| Prev | 2.3 Graphics controls | Next |
The rough picture is simple: rotate with the left mouse button, translate, drag, crop, and zoom (drag along the left window margin) with the middle button, and select/pop with the right button. However these are only the defaults which can be customized.
The default shortcut keys are stored in the icm.clr file. Thefore, the mapping of keys/mouse buttons to particular graphics operations is flexible and can be easily redefined. The GUI controls and the popup menu are additional to the older shortcut keys listed here. The following shortcut keys to speed up operations in the graphics window (see the quick graphics reference guide) are defined by default. If some of these definitions are not working, check your icm.clr file in the $ICMHOME directory and modify the key/mouse-operation mapping to your liking.
Quick graphics reference guide
It is necessary to have the cursor in the graphics window. For some operations you may need to move cursor in a specified area (e.g. left margin) of the window. (Note for Windows 95/Windows NT version's users: if you use a two-button mouse hold the left button and the SPACE key instead of the middle mouse button (see picture-prompt for two-button mouse). Some controls use only a margin on the screen (e.g. Bottom5 means the bottom 5% of the graphics viewing area).
Note: if your SGI hardware stereo does not work properly you may need to install IRIX6.4 patches 2448, 2771 and 2843.
