be able to create your own 3D models from single images using 3 sweep software.

Now that you have installed 3 sweep software on your computer, you can use it to create 3D models from single images. The software has four modes: modeling, manipulating, viewing, and border edit. Each mode has a different function and interface. You can switch between the modes by clicking on the buttons at the top of the screen. In this section, we will explain each mode and how to use it.
Basic Operations
Before we go into the details of each mode, let us first introduce some basic operations that are common to all modes. These operations are:
Open Image: To open an image file, you can either click on the File menu and select Open, or drag and drop the image file to the canvas. The supported image formats are jpg, png, bmp, and tif. You can also use the demo images that come with the software by clicking on the Demo menu and selecting one of them.
Save Model: To save your model as an obj file, you can either click on the File menu and select Save As, or press Ctrl+S. You can also save your model as an image file by clicking on the File menu and selecting Save Image.
Undo/Redo: To undo or redo your last action, you can either click on the Edit menu and select Undo or Redo, or press Ctrl+Z or Ctrl+Y.
Help: To access the user manual, you can either click on the Help menu and select Manual, or press F1. The user manual contains detailed instructions and examples of how to use 3 sweep software.
Modeling Mode
The modeling mode is the main mode of 3 sweep software. It is where you perform 3 sweep operations on the canvas to create 3D models from single images. The modeling mode has two sub-modes: sweep 1 and sweep 2/3. You can switch between them by pressing Tab.
In sweep 1 sub-mode, you define the main axis of the object by drawing a stroke along its length. The stroke should start from one end of the object and end at the other end. You can adjust the stroke by dragging its endpoints or control points. You can also change its color by clicking on the color picker at the bottom of the screen.
In sweep 2/3 sub-mode, you define the cross-section profile and depth of the object by drawing two strokes perpendicular to the main axis. The first stroke defines the cross-section profile, which is the shape of the object when cut along its main axis. The second stroke defines the depth, which is how far the object extends along its main axis. You can adjust both strokes by dragging their endpoints or control points. You can also change their colors by clicking on the color pickers at the bottom of the screen.
After drawing both strokes, you will see a 3D mesh that matches your input strokes and image edges. You can refine your model by using bending operation or adding constraints and optimization. Bending operation allows you to bend your model along its main axis by dragging a control point on it. Constraints and optimization allow you to add coplanar, parallel, or perpendicular constraints to your model and optimize it to fit better with image edges.
Manipulating Mode
The manipulating mode is where you translate, scale, or rotate your model. You can switch to this mode by clicking on the Manipulating button at the top of the screen or pressing M.
In this mode, you will see a coordinate system with three axes: X (red), Y (green), and Z (blue). You can use this coordinate system to manipulate your model in three ways:
Translate: To move your model along an axis, you can drag one of its arrows with your mouse. To move your model freely in any direction, you can drag its center point with your mouse.
Scale: To resize your model along an axis, you can drag one of its cubes with your mouse. To resize your model uniformly in all directions, you can drag its center cube with your mouse.
Rotate: To rotate your model around an axis, you can drag one of its circles with your mouse. To rotate your model freely around any point, you can press Alt and drag anywhere on the canvas with your mouse.
Viewing Mode
The viewing mode is where you move the camera and view your model in different angles. You can switch to this mode by clicking on the Viewing button at the top of the screen or pressing V.
In this mode, you can use your mouse and keyboard to control the camera and view your model from different perspectives. Here are some of the commands you can use:
Left Mouse Button: To rotate the camera around the model, you can press and drag the left mouse button on the canvas.
Right Mouse Button: To zoom in or out, you can press and drag the right mouse button on the canvas.
Middle Mouse Button: To change the field of view and orientation of the model, you can press and drag the middle mouse button on the canvas.
Arrow Keys: To move the camera up, down, left, or right, you can use the arrow keys on your keyboard.
Home Key: To reset the camera to its default position, you can press the home key on your keyboard.
Border Edit Mode
The border edit mode is where you edit the edge or border of the image. You can switch to this mode by clicking on the Border Edit button at the top of the screen or pressing B.
In this mode, you will see a yellow line that represents the border of the image. You can use four tools to edit this border: add point, delete point, move point, and smooth point. You can select a tool by clicking on its icon at the bottom of the screen or pressing its corresponding number key (1-4).
Add Point: To add a point to the border, you can click on an empty spot on the border with this tool selected. A new point will be created and connected to the nearest points.
Delete Point: To delete a point from the border, you can click on an existing point on the border with this tool selected. The point will be removed and the border will be updated.
Move Point: To move a point on the border, you can click and drag an existing point on the border with this tool selected. The point will be moved and the border will be updated.
Smooth Point: To smooth a point on the border, you can click on an existing point on the border with this tool selected. The point will be smoothed and the border will be updated.
Editing the border of the image can help you improve your modeling results by removing unwanted background or foreground elements from your image. You can also use this mode to create holes or cutouts in your model by editing the border inside your model.
How to Texture and Export the Model
After creating your model in 3 sweep software, you may want to texture it and export it as an obj file. Texturing is the process of applying an image or color to your model to make it look more realistic. Exporting is the process of saving your model as an obj file that can be opened by other 3D software or applications.
