I would like to only change material in certain parts of my imported object. I want to simulate brain activity. I am using an imported .obj and I would like to draw/change texture of the object only on the right side. Is that possible within Helixtoolkit?

I want to plot textual data into 3D plot instead of spheres or other shapes. Texts like 1,2,3 or A,B,C... or P1, P2... etc...

Hello,

I started billboard demo and i have problem. Text billboards are moving around the screen when I zooming or rotating camera. Problem occurs only when camera is in inertia mode after zooming wheel or releasing right mouse button.

I attached below recorded behaviour posted on YouTube.

I noticed that when you add billboards in xaml file everything is working fine, but i have to inserting text billboards dynamically in program.

Best regards,

Mateusz

Hello,

Thanks for great library. During several past months I was working with your library and I was able to upload different object files and corresponding textures using objreader class.

However, when I try to load any .obj from Stanford Scene Database Helix cannot show the textures.

I tried different things but yet no success. Could you please help me?

Thanks

Hi All,

I need to target .Net 3.5. When I use NuGet, it says:

What packages do I need exactly?

Thanks!

Perhaps this is a dumb question - apologies in advance. I have followed the example program to plot a 3d point cloud in Viewport3DX control. Please can someone tell me how I can update the points such that new ones appear on the screen. I don't fully understand how these are bound? Many thanks in advance.

It's easy to reproduce this, just add two tabitems with different helixviewports.

xaml code:

        <TabControl>            <TabItem Header="Tab1">
                <h:HelixViewport3D>
                    <h:BoxVisual3D x:Name="box1" Center="-3.5,0,1" Height="3" Fill="Silver"/>
                    <h:TranslateManipulator Color="Blue" Position="-3.5,0,1" Offset="0,0,1.5" Length="1" Value="{Binding Height, ElementName=box1, Converter={StaticResource Multiplier}}" Direction="0,0,1"/>
                </h:HelixViewport3D>
            </TabItem>
            <TabItem Header="Tab2">
                <h:HelixViewport3D>
                    <h:BoxVisual3D x:Name="box2" Center="-3.5,0,1" Height="3" Fill="Silver"/>
                    <h:TranslateManipulator Color="Red" Position="-3.5,0,1" Offset="0,0,1.5" Length="1" Value="{Binding Height, ElementName=box2, Converter={StaticResource Multiplier}}" Direction="0,0,1"/>
                </h:HelixViewport3D>
            </TabItem>
        </TabControl>

It works perfect in the first tabitem, but in the second tabItem I got binding error:

Cannot find source for binding with reference 'ElementName=box1'. BindingExpression:Path=Height; DataItem=null; target element is 'TranslateManipulator' (HashCode=28505784); target property is 'Value' (type 'Double')

Does anyone have a workaround or solution for this issue??

Thanks!
