Explosive Chaos: Jinx’s Playthings

Project Overview

This project showcases a dynamic 3D scene using OpenGL, inspired by Jinx from Arcane, highlighting her explosive personality and unique "toys." The scene implements advanced lighting models, texture mapping techniques, and efficient scene management to create a visually captivating environment.

Key Features

Lighting Models

• Blinn-Phong Lighting Model: Achieves realistic illumination by combining ambient, diffuse, and specular components. It uses a half-vector for realistic highlights and light attenuation to enhance distance perception.
• Cel Shading: Provides a sketchy, stylized appearance to key objects such as the Hextech crystal. Colors are assigned based on discrete intensity thresholds, creating a dark silhouette through:
  • A second render pass with expanded normals and front-face culling.
  • Rim lighting to emphasize glowing edges, mirroring the Arcane aesthetic.

Texture Mapping

• Normal Mapping: Enhances surface details by simulating depth and intricate textures, such as metal roughness and engravings. RGB normal maps are used to modify light interactions.
• Procedural Texture Generation:
  • Wood: Smooth noise with linear interpolations for realistic grain patterns.
  • Marble & Brick: Rougher noise with multi-octave accumulation using cubic interpolations. Gradients are mapped to grayscale pixel values and converted to realistic colors.

Scene Graph Management

Efficient handling of transformations, shaders, hierarchical relationships, and other elements is managed through a scene graph, ensuring smooth scene complexity management.
