New features:

1. Calques 3D is now developed using Microsoft Visual C++ 2008.
2. Added support for a new 3D-mouse device, the SpaceNavigator. See the instructions about usage and configuration.
3. Added a German version of the interface (thanks to Alfred Flaßhaar).
4. Changed the way multiple languages are supported. The various translations of the interface are now available as separate DLLs, in conjunction with a stand-alone executable containing the default English interface.
   Note that only one translated DLL will be installed on your computer, depending on which language you chose at installation. Although possible, Calques 3D does not allow a change of language at run-time (to avoid a clash with the interface layout saved in registry by the BCGControl library).

Fixes:

1. Fixed bug in the display of Z-aligned lines in the OpenGL view.
2. Changed the navigation interface of the option dialog box to a tree-like widget.
3. Switched to latest version of the MFC Grid Control (v2.26) external library.
4. Cleaned and improved internal data structure (for easier migration to proper open-source code in the future).

New features:

1. A first draft of the conic section object has been added in Calques 3D.
   You can construct it as the intersection of a cone and a plane (from the menu Construction | Intersection).

Fixes:

1. Changed the behaviour of the user-defined points of view list: the default PoV can now be removed, changed or renamed.
   Note that if all points of view are removed from the list, a default one will be automatically created.
2. Fixed a bug with the selection of the initial/default point of view in the Universe view.
3. Fixed a bug in the selection of cylinders and cones.
4. Several export predicates (Maple and Mathematica) have been fixed or added: common perpendicular line, circle and arc of circle, intersection cone/line, cylinder, polygon,
5. Several missing icons have been added (for objects and constructions).

New features:

1. Introduction of user-defined point of views in the Universe view.
   By using the define... command (either in the Visualisation | Point of View menu or in the menu-icon in the toolbar of the view), you can save the current orientation of the observer's point of view for future usage. Using the command open a list box where you can save the current point of view, removed previous ones and reorganised them.
   The menu will hold up to 4 points of view, on top of the default one (which cannot be modified or removed). These points of view are saved with the construction.
2. A new command (Visualisation | Show Hidden) enables the display or not of all hidden objects in the Universe. Hidden objects are drawn in simple shape and with a different color, as long as the command is switched on.
   Note that the color used for hidden objects is hard-coded but will be avaiable for modification in the preferences soon.
3. The cone has been added as a new object. The object is a right-handed cone with a circular basis. Its construction relies on three points: its apex, a second point defining its axis (and its direction vector and, therefore, its primary nappe) and a third point defining its envelope (and its opening angle).
   Note that the current version is still limited in the detection of hidden part and will be fixed a soon as possible.
4. The appearance pane of the preference dialog has been updated to provide access to configuration elements of the cone: its default color, whether it has to be treated (and displayed) as a double cone or not and the number of edges displayed on its envelope.
5. New construction methods, based on the cone, have been added: intersection cone/line and point on cone.
   Note that in the current version, a limitation of the computational algorithms means that both methods are valid only with the primary nappe.
6. The History view now allows to temporarily display hidden objects while they are selected. An option in the new History pane of the preference dialog enables or disables this functionality.
7. The display of locus has been improved by introducing a proper (triangular) mesh structure. It allows a better detection of the orientation and surface of the mesh elements. Note that the locus computation has still problem in dealing with discontinuity (see the hyperboloid for example).

Fixes:

1. A bug in the detection of the hidden parts of the cylinder has been fixed.
2. The visual feedbacks during the construction of objects has been improved. Some are still missing...
3. Fixed a bug with the computation of the locus, causing infinite loop at the opening of a saved document.
4. The description of spheres (i.e. differentiating between a sphere defined by a radius or by a point on its envelope) has been fixed.
5. The text associated with the designation of cylinders in construction tasks (e.g. point on cylinder, intersection cylinder/plane) has been fixed.
6. The description of several errors (properties not met for the definition of objects) has been improved.
7. Various icons for the object and construction commands have been added to the interface (menus and toolbars).
8. Loading and saving preferences (from/to registry) has been updated.
9. The preference dialog has been improved (title fixed, improved loading, missing appearance options added, etc.)
10. A bug in the orientation of lines in the OpenGL view (notably with segments and rays) has been fixed.
11. The color of objects is now properly propagated in the OpenGL view (except for points that remains red and spherical).
12. The symbolic export of spheres defined by their radius has been fixed.
13. A bug in filling the list of variables in the context menu of the MathPad view has been fixed.

Fixes:

1. A bug with the construction of spheres, preventing the selection of dependent points for its parents, has been fixed.

Go the download page http://www.calques3d.org/download.html

New features:

1. The construction of spheres has been improved by allowing the definition of a sphere given its center and its radius (specified by an existing segment line). The construction command and the designation mechanism have been updated to reflect this new possibility.

Fixes:

1. A few bugs in the activation and management of the Verify dialog have been fixed.
2. A bug in the serialisation of objects, preventing their versioning, has been fixed.
3. Warning and information icons have been added to the alert indicator in the task bar.

Go the download page http://www.calques3d.org/download.html.

New features:

1. An alert mechanism has been introduced in Calques 3D, in order to attract the attention of the user on issues that are not vital and therefore that don't need to interrupt the use of the system. The task bar contains a special indicator that displays a short text (and a tooltip) highlighting the issue. A double-click on the message will activate a more detailed description of the issue.
   The current shape of the alert indicator is still crude and will be improved shortly.
2. This alert mechanism is now used to indicate the existence of objects in the MathPad view, when the user opens an existing document. The indicator on the task bar will contain a "MathPad" tag; by double-clicking on it, a dialog box indicates the existence of objects in the MathPad view and asks the user whether the view should now be opened or not. A check box in the dialog also allows Calques 3D to remember the choice and not prompt the user for the same question in the future.
   The choice of asking or not the question can be specified in the MathPad tab of the Options dialog.

Fixes:

1. A bug in the symbolic export of the intersection of two lines has been fixed.
2. A bug in the color definition of planes/polygons in the OpenGL view has been fixed.
3. The background color for the OpenGL view has been changed.
4. A bug with the display of the surface of polygons has been fixed (or kind of). When the floor or the walls are activated as a system of reference, the surface of polygons is not displayed, their edges are used instead. Surfaces are only displayed when the axes or no system of reference are chosen.
   This behavior can be changed by checking/unchecking the relevant option in the Universe tab of the Options dialog, forcing surfaces to be displayed at all time.
   Note that the problem of properly rendering the hidden parts of polygons (hidden either by other polygons or by the system of reference itself) has still not be fixed and that visual inconsistence are unavoidable.
