Does anyone know how to add "X", "Y", "Z" text on the coordinate system, without modifying source code?

To do this without modifying the source code of Helix3D, you would have to reconstitute the <style> of the HelixViewport3D. You can find the original style in the Generic.xaml file in the codebase for a template.

 

Copy and place it in any resource dictionary, and then modify the "PART_CoordinateView" portion to read:

                            <Viewport3D x:Name="PART_CoordinateView" 
                                        Width="{TemplateBinding CoordinateSystemWidth}" Height="{TemplateBinding CoordinateSystemHeight}" Margin="0" 
                                        HorizontalAlignment="{TemplateBinding CoordinateSystemHorizontalPosition}" VerticalAlignment="{TemplateBinding CoordinateSystemVerticalPosition}" 
                                        ClipToBounds="False" Visibility="{TemplateBinding ShowCoordinateSystem, Converter={StaticResource BoolToVisibilityConverter}}">
                                <local:ArrowVisual3D Point2="8 0 0" Fill="#964B4B" />
                                <local:TextBillboardVisual3D  Position="9 -2 1" Text="X" Height="10" />
                                <local:ArrowVisual3D Point2="0 8 0" Fill="#4B964B" />
                                <local:TextBillboardVisual3D Position="-2 9 1" Text="Y" Height="10" />
                                <local:ArrowVisual3D Point2="0 0 8" Fill="#4B4B96" />
                                <local:TextBillboardVisual3D Position="-2 -1 9" Text="Z" Height="10" />
                            </Viewport3D>
Then, wherever you set the HelixViewport3D up, just set its Style property to your custom style.

Rob,

Thanks for the reply.

I placed the style in my Resource Dictionary, but I get the error:

"Could not register named object. Names not supported under ResurceDictionary scope."

When I remove the x:Name="PART_CoordinateView", the previous error goes away, but I get this error:

"Failed to creat a 'DependencyProperty' from the text 'CoordinateSystemWidth'."

I can't see your code, but, you need the entire style from the Default.xml for HelixViewport3D; I only posted the part that needs changing.

The PART_CoordinateView x:Name must stay attached to this Viewport3D snippet within the style.

That was dumb of me. Thanks for the help.

Are you able to help with another problem?

I draw piping systems based on an observable collection, then setting ViewPort3D ItemsSource to this collection. This works fine, however when I first load the application, it fires an event on my treeview, which loads a "case", which loads the collection of pipe. But the pipe system does not appear. I have had to add a button to "redraw" the pipe system.

I tested yesteray and determine that if I create a meshbuilder, with the .AddPipe method per objo's suggestion (Jun 25, 2012 1:33), it works as expected.

However, I need to create one PipeVisual3D at a time in order to color the object with a gradient (it is colored based on temperature, pressure, etc.

Also, I need elbows to join pipe. In the works?, or any suggestions?

Thanks for any help or ideas?

Two PipeVisual3D's and a sphere, scaled to the sizes you need, should resemble a pipe elbow. You'd need to write the class that emits it and scale the results.

I'm working on similar graphics problems but I don't have employer permission to release code.

You could also use texture coordinates, correlated with triangle vertices, and combined with a GradientBrush to plot color data along your surface. A pipe geometry is a relatively simple thing to tessellate. It wouldn't be hard to further tessellate so that you get vertices at points along the pipe that align with your data results.

I added the coordinate system labels to the default template. I hope it is ok for everyone...

Thanks for sharing the code, Rob!
