Rainbow Triangle

A high-performance graphics demonstration written in Rust using the wgpu library. This project showcases a modern rendering pipeline setup, including vertex/fragment shaders and uniform buffer manipulation for real-time transformations.

Features

• WGPU Rendering: Utilizes the WebGPU API for cross-platform, low-level graphics access.
• Real-time Transformations:
  • Rotation: Rotates the geometry around the Z-axis.
  • Scaling: Pulses the size of the triangle dynamically.
  • Wobble: Applies a time-based distortion effect via uniforms.
• Shader Pipeline: Custom WGSL shaders for vertex and fragment processing.
• Uniform Buffers: Efficient CPU-to-GPU data transfer for transformation matrices and time variables.

Prerequisites

• Rust (latest stable toolchain)
• A graphics driver with Vulkan, Metal, DX12, or GLES3 support.

Getting Started

1. Clone the repository:

   git clone https://github.com/your-username/rainbow_triangle.git
   cd rainbow_triangle

2. Run the application:

   cargo run

   Note: Check cargo run -- --help to see available command-line flags for enabling rotation, scaling, or wobble effects.

Tech Stack

• wgpu: Safe and portable GPU abstraction.
• winit: Window creation and event handling.
• glam: Fast linear algebra for rendering math.
• bytemuck: Zero-cost casting for buffer data.
• clap: Command-line argument parsing.
