MODELING OPERATIONS |
Our system supports the following modeling operations (similar to FiberMesh):
Figure 2: Initial Model Creation. The user draws a closed 2D curve, and the system automatically generates an initial model from the curve. Figure 3: Adding Control Curves. The user can add a control curve to the model by directly drawing it on the surface of the model. Figure 4: Erasing Control Curves. The user can use the eraser tool to remove part of a control curve. Figure 5: Dragging. The user can directly change the shape of the model by dragging the control curves. Figure 6: Cut. The user can firstly draw a curve crossing the model, and then draw a curve from inside to outside the model to cut off part of the model. Figure 7: Extrusion. The user can firstly add a closed curve to the model, and then draw an outline of extrusion to create a new part on the model. Figure 8: Changing Curve Type. The user can change a smooth curve into a sharp curve or vice versa. |
