example, that is referenced by the <img src="images/sphere.png" width="14" height="14" alt="sphere"/> <h2>Main features</h2> <ul> <li>A camera trackball to easily move the camera in the scene (explorer or walkthrough mode) <a href="examples/simpleViewer.html"> <img src="images/sphere.png" width="14"height="14" alt="simpleViewer example"/></a> <a href="examples/callback.html"> <img src="images/sphere.png" width="14" height="14" alt="callback example"/></a></li> <li>Definition of a intuitive world coordinates system (the OpenGL modelView matrix made easy) <a href="examples/simpleViewer.html"> <img src="images/sphere.png" width="14" height="14" alt="simpleViewer example"/></a></li> <li>Coordinate systems (and hence objects) can easily be moved with the mouse <a href="examples/manipulatedFrame.html"> <img src="images/sphere.png" width="14" height="14" alt="manipulatedFrame example"/></a> <a href="examples/luxo.html"> <img src="images/sphere.png" width="14" height="14" alt="luxo example"/></a></li> <li>Hierarchical coordinate systems (frames), with functions to convert from a frame to any other <a href="examples/luxo.html"> <img src="images/sphere.png" width="14" height="14" alt="luxo example"/></a> <a href="examples/frameTransform.html"> <img src="images/sphere.png" width="14" height="14" alt="frameTransform example"/></a></li> <li>KeyFrameInterpolator to animate those frames, and especially the camera <a href="examples/keyFrames.html"> <img src="images/sphere.png" width="14" height="14" alt="keyFrames example"/></a> <a href="examples/simpleViewer.html"> <img src="images/sphere.png" width="14" height="14" alt="simpleViewer example"/></a></li> <li>Simple object selection using mouse <a href="examples/select.html"> <img src="images/sphere.png" width="14" height="14" alt="select example"/></a> <a href="examples/multiSelect.html"> <img src="images/sphere.png" width="14" height="14" alt="multiSelect example"/></a></li> <li>Screenshot saving in different file formats (jpg, png, bmp...), including vectorial rendering (eps, ps, xfig) <a href="examples/simpleViewer.html"> <img src="images/sphere.png" width="14" height="14" alt="simpleViewer example"/></a></li> <li>Complete and entirely customizable <a href="keyboard.html">keyboard shortcuts</a> and <a href="mouse.html">mouse</a> behavior <a href="examples/keyboardAndMouse.html"> <img src="images/sphere.png" width="14" height="14" alt="keyboardAndMouse example"/></a></li> </ul> <h2>and also...</h2> <ul> <li>Many simple <a href="examples/index.html">examples</a> illustrating the different functions <a href="examples/index.html"> <img src="images/sphere.png" width="14" height="14" alt="List of examples"/></a></li> <li>A complete reference <a href="refManual/hierarchy.html">documentation</a> <a href="refManual/hierarchy.html"> <img src="images/sphere.png" width="14" height="14" alt="Reference documentation"/></a></li> <li>Display of the frame rate, of a world axis, of a 2D grid and of camera paths, full screen display... <a href="examples/simpleViewer.html"> <img src="images/sphere.png" width="14" height="14" alt="simpleViewer example"/></a></li> <li>Easy drawing of text directly in screen coordinate system (2D overlay) or in 3D <a href="examples/screenCoordSystem.html"> <img src="images/sphere.png" width="14" height="14" alt="screenCoordSystem example"/></a></li> <li>Extendable displacement constraints that can be applied on frames <a href="examples/constrainedFrame.html"> <img src="images/sphere.png" width="14" height="14" alt="constrainedFrame example"/></a> <a href="examples/constrainedCamera.html"> <img src="images/sphere.png" width="14" height="14" alt="constrainedCamera example"/></a></li> <li>Viewer state is saved and can be restored at each application start <a href="examples/simpleViewer.html"> <img src="images/sphere.png" width="14"height="14" alt="simpleViewer example"/></a></li> <li>A simplified drawing function can be provided to guarantee interactivity, even with large scenes <a href="examples/fastDraw.html"> <img src="images/sphere.png" width="14" height="14" alt="fastDraw example"/></a></li> <li>The possibility to mix 3D and 2D (with intuitive pixel coordinates) drawing <a href="examples/screenCoordSystem.html"> <img src="images/sphere.png" width="14" height="14" alt="screenCoordSystem example"/></a></li> <li>Possible animation of the scene at a given frame rate <a href="examples/animation.html"> <img src="images/sphere.png" width="14" height="14" alt="animation example"/></a></li> <li>Stereo display (provided that your hardware supports it) <a href="examples/stereoViewer.html"> <img src="images/sphere.png" width="14" height="14" alt="stereoViewer example"/></a></li> <li>Robust implementation of the basic <code>Vec, Quaternion</code> and <code>Frame</code> classes <a href="examples/frameTransform.html"> <img src="images/sphere.png" width="14" height="14" alt="frameTransform example"/></a></li> <li>Copy buffer to texture function</li> <li>Customizable help window <a href="examples/keyboardAndMouse.html"> <img src="images/sphere.png" width="14" height="14" alt="keyboardAndMouse example"/></a></li> </ul> <h2>Philosophy</h2> Classical 3D viewer features are directly available, so that you can quickly start the development of a new application, focussing on <i>what</i> is drawn instead of <i>how</i> to make the computer draw it. <p> All these functions are very easy to use in your application code. Adding code to select scene objects and then manipulate them using the mouse can be done in 5 minutes. </p> See the different <a href="examples/index.html">examples</a> to get an more precise idea. <a href="mailto:contact@libqglviewer.com">Send an email</a> if you think of a new feature. <p> <a href="http://validator.w3.org/check/referer"><img src="images/xhtml.png" alt="Valid XHTML 1.0!" height="31" width="88"/></a> <a href="http://jigsaw.w3.org/css-validator/check/referer"><img src="images/css.gif" alt="Valid CSS!" width="88" height="31"/></a> <i>Last modified on Monday, December 06, 2010.</i> </p> </body></html>
