## Core Idea

This article teaches how to build a software renderer from scratch to understand the workings of modern 3D graphics libraries like OpenGL and Vulkan. Students learn basic rendering techniques with just 500 lines of C++ code.

## Starting Point

The project begins with a simple class for handling TGA files, without any external libraries. Students build the rendering process step by step, starting with basic functions like pixel coloring.

## Learning Process

Students spend 10-20 hours coding to implement basic rendering techniques like triangle drawing and texture mapping. This process helps them grasp the underlying logic of 3D graphics APIs.

## Practical Application

The article encourages students to write their own renderers. Instead of using ready-made code, they implement each step themselves to gain a deep understanding.

## Results

The completed project produces a software capable of rendering a simple 3D model. This concretely demonstrates the basic workings of modern graphics libraries to students.

## Significance

This training provides an ideal starting point for those looking to dive into 3D graphics programming. Learning the core concepts enhances efficiency when using more complex graphics APIs.
