dynamically add the more MultiMaterialBoxVisual3D and Achieve mouse event

Wed, 02 May 2012 10:22:14 +0200

I dynamically add the more MultiMaterialBoxVisual3D how to achieve a mouse click event, how I points which MultiMaterialBoxVisual3D current click

my code is :

for ( int k = 1; k <= FIBER_disk_number; ++k)
{
Ab3d.Utilities.VisualEventSource3D visualEventSource;
_eventManager = new Ab3d.Utilities.EventManager3D(MainViewport);
my3d_collection = (Visual3DCollection)MainViewport.Children;

L += 15;
MultiMaterialBoxVisual3D My_3D_materialbox_box = new MultiMaterialBoxVisual3D();
Material new_left_material, new_front_material;
new_left_material = new DiffuseMaterial(Brushes.LightBlue);

ImageBrush berriesBrush = new ImageBrush();

berriesBrush.ImageSource = new BitmapImage(
new Uri("pack://application:,,,/Dnf_Data_lib;Component/My3D_station/ddf_slot.png", UriKind.Absolute)
);
new_front_material = new DiffuseMaterial(berriesBrush);

My_3D_materialbox_box.FrontMaterial = new_front_material;

How to measure size of content once scaled to fit the zoombox?

Fri, 09 Mar 2012 18:38:03 +0100

I have been looking through the properties and methods you have available, but I am not sure there is one that gives me a way to measure my content once its scaled to fit. I was trying ActualContentBounds but its results are a little confusing. For example I have content that is 5423x2822 unscaled. ActualContentBounds is returning 1625x1149 which is not proportional to the starting size. If there is no way to get the scaled size, is there a way to get the to scale factor used to size the content down to fit the zoom panel? I could at least use that to calculate it.

Zoom to left upper corner instead of center

Fri, 24 Feb 2012 07:18:17 +0100

Hi Andrej,

just starting out with ZoomPanel, sorry for the newbie-ness ...

When zooming in with the mouse wheel the zoom is centered, i.e. the panel content (unsurprisingly) gets bigger and at the same time moves in the direction of the upper left corner, until it may no longer be visible.

I'd rather have the upper left corner as the "anchor point" when zooming, rather than the center position. How would I do this? I have been playing with SetZoom but somehow I am not getting this right.

Thanks for your help

Line Thickness

Thu, 23 Feb 2012 13:46:27 +0100

There seems to be a difference of scale when setting line thicknesses?

I'm creating a polyline and a line3d (see attached):

Line3DFactory.CreatePolyLine3D (yellow)
Line3DFactory.CreateLine3D (red)

but to get the line thicknesses to look the same, the poly line has 0.4 and the line3d 12 set as thicknesses.

Why is this?

Whats the proper way to reload a svgviewbox control?

Mon, 20 Feb 2012 22:14:57 +0100

I have a scenario where I am wrapping a zoompanel around a svgviewbox that I need to load/reload many times. Currently I am simply setting the Source property to a new svg file, but after a couple times, I start getting out of memory errors. Is this the correct way to change the source, or is it not designed to do this?

ReaderWmf leaks temporary files

Tue, 14 Feb 2012 16:32:44 +0100

I have the following code:

Code:

using (ReaderWmf reader = new ReaderWmf())

{

    Image image = reader.ReadGeometry(metaFile, geometrySettings);

    // ...

}

Every time this section is executed, a EMF file is created in %LOCALAPPDATA%.
There is a first chance exception on the closing brace (i.e. the Dispose call) "The process cannot access the file 'C:\Users\kg\AppData\Local\9333da9f-ef9d-4fd1-ab8a-66d8b0647bc0.emf' because it is being used by another process." Here is the call stack:

Code:

    mscorlib.dll!System.IO.__Error.WinIOError(int errorCode = 0x80070020, string maybeFullPath = "C:\\Users\\kg\\AppData\\Local\\9333da9f-ef9d-4fd1-ab8a-66d8b0647bc0.emf") + 0x321 Bytes    

     mscorlib.dll!System.IO.File.Delete(string path) + 0x99 Bytes    

     Ab2d.ReaderWmf.dll!Ab2d.ReaderWmf.ر() + 0x6c Bytes    

     Ab2d.ReaderWmf.dll!Ab2d.ReaderWmf.Dispose(bool disposing = true) + 0x2b Bytes    

     Ab2d.ReaderWmf.dll!Ab2d.ReaderWmf.Dispose() + 0x22 Bytes

Using Sysinternals ProcessExplorer I found that there is no other process having an open handle to the file (only my program itself).

Klaus

Edit: Maybe this is the same problem as in the post "Problem with ReaderWmf Class in Web Service (WCF)". The metaFile variable in my code snippet is indeed a Stream.

Does your library also supports touch events instead of mouseevents?

3ds File and uiElements?