To texture your model in 3 sweep software, you need to use two algorithms: automatic foreground removal and patch-match. Automatic foreground removal is an algorithm that removes the background of the image and assigns the foreground to the model. Patch-match is an algorithm that finds the best matching patches between two images and fills in the gaps or holes in the model. These algorithms are implemented in 3 sweep software and can be applied by clicking on the Texture button at the top of the screen or pressing T. To texture your model in 3 sweep software, you need to follow these steps: 1. Click on the Texture button or press T to enter the texturing mode. You will see a window that shows the original image, the model, and the texture map. 2. Adjust the parameters of the automatic foreground removal algorithm by using the sliders at the bottom of the window. The parameters are: alpha, which controls the transparency of the foreground; beta, which controls the smoothness of the foreground mask; and gamma, which controls the edge weight of the foreground mask. You can also use the eraser tool to manually remove some parts of the foreground or background. 3. Click on the Apply button to apply the automatic foreground removal algorithm to your model. You will see that the background of the image is removed and only the foreground is assigned to your model. 4. Adjust the parameters of the patch-match algorithm by using the sliders at the bottom of the window. The parameters are: patch size, which controls the size of the patches used for matching; iterations, which controls how many times the patch-match algorithm is run; and alpha, which controls how much blending is applied to the patches. 5. Click on the Apply button to apply the patch-match algorithm to your model. You will see that any gaps or holes in your model are filled with patches from the original image. 6. Click on the OK button to confirm your texturing result and return to the main interface. You have successfully textured your model in 3 sweep software. Now you can export your model as an obj file by clicking on File > Save As or pressing Ctrl+S. You can also save your model as an image file by clicking on File > Save Image. Tips and Tricks for Better Modeling Results
3 sweep software is a powerful and creative tool for 3D modeling from single images, but it is not perfect. Sometimes, you may encounter some problems or challenges when using it, such as poor image quality, inaccurate modeling, or unrealistic texturing. To help you overcome these issues and achieve better modeling results, here are some tips and tricks that you can use:
Choosing the Right Image
The quality and suitability of the image that you use for 3 sweep software can have a significant impact on your modeling results. Therefore, it is important to choose the right image that meets the following criteria:
Clear Edges: The image should have clear and sharp edges that define the shape of the object. This will help the 3 sweep software to detect the image edges and guide the modeling process. Avoid images that have blurry, noisy, or jagged edges.
Simple Background: The image should have a simple and uniform background that contrasts with the object. This will help the 3 sweep software to remove the background and assign the foreground to the model. Avoid images that have complex or cluttered backgrounds that interfere with the object.
Good Lighting: The image should have good lighting that illuminates the object evenly and reveals its details. This will help the 3 sweep software to assign texture to the model and make it look realistic. Avoid images that have poor lighting that causes shadows, reflections, or glare on the object.
Adjusting the Perspective and Orientation
The perspective and orientation of the image that you use for 3 sweep software can also affect your modeling results. Therefore, it is important to adjust them to match your desired view of the model. You can use the middle mouse button to change the field of view and orientation of the model in 3 sweep software. Here are some tips on how to use it:
Field of View: The field of view is the angle of vision that determines how much of the scene you can see. You can change the field of view by pressing and dragging the middle mouse button horizontally on the canvas. A larger field of view will make the scene look wider and more distorted, while a smaller field of view will make the scene look narrower and more realistic.
Orientation: The orientation is the direction that determines how the model is aligned with respect to the image plane. You can change the orientation by pressing and dragging the middle mouse button vertically on the canvas. A positive orientation will make the model face upward, while a negative orientation will make the model face downward.
Adding Constraints and Optimization
Another way to improve your modeling results is to add constraints and optimization to your model. Constraints are rules that specify the geometric relationships between different parts of your model, such as coplanar, parallel, or perpendicular. Optimization is a process that adjusts your model to fit better with the image edges. You can add constraints and optimization to your model by clicking on the Constraint button at the top of the screen or pressing C.
In this mode, you will see a window that shows the original image, the model, and the constraint list. You can use three tools to add constraints to your model: coplanar, parallel, and perpendicular. You can select a tool by clicking on its icon at the bottom of the window or pressing its corresponding number key (1-3).
Coplanar: To add a coplanar constraint, you need to select two faces of your model that are supposed to be on the same plane. You can do this by clicking on them with this tool selected. A green line will appear between them to indicate the constraint. A coplanar constraint will make the two faces lie on the same plane.
Parallel: To add a parallel constraint, you need to select two edges of your model that are supposed to be parallel. You can do this by clicking on them with this tool selected. A blue line will appear between them to indicate the constraint. A parallel constraint will make the two edges parallel to each other.
Perpendicular: To add a perpendicular constraint, you need to select two edges of your model that are supposed to be perpendicular. You can do this by clicking on them with this tool selected. A red line will appear between them to indicate the constraint. A perpendicular constraint will make the two edges perpendicular to each other.
After adding constraints to your model, you can apply optimization by clicking on the Optimize button at the bottom of the window. Optimization will adjust your model to fit better with the image edges and respect the constraints that you have added. You can also adjust the parameters of optimization by using the sliders at the bottom of the window. The parameters are: lambda, which controls how much weight is given to image edges; mu, which controls how much weight is given to constraints; and iterations, which controls how many times optimization is run.
Click on OK button to confirm your constraints and optimization results and return to the main interface.
