Menu Structure: Window

The Window button provides the users with additional information. It includes the following items: Display & Tracing Options, Partition of Unity, Triangular Computing Scheme, Hodograph (First Derivative), Second Derivative, Change Color Scheme and Profile Instances Control. Selecting one of these items opens the corresponding window.

• Display & Tracing Options
  This will brings up the Display & Tracing Options Window for various display options. See The Display & Tracing Options Window for the details.

• Partition of Unity
  This will bring up the Partition of Unity Window, which displays the partition of unity by the basis functions at the current value of u. See The Partition of Unity Window for the details.

• Triangular Computing Scheme
  This will bring up the Triangular Computing Scheme Window, which provides a detailed step-by-step computation of de Casteljau's algorithm if the current curve is a Bézier curve. Otherwise, it displays the stepwise computation of de Boor's algorithm. A detailed discussion is in Tracing the Curve - de Casteljau's and de Boor's algorithms.

• Hodograph (First Derivative) and Second Derivative
  This will bring up the Hodograph (First Derivative) Window and Second Derivative Window, respectively. The use and meaning of these two windows can be found in The Hodograph (First Derivative) Window and Second Derivative Window and The First Derivative (Hodograph) and Second Derivative Curves.

• Change Color Scheme
  This window is for changing the colors used to display various objects. See Changing the Color Scheme for the details.

• Profile Instances Control
  This window is only useful in Cross Section Design and is in a very experimental stage. It may disappear or be modified in future versions. See The Profile Instances Control Window for additional information and Using Skinned Surfaces to Design Swept Surfaces for its use.
