New maintenance release with many improvements for metafile reader

by abenedik 20. April 2011 23:42

This release brings many improvements to almost all our products.

The metafile reader (Ab2d.ReaderWmf) library got most of the changes. The svg reader (Ab2d.ReaderSvg) also got a few new features. There were also some improvements that affected all the products except ZoomPanel. ZoomPanel control was left out of this release because the library is waiting for a major upgrade. Now when this release is out I will finally start working on it (many things are already prepared - like mini map, rotate the content, zoom slider, etc. - they just need to be polished and tested).

Let me first describe the changes that affected all the products (except ZoomPanel):

  • The licensing dialogs are now created in WPF and not in Windows Forms as before (this skips loading Windows Forms and other related assemblies and therefore speeds up the application start - especially in evaluation version).
  • Improved commercial license code that tries to find embedded resources - this code is now much faster.
  • Added splash screens to all of the converter applications.

Besides the changes above the Ab3d.Reader3ds and Ab3d.PowerToys libraries did not get any new features.

 

But as mentioned before the Ab2d.ReaderWmf library was improved quite significantly. The code that transformed positions data from metafile into WPF was rewritten from ground up. The new version now enables to specify in which units the read positions will be - they can be in Pixels, Millimeters, Inches or GdiCompatable units. This can be useful when the drawing for example in Microsoft Visio is created in millimeters, the WPF elements that are created with pasting the drawing into Paste2Xaml can be also defined in millimeters. When the default Pixel units are used, the size of the read metafile is now the same as the size that is shown when the metafile is opened by Windows.

This is the list of changes in Ab2d.ReaderWmf library:

  • Added MetafileUnits property. It specifies the units in which the metafile is read. By default its value is set to Pixel. It can be also set to Millimeter, Inch or GdiCompatable. This can be useful to preserve the positions and other properties when the drawing is created in millimeter or inch units.
  • Added AutoSize property - defines if size of the root canvas is get from metafiles bounds or its frame. When bounds is used, the root canvas size is just as big as its containing objects.
  • Added GetSize(units) method that can be used to get the size of the read metafile in the specified units.
  • The size of the read metafile is now by default (if MetafileUnits is Pixel) the same as the size shown when metafile is opened by Window.
  • Improved reading metafiles that use MM_LOMETRIC, MM_HIMETRIC, MM_LOENGLISH, MM_HIENGLISH or MM_TWIPS mapping mode.
  • When reading polyline from a metafile and it has only 2 points a Line is used instead of a Polyline.
  • Added UsedMinLineWidthFactor to get the used minimal line width.
  • Improved Ab2d.Utility.ReaderWmf.ResourceDictionaryWriter - now the process of creating ResourceDictionary from metafiles can be better customized by creating a derived class.
  • Removed obsolete Ab2d.WmfViewbox control - the control has been obsolete for a few versions - Ab2d.Controls.WmfViewbox should be used instead. This also removes the need for Designer assemblies to remove the obsolete control from Designer ToolBox.

The Paste2Xaml application that can be used to simply copy objects from drawing application and paste them into XAML was also improved - support for the new features of the Ab2d.ReaderWmd library was added.

 

Some of the changes were also made in Ab2d.ReaderSvg library:

  • Markers (arrows and other line endings) are now correctly show on line and polyline elements (before they worked only on path elements).
  • markerWidth and markerHeight attributes are now correctly handled.
  • Removed obsolete Ab2d.SvgViewbox control - the control has been obsolete for a few versions - Ab2d.Controls.SvgViewbox should be used instead. This also removes the need for Designer assemblies to remove the obsolete control from Designer ToolBox.

 

Now I have to put together the new version of ZoomPanel.

Than a new exciting area awaits - Silverlght 5 with its 3D.

Ab3d.PowerToys V1.0 released

by abenedik 21. December 2009 09:17

I am happy to announce that the final version of Ab3d.PowerToys has been released.

