This is the second part of Fractals 101, a series of tutorial dedicated to fractals. This post will investigate two popular fractals: the Mandelbrot set and its 3D cousin, the Mandelbulb.
This new series of tutorials will explain what fractals are, why they are so important and what we can learn from them. This first lesson is a gentle introduction to the concept of iterated fractals and their dimension.
Since fractals naturally occur in nature, this series will be particularly interesting to all artists and game developers who want to create realistic outdoor environments.
This is the second part of a tutorial that will teach you how to build a portable heating device with Arduino. In this post, we will explore how to control a heating resistor with Arduino. This allows to keep your setup at the desired temperature.
This tutorial will explain how to build a portable heating device with Arduino. If you’re an amateur astronomer, this can be the perfect way to prevent the formation of dew on your mirrors and lenses. In my specific case, I’ve built one of those mini heaters to warm up a formicarium. Whether it’s for your feet or for your cold-blooded pets, building a heater is easy and cheap.
The second part of this tutorial (How to Build a Heater with Arduino – Part 2) will explain how to use a temperature sensor to maintain a desired temperature. Continue reading
This tutorial explains how to create complex 3D shapes inside volumetric shaders. Signed Distance Functions (often referred as Fields) are mathematical tools used to describe geometrical shapes such as sphere, boxes and tori. Compared to traditional 3D models made out of triangles, signed distance functions provide virtually infinite resolution, and are amenable to geometric manipulation. The following animation, from formulanimation tutorial :: making a snail, shows how a snail can be created using simpler shapes:
