Introduction
The Spray Paint VR project is a Native VR experience built for the Meta Quest platform. This interactive application allows users to spray paint various parts of a car in a virtual environment using VR controllers. Built with Unity and the Oculus SDK, this project provides an immersive and creative way to experiment with colours and designs in a virtual 3D space.
Features
Interactive Spray Painting: Users can spray paint on specific parts of a car with realistic effects.
Customizable Colors and Tools: A palette of colours and spray options is available to enhance the creative experience.
Immersive VR Controls: Leverages Meta Quest controllers for intuitive painting gestures.
Real-Time Feedback: Visual feedback mimics real spray paint behaviour with fade, opacity, and blending effects.
Dynamic Environment: The virtual environment adjusts to the user’s interactions, providing an engaging workspace.
Requirements
Device Compatibility: Meta Quest or Meta Quest 2 headset.
Software Framework: Unity 2020 or later, Oculus Integration SDK.
Hardware: VR-ready PC for development (if customizing) or standalone headset for deployment.
Controllers: Meta Quest controllers for interaction.
Usage
Setup: Ensure the Meta Quest headset is powered on and connected.
Launch: Start the application from the library or sideload it onto the Quest.
Select Tools: Choose colours and spray settings from the in-app menu.
Paint: Use the VR controllers to spray paint on car surfaces:
Trigger Button: Activates the spray paint.
Joystick: Adjust the view or reposition the spray can.
Experiment: Combine different colours and techniques to create unique designs.
Scripting
The application relies on several key components:
Spray Paint Mechanics: Particle systems simulate realistic spray effects, including opacity, spread, and fall-off.
Controller Mapping: Oculus SDK handles controller inputs and interactions.
Shader Development: Custom shaders ensure accurate rendering of paint textures and blending.
Performance Optimization: Techniques such as frustum culling and optimized mesh rendering ensure smooth performance on standalone devices.
