how to create your own game engine in c++

I began my trip with game engines a while ago using my Mac. Some of the best AAA games are built with those.

They were initially designed with building games in mind - and it shows. These engines can do absolutely anything. In the game development scene, you have those big game engines capable of going everything out of the box, like Unreal Engine, Unity, CryEngine. But what if we don’t want to build a game? What if we wish to run a 3D simulation, visualize some data, view some models, or work in a simple AR application? AAA Game engines Then you have physics engines, sound engines, gameplay engines, AI engines.įortunately, we have Game Engines to help us abstract away from all those annoying things, lifting the developer’s burden and allowing us to concentrate on what matters: our game. Quaternions, matrix transformations, how this applies to raycasting, how lighting works (To name a few).Īfter the theoretical parts, here come the practical ones: File formats (PNG, GLTF, importers), meshes, graphics specifications (OpenGL, WebGL, Vulkan, Metal). 3D graphics is an entire philosophy that involves something that many software engineers dread Mathematics. Most of the developers I have talked to in my life have a pretty vague idea of what goes into creating a game - or even using them. Game EnginesĪh, the sweet holy grail of most of the Software Engineers I have encountered. The 3D graphics scene is vast, and this is more like a documentation of my approaches and experiences with a few solutions rather than a comparison of the top frameworks. Some of the technologies I will talk about may surely be popular, but that’s not the point. Judging by the plethora of the frameworks intended for the Creative Scene, I had to do a lot of work before I started to do any work :).ĭisclaimer: This is not another “top X” post. Something that no one had warned me about before I decided to develop 3D software was that it would be challenging to decide what to start with. I have never created any 3D games, but there are many times where I needed to create a 3D physics simulation or present a 3D scene in response to a stream of data received as input. One of those domains is 3D graphics creation for Native Applications, desktop showcases, or the Web. The sheer amount of joy I take when coding something has led me to develop projects spanned across many software domains. If you are like me, nothing is giving you more thrills than to write or design software. 12 min read A trip through popular 3D frameworks for creative purposes.
