Python doesn’t have a built-in array data type, however, there are modules you can use to work with arrays. This article describes how to add to an array using the array and the NumPy modules. The array module is useful when you need to create an array of integers and floating-point...
In this step-by-step tutorial, you'll learn about MATLAB vs Python, why you should switch from MATLAB to Python, the packages you'll need to make a smooth transition, and the bumps you'll most likely encounter along the way.
The tutorial will demonstrate the basics of rendering - transforming objects from 3D space into 2D images.To make it simple and fast (realtime!), the script will draw only vertices. The image will be redrawn every time the viewport is updated - changing the view, panning, zooming and orbit...
