Viewer Release 210

The Animator4 Viewer is based on the kernel and the graphical user interface of Animator4It can be used to import simulation datasets prepared with Animator4 and allows a limitedinteraction with the imported datasets Animator4 Viewer can change datasets create new setsor delete them

This guide is mainly based on an exemplary dataset (Cana4db) which can be be downloadedfrom httpgns-mbhcomid=ViewerExample

IMPORT DATA

Animator4 Viewer can be used to import databases generated by Animator4 The main focus isto use datasets stored in the database4 format (ldquoa4dbrdquo) Nevertheless Animator4 Viewer canalso read the a3 database files for compatibility reasons Please note that you can only importone database at a time and that the import is limited to the full dataset ie it is not possible toimport subsets of a database

Upon every startup Animator4 Viewer will open a file dialog which can be used to locate thedatabase file You can access the open dialog at any time from the menu bar

bull Select the database4 file (Cana4db) in your download directory and click the buttonldquoChooserdquo button

HANDLE VIEWS

Animator4 Viewer can handle multiple views to compare models from different perspectivesand different states or to observe multiple curves simultaneously Animator4 Viewer supportsall of the five different Animator4 view types Model curve video image flc and presentation

For each type an unlimited number of views can be created

bull To add a second model view select the menu entry Windows Add View ModelView from the menu bar

bull To switch between the views open the menu entry Windows in the menu bar All existingviews will be listed in this menu Select one of the views from the list to get this viewinto the foreground

You can also arrange all views in the workspace of Animator4 Viewer

bull Open the menu Windows Arrange Views from the menu bar Select one of theentries for example ldquoHorizontal Tilerdquo to arrange the views

CONTROL MODEL DATA

31 Camera Control

You can control the geometry data in the model view by using either different input deviceslike the mouse or a spaceball or by using the View dialog (Model View) to translate rotateor scale the view

All translations and rotations in Animator4 Viewer are defined in screen coordinates with thex-axis in horizontal direction the y-axis in vertical direction and the z-axis in the directionperpendicular to the screen surface The dynamic rotation center is located on the node nearestto the mouse pointer If the mouse pointer is outside of the model the rotation center is set tothe middle of the model view

The global coordinate system can be used to check the position of the model It is located inthe lower left corner of the model view

311 Using Mouse Control

To control the camera position with the mouse hold down the left Ctrl-key move the mouseand press the

left mouse button to rotate about the rotation centermiddle mouse button to move along xy axisright mouse button to rotate about z axisleft + middle button or use the mouse wheel to zoom in and out

Note The view can always be centered and fit to the window using Ctrl-F9

Viewer Release 210

You may use the Shift-key instead of the Ctrl-key to change the view in the wireframe-likeldquoedge moderdquo where only the edges of your model are drawn during the change of view Thismode reduces the rendering work significantly so the handling of very large models will bemuch more user-friendly

312 Using the View dialog

The View dialog can be used for changing the parameters of the camera to specific values Toopen the View dialog select Model View from the menu bar

The upper part of the dialog shows the current view parameters The values will be dynam-ically updated if you change the view by using either shortcuts or keyboard and mouse Theparameters in the View dialog can be changed by hand as well but wonrsquot be executed until theldquoApplyrdquo button will be clicked

To adjust the view properly it is necessary to understand some backgrounds of categories givenin the View dialog A detailed description is either given in the Animator4 Reference Manualor User Guide

32 Handle Model Data

321 Slot Selector

Animator4 Viewer can handle multiple datasets in a single session to efficiently compare vari-ants or to show different attributes of one model at the same time Multiple datasets are orga-nized into slots in Animator4 Viewer each slot can independently hold geometry data as well

10 Chapter 3 Control Model Data

Viewer Release 210

as displacements and other results You can control the visibility of slots using the slot managerin the command area

To colorize all items of one slot in the same color click the color button in column ldquoCrdquo Thishelps to associate items with a slot when working with multiple slots

bull To toggle between uniform and standard colors activate or deactive the color button incolumn ldquoCrdquo

You can easily toggle the visibility state of single slots using the slot selector

bull To toggle the visibility of a model activate or deactivate the switch in column ldquoVrdquo

322 Interaction Modes

The methods of selection given above can be used to interact with the items in the model viewYou have erased some items before You can further identify colorize or stylize items Theinteraction mode can be set with the Mouse Control toolbar as given in the picture below

Select Item

Identify Item

Erase Item - Activated

Stylize Item

The interaction modes available in Animator4 Viewer are explained in the following

bull Select

Selected items are highlighted and can be used for the operations erase and identify Youcan access these operations by using the context menu which changes its menu entrieswhen in selection mode You can use the Reset Selection entry of this selection modecontext menu to reset your selection or simply revert a selection by clicking a selecteditem again

bull Identify

The selected items are highlighted and marked with their ID-number The identificationmarkers can be deleted by using the toolbar menu Identify Reset or by clicking onthe selected items again

32 Handle Model Data 11

bull Erase

Selected items are erased (hidden) from the model view Erased items can only be re-added together To re-add them right-click into the model view and select Add All oruse the Common utils toolbar button ldquoAdd Allrdquo button

bull Stylize

Selected items are stylized using the style selected in the Mouse Control toolbar

323 Item Filters and Actions

One task when working with Animator4 Viewer is to select items and to apply actions on themThis chapter will introduce the basic graphical selection methods available

In order to test the selection modes you have to activate one of the action modes in the Resultstoolbar

Item Filters

Graphical selection is based on three selection modes

bull PointampClick You can select single items in ldquosinglerdquo selection mode Simply click onthe item you want to select with your left mouse button

bull Rectangular Window

You can select multiple items located in a rectangular area by using the ldquorectangularrdquoselection mode Initiate the window selection mode by pressing the left mouse button atthe position on screen where you want the rectangular area to start Hold this button anddrag the mouse to draw the rectangular area All items within this rectangular area willbe selected

bull Polygon Window

To have a more precise control over the items to be selected you can use ldquopolygonrdquowindow selection To activate this selection mode first click the left mouse button Holdthe left mouse button and additionally click the right mouse button to set the first pointof the polygon Release all mouse buttons and set additional points by clicking the leftmouse button If you want to remove the last segment of the polygon press the middlemouse button If you have finished drawing the polygon press the right mouse button toconfirm selecting the items within the polygon area

bull Reset Selection

To reset your selection you can either press the Esc-Key or use the Reset Selection ofthe context menu in the model view
