How to make object invisible for mouse

maxxer 1 year ago in Question 0

Hello,


I have many objects loaded in a scene (part of a SortingVisual3D) and added a manipulator to each of them. Everything works perfectly.


Now I want to surround them by a transparent cylinder. Also this works.


The problem I have now is that the manipulators are not useable when the objects are in the transparent cylinder because the mouse is captured by the cylinder.


Is there a way to make the box invisible for mouse operations?


I am using Helixtoolkit for C# WPF

Unable to run WPF.SharpDX demos

Van 1 year ago in Question • updated 1 year ago 1

I am trying to evaluate helixtoolkit for use in an existing WPF application. I cloned the repo and compiled everything, but when I try to execute any of the WPF.SharpDX examples I get an error message in the application:


System.InvalidOperationException: Cannot call this method without a back buffer.
   at System.Windows.Interop.D3DImage.AddDirtyRect(Int32Rect dirtyRect)
   at HelixToolkit.Wpf.SharpDX.DPFCanvas.UpdateAndRender() in C:\helix-toolkit\Source\HelixToolkit.Wpf.SharpDX\Controls\DPFCanvas.cs:line 753


However, I think this is a bit misleading. When I look at the code, it is failing on line 102 of DX11ImageSource:


this.renderTarget = new Texture(DX11ImageSource.device, target.Description.Width, target.Description.Height, 1, Usage.RenderTarget, format, Pool.Default, ref handle);      

With the following exception thrown: 


'SharpDX.SharpDXException' in SharpDX.dll
HRESULT: [0x80070057], Module: [General], ApiCode: [E_INVALIDARG/Invalid Arguments], Message: The parameter is incorrect.


I even tried making my own possibly simpler project and using NuGet to import the helixtoolkit libraries and I get the same error. At home I can execute everything on my personal computer so it appears to be some (mis)configuration on my work laptop. Both machines are Windows 10, using VS2017 with AFAIK updated drivers. I'm not sure where to go from here to diagnose the error.


I have also tried Microsoft's WPF DirectX Extensions (https://github.com/Microsoft/WPFDXInterop) and it works properly. Finally, I tried compiling SharpDX but it doesn't include any sample code for me to run. If anyone has any suggestions, I'd love to hear them.

Problem with transparent background at TextVisual3D

MarioR 1 year ago in Question 0

Hello,

is it correctly that the TextVisual3D only display the transparent backgorund from last insert TextVisual3D?



        <helix:HelixViewport3D ZoomExtentsWhenLoaded="True" ShowCoordinateSystem="True"  CameraMode="Inspect">
            <helix:SunLight />
            <helix:TextVisual3D Position="1,-1,1" Text="Hello"  Foreground="Aqua" Background="Transparent" UpDirection="0,0,1"  Height="1"/>
            <helix:GridLinesVisual3D Width="10" Length="10" MinorDistance="1" MajorDistance="1" Thickness="0.01"/>
            <helix:SphereVisual3D Center="0,0,0" Radius="0.5" />
            <helix:EllipsoidVisual3D Center="3,3,3" RadiusX="2" RadiusY="3" RadiusZ="4" />
        </helix:HelixViewport3D>




        <helix:HelixViewport3D ZoomExtentsWhenLoaded="True" ShowCoordinateSystem="True"  CameraMode="Inspect">
            <helix:SunLight />
            <helix:GridLinesVisual3D Width="10" Length="10" MinorDistance="1" MajorDistance="1" Thickness="0.01"/>
            <helix:SphereVisual3D Center="0,0,0" Radius="0.5" />
            <helix:EllipsoidVisual3D Center="3,3,3" RadiusX="2" RadiusY="3" RadiusZ="4" />
            <helix:TextVisual3D Position="1,-1,1" Text="Hello"  Foreground="Aqua" Background="Transparent" UpDirection="0,0,1"  Height="1"/>
        </helix:HelixViewport3D>



If flip in view from backside is transparency not work on other TextVisual3D.

        </helix:HelixViewport3D>
