Real Time Check

Real Time Check is a component providing a real time feedback evaluation of the aesthetic properties under investigation. If the user wants information about the quality of the current shape, he may use the display of some evaluation lines that are shown in real time while moving the mouse. Evaluation lines are shadow lines, sections and isophotes. They can be displayed for different light directions by numerical input or mouse. 

Example

Push-Pull

Push-Pull is a function for modifying curves. It consists of a circle deforming and smoothing the shape. It can be either invoked directly for modifying a selected entity-curve or in the Change Shadow Line functions to change the look of given shadow lines on the surface. Fundamental operations are:

     - Pushing: dragging the tool against the curve, and all touched parts will be pushed away.

     - Pulling: all parts of the curve inside the circle will be pulled when dragging the mouse.

     - Smoothing: all parts of the curve inside the tool will be smoothed when dragging the mouse.

Example

Shadow Lines Modification

The user has the possibility of displaying shadow lines on a surface and changing one of the shadow lines, then a new surface is created, having the modified line as shadow line. Modification of the surface occurs by respecting geometric continuity conditions as specified by the user. The SLM method is based on two different aproaches: one leads to a global modification of the whole surface, while the second one is based on FdF deformation function, modifying a single patch or the overall shape.

The new shadow line can be obtained through three differnt creation methods:

     - CBP method: creation of a Bezier curve through its control points.

     - Cv method: selection of an already existing curve.

     - PuPu tool: modification of the shadow line by means of the Push & Pull tool.

FdF tracking

The FdF Tracking tool can be used for the modificaton of surface areas under quality and continuity constraints. The modification starts from a initial surface. The user specifies the shape modification domain (a complete surface, a patch or a sketched poligonal domain in the surface) and the continuity constraints between the modified area and the surrounding surface (G-1, G0, G1, G2). The part of the surface inside the domain is interactively modified though user handles (points, curves, normal vector and tangent plane).

Step Tool

A Step-like is an intrusion or extrusion having a shape with an evident longitudinal predominance that can be naturally associated to a curve (the mapping wire).

The step operator performs the substitution of a region crossing one or more adjacent surfaces with two or more surfaces joined at the mapping wire with specified continuity conditions. 

The smoothness of the resulting surfaces can be defined by specifying continuity constraints between the modified area and the surrounding surface (G-1, G0, G1, G2).
