Overview

This is a RESTful Web chat application that includes a pong game developed with the following stack:

• Typescript
• ReactJs
• NestJs
• Postgresql with Prisma database ORM
• Docker for containerizing the application features
• Websockets API

Mechanism

The application is designed to authenticate users using 42 authentication. We included JWT for the identification of each user and for generating tokens that will remember each user settings. Users can add each other as friends, chat with them as well as inviting them to a multiplayer pong game. There are set of roles on each room: owner, administrator, and other users; each one of those roles has its specific privileges and permissions over the room. A user can set his profile and update it with a new name and picture. The games are live and can be watched.

Overview

MiniRT is a captivating project in the realm of computer graphics, meticulously crafted in C to explore the mesmerizing world of ray-tracing. This project endeavors to project geometric shapes, including cylinders, planes, and spheres, onto a canvas using the principles of ray-tracing.

Key Concepts

• Ray-Tracing Simulation: At the heart of MiniRT lies the concept of ray-tracing, a rendering technique that simulates the interaction of light rays with objects in a scene. By projecting rays from the observer's viewpoint and tracing their path as they interact with objects, MiniRT recreates realistic images with stunning accuracy.
• Intersection Calculation: Central to the ray-tracing process is the calculation of intersections between rays and geometric primitives such as spheres, cylinders, and planes. MiniRT employs advanced algorithms to accurately determine these intersections, enabling precise rendering of objects in the scene.
• Shading and Lighting: To imbue the rendered scene with realism, MiniRT incorporates shading and lighting effects. By projecting secondary rays towards light sources and calculating shadow intersections, MiniRT simulates the interplay of light and shadow, resulting in lifelike imagery.

Skills Required

• Linear Algebra Proficiency: Understanding vectors, matrices, and their operations is essential for implementing the mathematical foundations of ray-tracing in MiniRT.
• Quadratic Equation Solving: Proficiency in solving quadratic equations is crucial for accurately determining intersections between rays and geometric primitives.
• Ray-Tracing Fundamentals: Familiarity with the principles of ray-tracing, as outlined in resources like scratchapixel.com, provides the conceptual framework necessary to implement MiniRT's rendering pipeline.
