Picking

Picking is a special way of viewing Gauss Points presentations

Picking mode is activated by selecting   button in the Gauss Viewer toolbar.

Now if the cursor touches a point it is highlighted  with triangular markers (pyramids). The cursor is dynamically generated so that apexes of each pyramid touch the point sprite boundary, and the height of the pyramid is fixed.

To get information about the point click the left mouse button or press S (or s) key of the keyboard.

Once a point is selected, the presentation is centered around this point and a semi-transparent window is displayed next to the selected point and shows the following information:

• The ID of the point within its parent mesh element

• Coordinates of the Gauss point

• In the case of a result at Gauss point: Scalar value being inspected + all components individually

• Name of its parent mesh element

In addition, the active scalar bar is updated to highlight the corresponding value of the selected scalar value by a black line.

All Picking preferences can be defined using Preferences, however, you can customize them for the current presentation.

• Cursor - allows to adjust the Size of the cursor used for Picking (ranging from 0.1 to 1), the Height of the pyramids (ranging from 0 to 10) and the Selection cursor color.

• Tolerance - defines at which distance of the cursor from the point it becomes selected (ranges from 0.001 to 10).

• Information window - allows to define the Transparency (from 0% = opaque to 100% = transparent) and Position of the window, which can be:

• Centred below the point, or

• located at Top-left corner of the 3D view

• Movement of the Camera can also be define by the user.

• Zoom at first selected point - This value is used to define the focal distance at the first selected point (at the end of the movement of the camera). This value is a ratio that will be multiplied by the current zoom value.

• Number of steps between two positions - defines the smoothness of camera movement at selection by the number of iterations. If set to 1 the camera is zoomed and centered at the point momentarily. Greater numbers mean very slow camera movement.   

• Display parent mesh element - allows to visualize or hide the parent mesh element of the selected gauss point.
