Part: User Interface of JavaView

Chapter: Inpectors

Section: Infopanels

Subsection: Infopanel of Element Sets

Surfaces in JavaView are point sets with additional information about the elements (filled polygons) that form it. Each element (e.g. triangle, quadrilateral) is defined by the set of points that have to be connected. The ordering of vertices in the definition of an element determine its orientation (i.e. direction of its normal vector).

Author Information, Description and Name
These are described in the Introduction to Infopanels.
Vertex Information
Is already described in the Infopanel of Point Sets.
Element Information
Number of Elements Displays the current number of elements in this element set. Changing the value and pressing Enter removes or adds elements at the end of the array.
Vertices per Element Displays the number of points that are connected by each element (if the elements have different number of points, this fact is displayed here instead). So, a value of 3 means that all elements are triangles, a value of 4 means that all elements are quadrilaterals, and so on.
Index Activate a checkbox to mark the element with the given index. Deactivate to unmark the element.
Connectivity Information 0 1 2 ... Each horizontal row of numbers describes which vertices are connected to an element (and the order determine its orientation). Vertices are referenced by their index in the vertex array. If you change anything type Enter to make the change effective.
C Every element can have additional information attached to it. You can edit this information by clicking on this button. The information is not yet saved in jvx or other file formats, you need to save a serialized geometry.