Tue, 24 Jan 2012 16:36:05 +0100

Hi,

I have a Viewport3D with a couple of ConeUIElement3D's in it, and I can drag the view around quite happily.

I'd like to load a .3ds model into this Viewport to display alongside my elements and still be able to drag the view around - clicking on the cones or on the 3ds model - is this even possible?

thanks in advance

ConeUIElement3D Point Set

Tue, 24 Jan 2012 16:32:21 +0100

Hi,

Does anyone know if there is a set of Points I can have access to if I have a ConeUIElement3D with say, 10 Segments? I have the BottomCenterPosition and radius etc but wondered if there's a way to get, for instance, the corner points of each segment etc, a lower-level description of the cone?

thanks in advance

Please let me know what's going on?

I'm using VS2010 on Windows 7 with UAC turned off running in Administrator mode on a home computer.

Looks like you guys are very pedantic about license security to the point where legitimate users can't even use it!

Just tried this on another box running Win 7 but with VS2010 Express and everything in the trial version worked.

Does your software support VS2010 Ultimate? There arent really that many other differences between the computers.

WPF controls stop working when .3ds is loaded

Mon, 05 Dec 2011 13:02:07 +0100

Good morning. I'm trying to integrate .3ds models into my application to make the 3D development faster, since converting to XAML (our actual approach) has a lot of issues. The model loading works fine, but every control on the screen - buttons, sliders, comboboxes etc - stops working immediately. Is this supposed to happen, should I be loading the model in a different window or page?
I'm using Ab3d.Reader3ds.ReadFile to load the model into a viewport3D. The samples have a differente way of building menus, but I'm in a trial-an-error effort for several days and I don't have much time left for radically differente methods, any advice would be very helpful.

Thanks in advance.

Lights sources and animation

Tue, 22 Nov 2011 23:07:52 +0100

Hello,

I'm using Reader3ds with PowerTools for 3D scene visualization and animation and I have found one issue with lights.

My 3D scene contains 5 light sources with color #FF666666. This scene looks fine, lighting is soft and beautiful, but when I run the animation, all lights change color to #FFFFFFFF that breaks scene lighting.
Same behavior in the Viewer3ds.

Sample image attached.

Are there any workaround for this issue?

Thanks,
Vladimir

How do you reset the viewbox to fit content when a rotation is applied?

Wed, 16 Nov 2011 21:00:34 +0100

When I apply a rotation to the zoompanel, is there a way to reset the viewbox so that its base size is the size of the content once its rotated?

For example I have content which is rectangular and I rotate it 90 degrees clockwise so its in a landscape (wider than tall) orientation. When it zooms all the way out its fits to the size of the content unrotated when its portrait (taller than wide) orientation. Is there a way to tell it what the correct size is?

As a workaround I simply figured out the minimum zoom scale and start it off at that size but I am sure there has to be a more elegant way.

SetZoom does not work when already zoomed in or panned

Mon, 14 Nov 2011 22:01:58 +0100

I am using code from the example you created for panning and zooming to a specific object which works fine when you are zoomed all the way out. Once you are zoomed in or panned at all, the method does not do anything. I tested to make sure it wasn't the values I was giving it, which were the same whether it was zoomed in or not. I haven't been able to test using the example you posted because I get errors when trying to run it.

Zoom and pan to specific object

Tue, 08 Nov 2011 12:57:27 +0100

In the thread "How to reset without losing rotation?" (http://forum.wpf-graphics.com/showthread.php?tid=196) user asked a question on how to zoom and pan to a specific object.

Because this could be very interesting for others I have created a separate thread so the solution will be better visible.

The following code is used to create random objects inside ZoomPanel and then the user can select the objects from the ListBox and the ZoomPanel will zoom and pan to the object.

Cant capture MouseUp of left button on childen of zoom panel

Fri, 04 Nov 2011 20:46:58 +0100

No matter how I declare the handler for the MouseUp event on children within the zoompanel, the event never fires. It does on right mouse button and if I remove the zoompanel from around it. I even went as far as attaching to the event manually using AddHandler and using the "handledEventsToo" option. Any thoughts on why this is happenning?

To elaborate just a bit more, I have a zoompanel with a canvas inside it. The canvas is loaded with content dynamically at runtime that want to capture all mouseup events from every child. The canvas itself is not being clicked. When I add the handler to the canvas, it never fires. The content within the canvas should be firing the event, and they do when they are not within the zoompanel. They bubble up to the canvas as they should in that case. What is the zoompanel doing that would prevent this from working?

public Viewbox Read(Stream stream)

I get the following exception (UnauthorizedAccessException):

Access to the path 'c:\windows\system32\inetsrv\be156149-e1c8-4327-a8c5-ef809e05fbad.emf' is denied.

I tried to give the user permissions IIUSR_USERS in this folder, but is not allowed.

As I can do?

Regards.
