Change Log

January 15th, 2002 - Version 1.2.8

• An textureViewer pedagogical example shows how to map textures with OpenGL.
• Camera::pointUnderPixel(x,y) to convert from screen to 3D coordinates.
• New cool trackball functionnalities, see mouse page for details.
• In Camera : setSceneBoundingBox(), zoomOnPixel(), viewDirection().
• The ManipulatedFrame now has a rotationSensitivity() and a translationSensitivity().

• Camera::lookAt preserves the horizon.
• Camera::fitSphere no longer modifies the orientation.
• The ManipulatedFrame bug was (finally) identified...and not fixed. See the AxisPlaneConstraint man page for details.
• There used to be a problem in the displayed FPS when the manipulatedFrame was changed (bug finder Sylvain).
• There was a Quaternion drift. They are now re-normalized (bug finder Stéphane).

• The SPECIAL mouse behavior disappears. See the mouse page.
• The select() function is removed. Overload mousePressEvent() to implement selection, see the select example.

December 14th, 2002 - Version 1.2.7-2

• QGLViewer::currentFPS() returns the current frame rate.
• QGLViewer::setSnapshotFormat() and QGLViewer::snapshotFormat().
• Quaternion::matrix() to use Quaternions as openGL 4x4 matrices.
• QGLViewer::draw3DText() to draw text in 3D, see the draw3DText example.

• Frame spinning threshold was flawed. Unwanted spinnings should no longer occur.
• Camera translation is infered from revolveAroundPoint(). Should fix problems with small objects in large scene.
• libGLcore has been removed from the rpm dependencies.

• QGLViewer::saveSnapshot() has only one parameter.

December 4th, 2002 - Version 1.2.7

• KeyFrameInterpolator class. See the keyFrames examples.
• Key Frames can be used to define a camera path. Binded on F1-12 (see shortcuts page).
• Snapshot can be saved in EPS, PS and XFIG vectorial format (thanks Cyril).
• Gestion of a QGLViewer pool. See QGLViewer::updateGLForAllViewers() and QGLViewer::connectSignalToAllViewers().
• The complete QGLViewer state can be saved and restored in XML format (see saveToFile() and restoreFromFile(). All classes implement domElement() and initFromDOMElement().
• Quaternion::inverse() and Quaternion::invert() : two separated methods (thanks Dominique).
• Frame::modified() signal is now emited when a frame is modified.
• const versions of Frame::translate() and Frame::rotate().
• Camera::setCameraFromProjectionMatrix() (thanks Sylvain).
• +/- change camera fly speed. Arrows move the camera.
• designer cw files (custom widget) are distributed with the library (in include_dir/cwFiles).
• Camera::centerScene(), binded on right mouse button double click.

• Float trigonometric function removed : now compile on Mac OS X architecture.
• QGLViewer::startScreenCoordinatesSystem() was flawed, now ok. See the screenCoordSystem example.
• The different slots (toggleDisplayFPS(), toggleDrawAxis()...) now call updateGL(). The qt bug that prevented it was patched.
• REVOLVE trackball orientation no longer depends on the mouse path.
• Vec class slightly modified (some const removed and normalize() returns a ref).
• Quaternion::axis() and Quaternion::angle() now respect the 0-pi specification.

• Most of the "Display of visual hints" functions' names were changed. See the QGLViewer documentation.
• Camera::setRevolveAroundPoint() is replaced by Camera::seamlesslySetRevolveAroundPoint().
• QGLViewer::animationPeriod() replaces QGLViewer::animationInterval().
• Camera::aspect() and QGLViewer::aspect() are now named aspectRatio().
• Quaternion::setAxisAndAngle() becomes Quaternion::setAxisAngle().
• MouseBehavior enum is uppercased : { CAMERA, FRAME, SPECIAL } (see QGLViewer::setMouseStateKey() and MouseStateKey()).
• Exit2 shortcut key ('Q') removed. Exit key (Escape) remains.

September 10th, 2002 - Version 1.2.6

• The entire library and the examples now use the threaded version of QT.
• Pressing the left and middle mouse button together rotates the scene around an axis orthogonal to the screen.
• Camera::setUpVector() function.
• Camera::setOrientation(theta, phi) : an other easy way to position the camera.
• Frame::getMatrix(), Frame::getWorldMatrix(), Frame::worldMatrix() : new matrix expressions of a frame transformation.
• FullScreen mode now set the parent window (if any) in full screen mode.
• Frame::transformOf() and similar functions to convert vectors between frames.
• In FLY mode (see Camera::setMode()), a double click changes fly speed. See mouse page.

• QGLViewer::drawLight() polished. See the drawLight example.
• Quaternion::setFromRotationMatrix fixed. Was completely flawed (thanks Sylvain).
• Camera::setOrientation fixed. It used to change the camera position too because of the complex camera frame setup (web page to come). setPosition and setOrientation can now be used in any order. See also setOrientation(theta,phi) in the NEW section.
• Frame::setConstraint() now supports a NULL pointer, which intuitively results in no constraint.
• Camera::FLY mode changed to maintain the horizon.
• Quaternion(from, to) had a problem with angles > pi/2 and null vectors.

• QGLViewer::setDisplayText() becomes QGLViewer::setEnableText (idem for QGLViewer::toggleEnableText() and QGLViewer::isTextEnabled()). It controls whether QGLViewer::drawText() actually draws text or not (default is yes). Convenient to remove all the displayed text with a single shortcut ('?' by default).
• Frame::setRotationAxisAngle(), Frame::setOrientationAxisAngle() now take angles expressed in radians instead of degrees.
• FullScreen mode shortcut key changed to Alt-Return, to fit the windows standard..
• Frame::orientationOf() is replaced by Frame::transformOf().

Mardi 21 Juillet - Version 1.2.5

• Intégration de l'affichage en stéréo.
• Apparition de startScreenCoordinatesSystem() qui permet de dessiner en coordonnées écran.
• Apparition de la fonction help(). Raccourci clavier : 'H'
• First RPM release, some cleanup, web pages updated.
• Web pages will now be in english, so that they can be shared on the web. Maintaining two versions is really too much work.

• L'affichage du texte se fait désormais en appelant drawText() directement dans draw() (plutôt qu'en dérivant la fonction displayText()).
• Key shortcut are no longer defined by static variables. They can be tuned using setShortcutKey() and setShortcutStateKey() See also setMouseStateKey, setSavePOVShortcutKey,....
