Overview

miniRT is a RayTracer program that generates images of scenes using the Raytracing protocol. Each image represents a scene as seen from a specific viewpoint, defined by simple geometric objects and lighting systems. The project aims to create realistic computer-generated images using concepts of light reflection and refraction.

Features

• Geometric Objects: Supports at least three simple geometric objects: plane, sphere, and cylinder.
• Scene Description: Parses a scene description file (*.rt) to set up the scene with cameras, lights, and objects. Examples of *.rt files are included in maps/.
• Transformation: Allows translation and rotation transformations for objects, lights, and cameras.
• Lighting: Implements ambient and diffuse lighting, spot brightness, hard shadows, and ambiance lighting.
• Window Management: Ensures fluid window management with the miniLibX library, handling window resizing and closure events cleanly.
• Error Handling: Properly exits with error messages for any misconfiguration encountered in the scene description file.

User Controls

Move Camera - Arrow keys

• 8 (Up): Move camera up.
• 6 (Right): Move camera right.
• 4 (Left): Move camera left.
• 2 (Down): Move camera down.

Zoom In/Out:

• +: Zoom in.
• -: Zoom out.

Note:

• The dimentions of the window are defined in includes/scene.h as CANVAS_WIDTH and CANVAS_HEIGHT.
