Mode Select


These radiobuttons and optionmenus are used to set the editing mode of the GUI. The "Mode Select" radiobuttons are the master selection, and the other widgets specify sub-modes. The behavior in each of the four master modes is explained below. A summary can be found in the tables of the behavior of the M1  and M3 mouse buttons in the orthogonal views.

Select

In the select mode, existing objects may be selected and their positions, dimensions and orientations varied. To select a single object, deselecting all others, click it with M1. To add or remove items from the selection, click them with M3. To add all items in a region to the selection, press and drag M1 to define the region (rubber-band selection). Using Shift-M1 instead, the enclosed items will be subtracted from the selection.
 

Zoom

In the Zoom mode the orthogonal views may either be: To scale up ("zoom in"), click and drag M1 in any orthogonal view. A rectangle will be drawn having the pointer position where M1 was originally clicked and the current pointer position as opposite vertices (rubber-band selection). When M1 is released, the area enclosed by the rectangle is expanded to fill the orthogonal view. The other orthogonal views are scaled up by the same amount. If the rectangle does not have the same aspect ratio as the orthogonal view, the scaling factor is defined by the dimension that implies the least change in the size of the image.

The procedure for scaling down ("zooming out") is the same except that the "shift" key should be depressed when M1 is clicked. You do not need to keep the "shift" key depressed as you drag the mouse. The orthogonal views are scaled down so that the area currently filling the complete view now fills the rectangle delineated with the mouse.

The zoom operation should not affect the rendered image, either in the dimensions of objects or the scaling of textures. The TSIPPwb is aware of how far you have zoomed in or out from the nominal position, and scales all dimensions before using TSIPP to render the image.  When frames are fixed, the dimensions are normalized so that zooming will not affect the interpolation process during recording. When you revisit a frame, or use the << and >> buttons, the frame will revert to the nominal scale.

Create

In this mode a new object may be created. The type of the object is specified by the "Object Type" optionmenu, which is only enabled when the Create mode is selected.
Depending on which one of the options Cuboid, Ellipsoid, Cylinder, Cone, SpotLight, PointLight or Freehand is selected, an object of that type will be created when M1 is used on any one of the orthogonal views.

Model

In this mode a freehand object may be modelled to create an arbitrary shape. First, the modelling tool is defined. There must be only one object selected and it must be of type Freehand. M1 is used to define a region. The precise meaning of this depends on the tool. A modelling handle will appear as a small red filled circle. This may be dragged with M1. Note the following about Freehand objects: There are currently two options for the modelling tool. Both of them are defined by an elliptical rubber-band:
