Render Window Commands

If you press and hold the right mouse button down with the cursor in the window, a pop-up menu appears which contains commands for interacting with the display. Most of these commands interact with the mouse, following the movement regardless of whether a mouse button is pressed down or not. Clicking the right mouse button again finishes the execution of a command.

If you need to change the cursor location during some command, press the Ctrl-button when moving the mouse and the mouse movement won't affect the image.

The various functions are explained here:

If you hold the middle mouse button down, up and down mouse movement zooms into and out of the object.

End the function with the right mouse button.

Note: If your model is very large, or the machine is slow, you should set the Move Mode (below) to the Box option. This gives much better interaction than waiting for the shaded image to be continuously updated.

  • Move Light - The command moves a light around the object. Horizontal mouse movement moves the light horizontally around the object, and vertical movement moves up and down.

Þ Light number

If there are more than one light point, you may select the light you want to move from the command's sub menu.

  • Move Mode - This command controls how the shaded object is updated with camera and light movements. It has two options. The current option is displayed in gray, while the other option (which can be selected) is black.

Þ Model

Model is the default, updating the shaded image continuously as you move the mouse.

Þ Box

This option shows a box around the object as you move the mouse, and shades only after the moving is ended. The Box option is recommended with large models and/or slow machines.

  • Pan - Move the center point of the display with the mouse. You must press and hold the mouse button down when drawing the panning line.
  • Zoom - Zoom in or out. Press and hold the mouse button down when drawing the zooming window.
  • Twist - Changes the tilt angle of the camera.
  • Rotation -

Þ X, Y, Z

Provides continuos 360-degree rotation around an axis. It may be interrupted at any time with the right mouse button.

Þ Infinite

This command rotates the shaded model infinitely on the screen. Depending on the cursor location, the model is spun slower or faster, and in different directions. Clicking the right mouse button ends the command.

  • Clipping - There are two clipping planes that can be used to cut of the front or rear parts(s) of the model, using the following options:

Þ Move near

Þ Move far

Change the clipping planes farther or nearer the viewpoint with up and down mouse movements.

Þ Double

Þ Half

To double or halve the mutual distance between the clipping planes.

  • Save view

Þ Camera

Þ Lights

Þ All

To save the camera and/or light points into the SCENE-element.

  • Textures

Þ Blurring: On / Off

Controls whether blurring is applied to textures or not.

Þ Colors: Mix with Material / Plain Colors

Decides whether texture colors are mixed with the surface colors, or if textures are shown non-shaded in their original colors.

  • Turn two-sided On / Off - Normally all the parts of the model are shaded as two-sided, regardless of their orientation. However, it may be useful to check that all the parts of the model are consistently oriented. When two-sided shading is turned Off, the incorrectly oriented parts of the model will appear darker than the others.
  • Hide axes - To disable the drawing of the coordinate axes.
  • Save image - Stores the current image into a file.
  • Lost in space! – This command redraws the objects fitted into the window. Very useful if you get lost!
  • Done - This command closes the window.
