OpenGL

Whether you just want to create an interactive 3D logo, on the screen or design a fully fledged game, knowing the principles of 3D graphics rendering will help you achieve your goal. In this article, Toptal Freelance Software Engineer Adnan Ademovic gives us a step-by-step tutorial to rendering objects with textures and lighting, by breaking down abstract concepts like objects, lights, and cameras into simple WebGL procedures.

OpenGL, a cross-platform API for rendering 2D and 3D graphics, is extremely powerful and yet surprisingly easy to get started with. Although one may find the most common applications of OpenGL and rendered graphics in video games only, in reality there are far more uses. To demonstrate the power of OpenGL, we'll be building a Mandelbrot set generator on Android using OpenGL ES.

Over time, the race between DirectX and OpenGL has caused these technologies to become more accessible to developers, along with better documentation and an easier process of getting started with them. This tutorial article shows you how to build a 3D modeling application that generates and renders 3D texts from user inputs.

When people think computational geometry, in my experience, they typically think one of two things: 1. Wow, that sounds complicated. 2. Oh yeah, convex hull. In this post, I'd like to shed some light on computational geometry, starting with a brief overview of the subject before moving into some practical advice based on my own experiences in computational geometric programming with Python.
