Keyboard and Mouse Controls

This is intended to be a comprehensive list of all the keyboard and mouse controls available in S2PLOT as well as a description of how they work.

General Interaction and Camera Control

KeyDescription

Middle Mouse Button (Hold)Rotate (roll) camera clockwise/anti-clockwise
f, FFocus camera on centre of geometry
h, H, HomeHome position - Returns camera to original starting position
r, RCycle rendering mode: wireframe, flat, diffuse and specular shading

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</p>Description
z, ZToggle 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...9Available 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 BarThis 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)
