使用 HelixToolkit 显示 3D

Question

Is there any code that I can use to display my 3D model ? , I Tried using HelixToolkit but i don't know how to use it, can anyone show me with a piece of code to just load a 3D Obj file

Answer 1

I'm assuming you've used Nuget to download the Helix3D libraries, but if you download the source code from GitHub then this includes an extensive ExampleBrowser application that gives guidance of how to use Helix3D

Helix3D on GitHub

My application is structured as follows:

XAML

    <h:HelixViewport3D x:Name="HelixViewport3D" ShowViewCube="False">
        <h:DefaultLights/>
        <ModelVisual3D x:Name="MyModel"/>         
    </h:HelixViewport3D>

C#

  var scene = new Model3DGroup();
  scene.Add(Load3dObject(@"C:\filename.obj"));
  MyModel.Content = scene;

Which calls this helper function Load3dObject I created to help clean up the code.

    private Model3D Load3dObject(string objName)
    {
        var reader = new ObjReader();
        var modelGroup = reader.Read(objName);
        return modelGroup;
    }
