So far in the series we've covered the key aspects of how shapes in a scene are moved and manipulated, transformed from a 3-dimensional space into a flat grid of pixels, and how textures are applied to those shapes. For many years, this was the bulk of the rendering process, and we can see this by going back to 1993 and firing up id Software's Doom...
To do any of this properly, you need to be able to accurately model how light behaves as it interacts with different surfaces. You might be surprised to know that the origins of this dates back to the 18th century, and a man called Johann Heinrich Lambert. In 1760, the Swiss scientist released a book called Photometria -- in it, he set down a raft ...
When we looked at vertex processing and rasterization, we saw that the results from all of the fancy lighting calculations, done on each vertex, have to be interpolated across the surface between the vertices. This is because all of the properties associated the surface's material are contained within the vertices; when the 3D world gets squashed i...
Let's take a look at Ubisoft's 2018 title Assassin's Creed: Odyssey– this game forces you to spend a lot of time sailing around on water, be it shallow rivers and coastal regions, as well as deep seas. Painted wood, metal, ropes, cloth, and water – all reflected and refracted using a battery of math To render the water as realistically as possible,...
Let's use the Shadow of the Tomb Raiderto start our next section of this article. In the image below, all of the graphics settings related to shadows have been disabled; on the right, they're all switched on. Quite the difference, right? Since shadows occur naturally around us, any game that does them poorly will never look right. This is because o...
A more accurate way to do shadows was proposed much earlier than this, all the way back in 1977. Whilst working at the University of Austin, Texas, Franklin Crow wrote a research paper in which he proposed several techniques that all involved the use of shadow volumes. Generalized, the process determines which primitives are facing the light source...
In this article, we've tried to cover some of the fundamental math and techniques employed in 3D games to make them look as realistic as possible, looking at the technology behind the modelling of how light interacts with objects and materials. And this has been just a small taste of it all. For example, we skipped things such as energy conservatio...

Jan 20, 2023 · Introduction. The appearance and feel of a 3D scene in a video game can be greatly influenced by lighting, which is an important component of the creation of a 3D video game. Lighting is often managed in a game engine by a system of lights and materials that specify how objects in the scene are illuminated and interact with light. Aside from ...

Complex baked lighting may involve calculating many bounces. The more bounces the more accurate the lighting will be, but the longer this will take. Luckily though we save the baked lighting afterwards, so only the developers have to wait for this to calculate. In older games most shadows used to be baked.