Ab3d.PowerToys is the ultimate helper library for work with WPF 3D.

The main parts of the library are:

  • Cameras (SceneCamera, FirstPersonCamera, ThirdPersonCamera, etc.),
  • Camera Controllers (MouseCameraController, CameraControlPanel),
  • 3D Models and Visuals (Sphere, Box, Cylinder, etc.),
  • 3D Lines,
  • Event Manager 3D (simplified event handling on 3D objects).

The created 3D objects and used 3D cameras are fully visible in Visual Studio Designer.
This means that the 3D scene can be very easily designed in Visual Studio.

With Ab3d.PowerToys programming with 3D cannot be easier!

Ab3d.PowerToys - All 3D models in Visual Studio Designer

 

The following is the list of improvements from the Release Candidate version:

  • Added public Model property as Model3D to all 3D UIElements,
  • CenterObject on ThirdPersonCamera now accepts object type instead of Model3D - so it is now possible to assign Visual3D and UIElement3D as center object,
  • Transformed the CurrentSurfaceHitPoint on MouseDrag3DEventArgs when used on Visual3D objects - now the real hit Point3D is get,
  • Fixed EventManager3D when there were no drag surface registered but there were some event sources subscribed to drag event,
  • Added HitObjectName and HitObject to BaseMouse3DEventArgs,
  • Added additional comments and code samples to help file.

 

There are also a few new samples.

Two new samples show the power of EventManager3D. One show how easy is to create a 3D object that is moved around with the mouse. The other sample shows how to use EventManager3D with Ab3d.Reader3ds library. The sample is similar to Robot Arm sample in Reader3ds samples. But instead of using sliders to move the robot, this sample utilizes the powerful EventManger3D so the robot can be moved around simply by dragging the mouse. Also the light can be switched on and off by clicking on it.

The most interesting new sample is the 3D Cannon simulation. It shows a 3D simulation of a cannon where user can set many parameters like Gravity, Drag factor, ball mass, etc. It is also possible to switch between many possible cameras. The following image shows the sample in action:

Ab3d.PowerToys - Cannon simulation

 

The 60-days evaluation of Ab3d.PowerToys can be downloaded from Downloads page.

The price for Ab3d.PowerToys license starts from $179.00 (very low price for the amount of work-hours saved). It is also possible to buy full source code for the library.

And that is not all. When a Ab3d.Reader3ds Pro license is bought, the Ab3d.PowerToys license is get for free!

And that is still not all - see the next blog post that is coming very soon Smile

Ab3d.PowerToys

Ab3d.PowerToys library advanced to Release Candidate

by abenedik 20. November 2009 22:16

Ab3d.PowerToys

The Ab3d.PowerToys library has advanced to Release Candidate version.

Here is the list of changes from beta 2:

LIBRARY:
- Added Ab3d.UIElements namespace with 3D objetcs that derive from UIElement3D
- Added ToolTip property to all classes under Ab3d.UIElements namespace
- Added PreviewCameraChanged event to BaseCamera - with the event it is possible to limit the camera movement with setting the Handled property in the event args to true
- Added ShowRotateCursorOnMouseOver property to MouseCameraController - if true it shows the RotationCursor when UsedMouseButton is set to Left and mouse is over the EventsSourceElement
- Added MaterialTypeConverter so it is possible to set Material and BackMaterial on all Ab3d Visuals and UIElements with simply specifying the color name
- Added constructor for Box3DModel that takes Rect3D as parameter
- Improved possibility to set custom images to CameraControlPanel - also added sample to show this
- Redesigned the TargetPositionCamera and TargetRect3DCamera classes - added BaseTargetPositionCamera and BaseTargetRect3DCamera
  This way it was possible to add additional methods to TargetPositionCamera - MoveLeft, MoveUp, etc that move and strafe the camera
  Also now the SceneCamera and other cameras that are derived from TargetRect3DCamera do not have TargetPosition and TragetRect3D properties
- Improved Design Time support:
  Removed all unused properties in VS Properties Editor for cameras
  Added icons for ToolBox (not final yet)
- Changed IsEnabled property in LinesUdater into UpdateMode enum - open for future improvements
- Added IsEmissiveMaterialUsed to LinesUdater to control if EmissiveMaterial is used to create the lines
- Added tons of comments into the code - also improves the help file

