3D Graphics Engine

Overview

This 3D graphics engine is designed to render 3D models and textures in a console environment. It leverages the olcConsoleGameEngine, providing a unique approach to 3D rendering in a non-traditional medium.

Features

• 3D Model Rendering: Render 3D objects within a console interface.
• Texture Mapping: Apply textures to 3D models for enhanced visuals.
• Camera Control: Basic camera movements and rotations for dynamic viewing.

Getting Started

Prerequisites

• C++ compiler
• olcConsoleGameEngine - Ensure this is downloaded or cloned from its repository.

Installation

1. Clone or download this repository.
2. Compile and execute the application.

Usage

Loading Models

Use mesh::LoadFromObjectFile to load 3D models from .obj files into the engine.

Camera Controls

• Movement: Utilize arrow keys for moving the camera.
• Rotation: Use 'W', 'A', 'S', 'D' keys to rotate the camera.

Code Structure

Key Components

• vec2d, vec3d: Vector structures for 2D and 3D coordinate representation.
• triangle: Represents a 3D triangle, essential for 3D model construction.
• mesh: Manages 3D model data including vertices and texture information.
• mat4x4: A 4x4 matrix for handling various transformations.
• olcEngine3D: Extends olcConsoleGameEngine, central to the rendering process.

Notable Methods

• Matrix and Vector Operations: Functions like Matrix_MultiplyVector, Vector_Add for mathematical computations.
• Rendering Logic: The OnUserUpdate method is where the core rendering logic resides.
