View Control Bar

The View Control Bar is docked to the right side of the view window in the default configuration. You can open and close it from the 'View/ViewControls' pull down menu or using the F5 hotkey. If the contents of the view control bar do not fit inside the visible area, you can scroll it by dragging it with the right mouse button 'Ctrl' key held down, or with the middle mouse button.

You can open a popup menu from the left border of the view control bar. With the menu, you can turn icon labels on and off, and control the visibility of the view control groups.

The target selector gadget selects the modify target for the Camera group controls below the selector gadget. The following targets are available:

  • View
  • Input plane
  • World orientation
  • Selected objects
  • Texture maps of selected objects

Camera Group

The Camera group contains four icons which control the orientation and position of the selected target. Use the icons by pressing the left mouse button down on top of an icon and moving the mouse LMB held down. The icons are (in up to down or left to right order):

  • Rotate:Rotates the selected target.
  • Zoom:Changes the camera scale / resizes the selected target.

Interactor Group

The common nominator of the tools in the Interactor group is that after a tool has been selected, the program expects some mouse clicks (or LMB dragging) on the view window. The tools are:

Orientation Group

The Orientation group contains tools which set predefined orientations for various view window related items. Most of these tool icons have also a side menu which opens with a LMB click. The side menus contain some additional variations of the tools.

Front: This tool puts the view camera to the front view orientation. The camera will look against z axis (heading 180 degrees, pitching zero). The camera is rotated to the front view about its aimpoint. Also the input plane is rotated so that its normal matches the z axis. Shift clicking the icon gives the opposite view (the back view).

The side menu has two additional versions: 'View' and 'Input Plane'. These tools rotate the view camera or the input plane only. Note, however, that all the three versions perform the same task when the camera and the input plane are locked together.

Side: The side view tool. Side view is the view from the left side of the object (along positive x axis). The side menu is similar to the front view above. Shift clicking the icon gives the opposite view (the right side view).

Top: The top view tool. View camera and input plane are rotated so that the camera looks down against y axis. See the front view tool above for the side menu explanations. Shift clicking the icon gives the opposite view (the bottom view).

Reset: Resets the view back to the 'Native state' that has been stored into it. This usually changes camera and input plane positions and orientation, as well as the zoom scale. The side menu has three entries:

Fit: The autofocus tool. The view camera is aimed at the center of the selected objects and zoomed/moved so that the selected objects fill about 75% of the view window. Also the clipping range is adjusted so that all selected objects become visible. Shift-clicking the tool focuses on the selected edit handles, when the selected objects are set to editing state.

Fetch: Fetches the view camera orientation from the selected object. The view will be moved to its position and rotated to match its object space. For example, you can take the view from a camera object or from a spot light this way. The side menu is the following:

Sync IP: Rotates the view camera so that it is orthogonal to the input plane. This tool may be useful when using a disconnected camera-input plane system. The attached menu is the following:

Canvas Group

Persp: Sets perspective projection for the view on/off. The parallel camera projection is often more suitable for accurate modeling purposes.

Draw: Enables and disables snap grid drawing. A grid must be selected before it can be drawn.

Snap: Enables and disables grid snapping. A grid must be also assigned for the view, otherwise snapping does not work. You can assign the grid by drag and dropping it from the select window into the view window, or using the view property window.

OpenGL: Activates real time drawing via the OpenGL interface. By default, it renders shaded surfaces, but you can change the options from the view property window. OpenGL is a faster alternative than Windows GDI drawing if a modern graphics accelerator is available.

Windows: Selects Windows GDI drawing which is always in wireframe mode. GDI drawing is not hardware dependent and a safe alternative if OpenGL driver compatibility problems appear.

Ray Trace: Ray trace renders the view window.