SAMPLES:

- Added samples for Ab3d.UIElements
- Added UIElementsToolTipSample - how simple is to use ToolTip property on Ab3d.UIElements
- Added CustomControlPanelSample - demonstrates how to use custom images for CameraControlPanel
- Added simple camera animation sample
- Added sample to demonstrate how to limit the camera movement with using PreviewCameraChanged event
- Improved LinesStressTest sample to show how to manually update the lines to improve the performance of the application

OTHER:

- Added ClassDiagram images to Resources directory so the class diagrams can be printed by the users

 

The Release Candidate version can be downloaded from my https://www.ab4d.com/Downloads.aspx

If you already have a previous version installed, just install the new version over the previous one (no need to uninstall the previous version first).

 

Note: This version will expire on on 31th January 2010.

Release is planned for the first half of December 2009.

Ab3d.PowerToys

Ab3d.PowerToys Beta 2 available

by abenedik 4. November 2009 00:23

The new version of Ab3d.PowerToys brings you even more useful classes and utilities for WPF 3D.

The sample application that comes with the library is again a very good demonstration of capabilities of the WPF 3D engine.

 

The main new part of the library is added support for creation of basic 3D objects and 3D lines.

Now the library contains all the essential parts that are needed with 3D WPF development:

  • advanced cameras
  • camera controllers
  • simplified mouse events handling on 3D objects (improved in beta 2)
  • basic 3D models (new in beta 2)
  • 3D lines (new in beta 2).

 

The following basic 3D objects can be created: Plane, Circle, Box, Pyramid, Sphere, Cone and Cylinder.

Advantages of the 3D models in Ab3d.PowerToys are:

  • The biggest list of supported 3D objects with lots of propertes for customization of objects.
  • Many different ways to create 3D objects: in XAML with Visual3D classes, in code with Model3DFactory class (to create GeometryModel3D objects) or in code with classes under Ab3d.Meshes namespace to create MeshGeometry3D objects.
  • Highly optimized code to make the creation as fast as possible.

Ab3d.PowerToys Samples - All 3D models

Ab3d.PowerToys Samples - All 3D models

 

3D lines can be created from code with Ab3d.Models.Line3DFactory. The methods in the Line3DFactory return 3D lines as GeometryModel3D objects. This means that you can add 3D lines to the existing Model3DGroup.

The lines can be also created as Visual3D objects with the following classes: LineVisual3D, MultiLineVisual3D, PolyLineVisual3D, AxisVisual3D, ColoredAxisVisual3D or WireGridVisual3D. The visuals can be used in XAML which means that you can see the results in Visual Studio designer.

There is also a Ab3d.Models.WireframeFactory to create wireframe objects from existing 3D models. WireframeFactory also contains methods to create lines for 3D model normals.

Because WPF does not natively support 3D Line, the line must be created with 3D model that consists of two triangles. The positions of the triangles depend on the position of the camera and size of Viewport3D. This means the code that draws the line must constantly check if the camera was changed, the parent Viewport3D or Visual3D is changed or the parent is not visible any more. This process can normally affect performance. The implementation in Ab3d.PowerToys library is designed in such a way that the performance impact is minimal. The code caches many properties and updates only those lines that need update. When the update is needed the new MeshGeometry3D is not rebuild from stretch but instead only positions are changed. It also checks if the lines were removed from the visual and acts accordingly. There are a few 3D lines implementation for WPF, but the highly optimized lines updater makes this implementation the most advanced.

Ab3d.PowerToys Samples - All 3D models

 

Important:

The Ab3d.PowerToys will be available as a standalone product.

