SLC Mechanical training / Part 4 (VR)

Introduction

This tutorial will guide you through creating an interactive VR experience for mechanical models using SimLab Composer. By the end of this guide, you'll know how to incorporate animations, simulations, lighting, and material options into your VR projects. This experience can be viewed on various devices, including HTC Vive, Oculus Rift, desktops, and mobile devices.

Step 1: Setting Up SimLab Composer

Download and Install SimLab Composer

• Go to the SimLab website and download the latest version.
• Follow the installation instructions specific to your operating system.

Start a New Project

• Open SimLab Composer and create a new project.
• Familiarize yourself with the interface, including the toolbar and properties panel.

Step 2: Importing Mechanical Models

Import Your Model

• Use the ‘Import’ option to bring your 3D mechanical model into the project.
• Supported formats include OBJ, FBX, and STL.

Position and Scale

• Adjust the position and scale of your model using the transform tools.
• Ensure the model is centered in the scene for optimal viewing in VR.

Step 3: Adding Interactivity

Creating Animations

• Select the components of your model you want to animate.
• Access the animation panel and set keyframes to define the motion.
• Preview your animation to ensure it runs smoothly.

Setting Up Simulations

• Use the simulation tools in SimLab Composer to add physics to your model.
• Define parameters like gravity and collision to create realistic interactions.

Step 4: Enhancing Visuals

Lighting Options

• Access the lighting settings to add ambient light, directional light, or point lights.
• Experiment with different settings to enhance the model's visibility and aesthetics.

Material Customization

• Select the model components and open the material editor.
• Adjust properties such as color, texture, and reflectivity to achieve your desired look.

Step 5: Exporting for VR

Setting Up VR Export

• Once your model is ready, navigate to the VR export settings.
• Choose the appropriate settings for your target VR device (HTC Vive, Oculus Rift, etc.).

Exporting the Project

• Click on the export button and select the VR option.
• Save the project in a location accessible for your VR devices.

Step 6: Testing the VR Experience

Launching the VR Experience

• Connect your VR headset and launch the SimLab VR viewer.
• Load your exported project and explore the interactive features you’ve created.

Gathering Feedback

• Share your VR experience with others and gather feedback for improvements.
• Make adjustments based on user interaction and preferences.

Conclusion

You have successfully created an interactive VR experience for mechanical models using SimLab Composer. Key steps included importing your model, adding animations and simulations, customizing lighting and materials, and exporting for VR viewing. As a next step, consider experimenting with more complex animations or integrating user inputs to further enhance interactivity in your VR projects. Happy creating!
