Front This panel is used to project the surface triangulation (front) onto a set of surfaces, and this process can be divided into five steps: (1) read the front using the "IO" panel, (2) turn the appropriate patches on, (3) turn associated surfaces on, (4) project the front onto the surfaces, and (5) check for the validity of the new triangulation. In order to have a successful projection, users are required to insure that: (1) the surface triangulation is close enough to the associated surfaces, and (2) the associated surfaces have sufficient display paths. FAQ How do I read an unstructured surface grid in? Use the I/O panel to read the grid as VGRID front or a FELISA Front How do I project the front? Turn the desired surfaces and triangulated patches on, and press Project button How do I undo a projection? Turn the triangulated patches on, then press Undo button How do I undo a projection after the front files are updates? Read the projected front in and update the front from I/O panel. How do I check the projected surface grid? dmax shows the maximum distance the front has moved. Select a positive number, d < dmax, in the Distance input-field, this will display the triangles that have moved a distance between d and dmax (i.e., triangles that have vertices that have moved by at least a distance d). How do I keep the boundaries from projection? Push the Project Boundary button How do I turn on/off an individual patch? Select the patch by from Patch Number input-field, then press the Front On/OFF button How do I turn on/off a family of patches? Select the family, then press Turn On/Off Family The project grid is messed up, how can I fix it? Quality of surface projection depends on the surface parameterization. You can fix your problem by either increasing the display path of the NURBS surfaces changing the project speed activate the Projection Properties panel make the surfaces active (one at a time) change the speed (input field speed) to 1