It will also be available for free with Ab3d.Reader3ds Pro version (existing customers of Ab3d.Reader3ds Pro will also get the license).

 

Beta notice:

The current version of Ab3d.PowerToys is in Beta 2. That means that it is almost feature complete but is not yet fully tested and documented. This version will expire on 31th January 2010.

Roadmap:

  • Beta 2 - start of November 2009
  • Release Candidate - middle of November 2009
  • Release - start of December 2009

Ab3d.PowerToys

Ab3d.PowerToys beta 1 introduced

by abenedik 13. October 2009 23:13

The Ab3d.PowerToys library is a collection of classes and utilities that simplify programming with 3D in WPF. With Ab3d.PowerToys programming with 3D was never easier!

The following are the main parts of the library:

  • Cameras
  • Camera Controllers
  • Mouse Event Manager 3D

Ab3d.PowerToys Samples - Wind Generator sample

The library defines a few new Cameras that can be used instead of the current WPF's cameras. The main difference between Ab3d Cameras and WPF cameras is that Ab3d Cameras does not use Vectors to define the LookDirection, but instead use angles in degrees to define it. This is much more natural. For example if you want to look at the scene a little bit from the right and from above, you just define the Heading to be 30 and Attitude to be -45. You can also define the Distance from the scene. The most important Ab3d Cameras are: SceneCamera, FirstPersonCamera and ThirdPersonCamera. All the Ab3d Cameras with their properties can be seen on the class diagram.

Camera Controllers are used to control the camera. The MouseCameraController can be used to change the angle and distance of the camera with the mouse. This way it is very simple to rotate the camera around. The CameraControlPanel shows nice buttons to rotate the camera and move the camera closer or farther away. There is also a CameraPreviewPanel that graphically shows at which angle the camera is looking at the object or scene.

The following code demonstarates that with only a few lines of xaml a WPF application can use a camera that is showing the whole scene (SceneCamera) and can be rotated by the mouse (MouseCameraController) or by nice buttons (CameraControlPanel). There is also a preview of the camera that is showing from which angle the camera is looking at the scene. Also if the WindGeneratorModel model does not contain a light, a camera light is automatically added to the scene and it is iluminating the scene from the camera's position (ShowCameraLight="Auto").

                                 HorizontalAlignment="Right"/>
  </Grid>
</Window>

 

The EventManager3D class is a helper class that enables user to simply subscribe to mouse events on 3D objects. The following mouse events are supported: MouseEnter, MouseLeave, MouseDown, MouseUp, MouseClick, BeginMouseDrag, MouseDrag, EndMouseDrag (MouseDoubleClick is not in available in beta). This way you do not need to do the complicated 3D hit testing any more. You can simply subscribe to mouse events. This way you the code is much simpler and better organized.

The following code shows a sample used of EventManager3D:

                    
EventSource3D eventSource;
EventManager3D eventManager;

eventManager = new EventManager3D(MainViewport);                                 


eventSource = new EventSource3D();
eventSource.TargetObject = myButton3D;
eventSource.MouseClick += new MouseButton3DEventHandler(myButton3D_MouseClick);

eventManager.RegisterEventSource3D(eventSource);                                 


eventSource = new EventSource3D();
eventSource.TargetObject = myMovableObject3D;
eventSource.BeginMouseDrag += new Mouse3DEventHandler(myMovableObject3D_BeginMouseDrag);
eventSource.MouseDrag += new MouseDrag3DEventHandler(myMovableObject3D_MouseDrag);
eventSource.EndMouseDrag += new Mouse3DEventHandler(myMovableObject3D_EndMouseDrag);

eventManager.RegisterEventSource3D(eventSource);                    

 

Beta notice:

The current version of Ab3d.PowerToys is in beta. That means that it is not yet features complete and not fully tested.

Roadmap:

  • Beta 1 - 13th October 2009
  • Beta 2 - end of October 2009
  • Release Candidate - middle of November 2009
  • Release - start of December 2009
