Getting Started
The following steps will guide you through a simple modeling process of a traditional Chinese Vase:

Basic Operations. In order to use 3-Sweep like a charm, you should learn and use the 4 modes in this software. They are: Modeling Mode: This is where the 3-Sweep magic happens, select a mesh type from toolbar: and draw on the canvas. Manipulating Mode: You can translate, scale or rotate your model here. Viewing Mode: This mode is for moving the camera so that you can view the model in. The full Fifth Circuit Court of Appeals on Friday found that the so-called net worth sweep—in which the Federal Housing Finance Agency directs Fannie Mae and Freddie Mac’s profits to the U.S. Treasury—exceeds FHFA’s statutory authority as the GSEs’ conservator. It also found that the agency’s structure—led by a single director.
- Modeling Mode : This is where the 3-Sweep magic happens, select a mesh type from toolbar: and draw on the canvas.
- Manipulating Mode: You can translate, scale or rotate your model here.
- Viewing Mode: This mode is for moving the camera so that you can view the model in different angles. Click on to restore camera to its original location.
- Border Edit Mode: Normally the edge of the image is detected automatically using existing algorithms. You can, however, edit the edge/border of image yourself with the four tools provided.
Besides, you can switch between the 4 display modes of your image:

- Modeling.InnerRange: Low bound percentage of search beam when finding the radius of next level based on the previous level of our generalized cylinder.
- Modeling.OuterRangeBase: Up bound percentage of search beam.
- Modeling.SampleFrequency: Sampling frequency in image space when determining the radius of mesh.
- Modeling.BendingMesh.MaxBendAngle: Maximum bending angle when drawing the bending part of a mesh. This regularizes users' drawing.
- Texture.TextureExtrapolation: If enabled, the texture on the boundary of your mesh will be automatically synthesized and extrapolated. (Otherwise part of the background maybe visible on the mesh)
- Texture.ExtrapolationLength: The length of extrapolation.
- EdgeDetection.SnappingPenTool.Threshold: Canny threshold when using snapping pen tool.
- EdgeDetection.SnappingPenTool.AutomaticConfirmBorder: Controls whether the border is automatically saved when exiting border edit mode. Otherwise you will have to click on every time you make changes to the detected edge image.
- EdgeDetection.COBUpdateServer:

FAQ
3 Sweep Machine
- Q: Why are the demos a little bit different from paper video?
- A: Three main reasons: (1) There are too many parameters (e.g. Modeling Options, Optimization Constraints...) to play with in the algorithm and we cannot guarantee that these numbers exactly match the paper; (2) The trajectories of mouse are much more casual in the demo. (3) The edge extraction method is different and the implementation is modified for more general use cases (e.g. we will not add constraints automatically). It should be noted that better results can be achieved with precise drawing and more dedicated parameter tuning process; we hope you can explore these things yourself!
- Q: Will the code be released in the future?
- A: Sadly but no. We can help port the application to Mac/Linux if possible.
- Q: I cannot draw anything on the canvas. When I load in a picture the canvas is still black.
- A: You can create a file named
gl.txt
in the same folder with the program to specify the rendering technique you would like to use. If you are using outdated hardware which does not support OpenGL or are experiencing compatibility issues, please entersoftware
ingl.txt
to use Mesa as your software-based OpenGL simulator. Otherwise the program will automatically detect suitable hardware as the rendering backend. If you have dual graphics card, please consult your admin on how to switch to the hardware you want. - Q: I can draw objects normally but I cannot select objects nor take snapshots - what's wrong?
- A: Anti-aliasing mode is currently experimental and some graphics card may have weird behaviors. Simply disable anti-aliasing mode by
