How to Build 3D Apps with Visual Basic Studio You can build functional 3D applications in Visual Studio using Visual Basic (VB.NET) by pairing the language with modern .NET graphics libraries. While Visual Studio historically included built-in 3D model editors, security changes have phased out native modeling features. Today, developers rely on external 3D libraries like Helix Toolkit or OpenTK to handle the rendering pipeline within a standard Visual Basic environment.
This guide walks you through setting up a 3D workspace, integrating a third-party framework, and rendering your first interactive 3D object using Visual Basic. Prerequisites and Setup
To follow this tutorial, you need Visual Studio installed with the .NET desktop development workload. Open Visual Studio. Select Create a new project. Filter the language to Visual Basic.
Choose WPF Application or Windows Forms App (WPF is highly recommended for 3D due to its native hardware acceleration).
Name your project and target a modern framework like .NET 8.0. Step 1: Choosing a 3D Graphics Library
Visual Basic does not have a native “drag-and-drop” 3D button in the standard toolbox. Instead, you must install an open-source library via the NuGet Package Manager:
Helix Toolkit: Best for WPF applications. It provides high-level 3D controls, making it easy to add cameras, lights, and basic shapes.
OpenTK: Best for cross-platform or lower-level control. It provides a direct wrapper around OpenGL.
WaveEngine / Evergine: Suited for full industrial 3D visualization or game development.
For this guide, we will use Helix Toolkit due to its seamless integration with WPF and Visual Basic. Open your NuGet Package Manager Console (Tools > NuGet Package Manager > Package Manager Console) and run: Install-Package HelixToolkit.Wpf Use code with caution. Step 2: Defining the 3D Viewport (XAML)
The layout must define where the 3D world exists. Open your MainWindow.xaml file and declare the Helix Toolkit namespace. Replace your core XAML grid with the following viewport structure:
With the interface prepared, you can write the logic to construct a 3D mesh. Right-click your main form and select View Code to open MainWindow.xaml.vb. Use the following code to build a basic 3D cube and bind it to the viewport:
Imports System.Windows.Media.Media3D Imports HelixToolkit.Wpf Class MainWindow Private Sub MainWindow_Loaded(sender As Object, e As RoutedEventArgs) Handles Me.Loaded ‘ 1. Initialize a Mesh Builder to construct shapes Dim meshBuilder As New MeshBuilder(False, False) ’ 2. Create a standard 3D Box/Cube (Center, Width, Length, Height) meshBuilder.AddBox(New Point3D(0, 0, 0), 2, 2, 2) ‘ 3. Convert the builder instructions into a real geometry mesh Dim mesh As MeshGeometry3D = meshBuilder.ToMesh() ’ 4. Define a material and color for the object Dim material As Material = MaterialHelper.CreateMaterial(Colors.DodgerBlue) ‘ 5. Combine geometry and material into a single renderable model Dim model As New GeometryModel3D(mesh, material) ’ 6. Assign the model to a Visual3D wrapper and add it to the UI Dim visualModel As New ModelVisual3D() visualModel.Content = model ‘ Add to the Viewport defined in XAML modelContainer.Children.Add(visualModel) End Sub End Class Use code with caution. Step 4: Testing Your Application
Press F5 to compile and run your project. You will see a 3D blue cube floating in space. Because you used Helix Toolkit, interactive features are built-in automatically: Right-click and drag to rotate the camera around the cube. Scroll wheel to zoom in and out. Middle-click and drag to pan across the viewport. Advanced Next Steps
