Function Keys and Saving Images or Geometry
| Key | Description |
|---|---|
| F1 | Toggle help information - displays a list of keyboard options |
| F2 | Toggle bounding box |
| F5 | Write geometry and camera view file to disk |
| F6 | Write geometry, camera view file and current screen image to disk |
| F7 | Toggle recording of geometry, camera view file and image |
| F9 | Write large (3 x 3) image to disk - saves a series of 'chopped up' images for recombining to make a high quality image |
| F10 | Write current screen image to disk, saved in the current working directory |
| F11 | Create QTVR object images - rotates the scene creating a series of images (e.g. each frame can be joined to make a movie) |
| F12 | Toggle image recording - same as F11 but allows the user to rotate the geometry themselves |
| c | Append current camera position to camera.path file |
| d | Toggle debug mode - provides information on camera position, frame rates, etc. |
Notes:
- Saved images are in TGA format and are numbered sequentially and uniquely
- On Apple OSX platforms, it is usually necesary to hold down the fn key while using the above keystrokes
Callback System
| Key | Description |
|---|---|
| z, Z | Toggle drawing of dynamic geometry by
disabling/enabling a callback function set with the S2PLOT command <a href="reference.php?e=cs2scb&s=11">cs2scb</a> |
| 0...9 | Available for assigning to callback functions using
S2PLOT function <a href="reference.php?e=cs2sncb&s=11">cs2sncb</a>. The default operation of keys 1...7 is to display standard camera views. 0, 8 and 9 have no default behaviour |
| Space Bar | This key press is available through the callback
system for programmer-assigned tasks. The number of times the space bar key is pressed is passed to a callback function as a parameter. For an example, see the sample programs s2uc7.c (C) or fs2uc7*.f (FORTRAN) |
Handles
| Key | Description |
|---|---|
| shift-s | Toggle drawing of handles for selection |
| shift-C | Toggle drawing of cross-hairs |
