Surface Smoothness

Calling the command:

This command allows evaluating regularity of the model.

This type of rendering allows to visually determine whether the adjoining faces are connected smoothly with tangency transitions, or with continuous transition of curvature.

If all surfaces adjoin tangentially, then the texture stripes appear continuous, although may sharply change the direction. If the surfaces have smooth transition with continuous curvature, then the texture stripes are not just continuous, they also transit smoothly.

Right after entering the command, the model coloring changes. By default, it will be a two color pattern. You can change the color to one color lines or specify the format file yourself .bmp, .jpeg, .gif, or .png containing the image used to display the smoothness of the model.

The color used for one color or two color stripes is set using the Color 1 and Color 2 fields.

The width, relative width, the rotation angle of the stripes and accuracy of their rendering are also defined in the parameters window.

You may find the default pattern most convenient. In this way, the higher is the curvature, the finer are the stripes of the pattern applied on the model. The colored stripes are widest on flat faces.

The stripes that paint the faces can be drawn in different directions. However, if the faces adjoin smoothly in terms of continuous tangency, the stripes are neither interrupted nor shifted with respect to each other, but can sharply change the direction. If the faces connect smoothly with continuous curvature, the stripes are not interrupted and smoothly change the direction.

Rendering of the colored stripes in the 3D window is noticeably affected by the parameter Mesh Quality, defined on the 3D tab in Document Parameters. We recommend using highest accuracy of the mesh quality when examining the model regularity.
