Z-Buffer 3D Rendering Application

Welcome to the Z-Buffer 3D Rendering Application, a simple yet powerful tool for rendering three-dimensional objects using the Z-Buffer algorithm. This application is built using C++ and Qt for the graphical interface.

Introduction

The Z-Buffer 3D Rendering Application demonstrates the implementation of the Z-Buffer algorithm for efficient and accurate rendering of 3D scenes. It includes basic geometric shapes like cones, spheres, and cubes, showcasing the versatility of the Z-Buffer rendering technique.

Features

• Z-Buffer Rendering: Utilizes the Z-Buffer algorithm to achieve pixel-perfect depth calculations.
• Object Variety: Renders cones, spheres, and cubes, providing a diverse set of 3D objects.
• Interactive Rotation: Allows users to interactively rotate objects around the X, Y, and Z axes.

How to Use

1. Clone the repository to your local machine.
2. Open the project in a C++ development environment that supports Qt.
3. Build and run the application.
4. Explore the rendered 3D objects and use the interactive rotation controls.

Code Overview

• The zbuffer class extends QLabel and serves as the main application window.
• Objects are constructed and stored using the build_objects method, representing cones, spheres, and cubes.
• Rotation functions (rotate_objects_X, rotate_objects_Y, rotate_objects_Z) allow interactive manipulation of objects.
• The zbufferRender method initializes the Z-Buffer and triggers rendering.
• Painting operations are batched for efficiency, with points sorted based on Z-coordinates.
