Shader Showcase Saturday #4: How To Start A Fire With Shaders

In the two previous instalments of Shader Showcase Saturday, we have talked about waterfalls and interactive grass. Those two subjects sound very different from each other, yet they share something in common: the original phenomenon can be modelled as a fluid simulation. This week’s Shader Showcase Saturday will continue this trend, talking about another effect that involves fluids: fire.

Shader Showcase Saturday #2: Waterfalls

Historically speaking, waterfalls have always had a special place in games. From Super Mario to Tomb Raider, their role has been more than just aesthetic. Often hiding secret caves, waterfalls are now iconic. This is why I believe is important to celebrate some of the most well-crafted waterfalls that have been posted online in the past few months.

I hope this will encourage more readers to try out what shaders can really do, especially when it comes to rivers, lakes and oceans.

Shader Showcase Saturday #1: Volumetric Crystals

When a 3D object is drawn on the screen, only its outer shell is actually rendered. This works for most solid and opaque materials, but is not powerful enough to bring life to transparent and translucent materials. Currently, this is one of the biggest limitations of most modern game engines. Volumetric rendering is a technique that allows rendering materials with a complex internal structure. The topic has been covered extensively on a tutorial tilted Volumetric Rendering, specifically designed for Unity.

In this post, however, I want to highlight some of the best volumetric effects that I have recently seen on the Internet. Not all the effects shown here might be actually using volumetric rendering, but they all give the illusion of being more than just empty shells.

Learning Shaders

Making games is hard. Engines like Unity and Unreal have massively lowered the barrier to entry into this industry. And now that making games is easier than it has ever been before, developers are facing a new crisis. More and more people are joining this industry every day, making it harder to succeed in such an overcrowded market.

Many games that were popular and successful five years ago, would go mostly unnoticed today. More skills are needed to make a game stand out from its competitors, and this is why I believe that learning shaders is so important.

Shaders are the paintbrushes developers use to render graphics. The look and aesthetic of many iconic games, such as Journey, Antichamber and No Man’s Sky, was made possible only by the clever use of shaders.

Whether you are a new developer wanting to make games, or a veteran of the industry, learning how to write shaders can make the difference. This unusual tutorial pays homage to some of the best online content creators that you should know if you want to start your journey into shader coding. Continue reading
