What are the basics of 3D rendering using C++ graphics API?

3D rendering involves creating a 2D image from a 3D model using a graphics API like OpenGL or DirectX in C++. It includes steps like setting up a rendering context, defining geometry, applying textures, and managing lighting.

Can you explain how lighting works in 3D rendering?

Sure! Lighting in 3D rendering simulates how light interacts with surfaces. Common types include ambient, diffuse, and specular lighting, each affecting how objects appear based on their material properties and light sources.

What is the role of shaders in rendering?

Shaders are programs that run on the GPU to control the rendering pipeline. They determine how vertices and pixels are processed, allowing for effects like texture mapping, lighting calculations, and more.

How do I get started with OpenGL in C++?

To get started with OpenGL in C++, you'll need to set up a development environment, install necessary libraries like GLFW and GLEW, and write a basic program to create a window and render a simple shape.
