javidx9 demonstrates how to build a 3D graphics engine from scratch, starting with triangles and projection matrices.

This video is part #1 of a new series where I construct a 3D graphics engine from scratch. I start at the beginning, setting up the project, then discuss vertices and triangles. Next a description of how 3D coordinates are converted into on-screen 2D coordinates using a projection matrix. This results in seeing a cube being rotated in 2-axis and translated.

What people say. Highly recommended for learning 3D graphics concepts, software rendering, and game engine math from scratch.

On “(C/C++)ASCII frame buffer and z buffer?”

Have a look into Javidx9 Code it yourself playlists. It contain a series where he try to create a 3D graphics engine. He introduces a bunch of 3D concept like Normals, Culling, Lighting , Object Files, Projection, camera, clipping, texturing and depth buffer. Here is the first video which show how to create a cube : [video

On “C Hands-On?”

I looked at the 3D rendering stuff (I was interested in software-rendering), but I have since found a video series on Youtube. I regularly look at some videos from Handmade Hero if I'm learning about a new topic.

On “Learning C by drawing GUI from scratch”

I just thought about people creating game engines from scratch. There are detailed videos on this. They probably do a lot of stuff you want to do, since game engines are very heavy on the graphic and usually need to provide their own widgets etc. [video [video (A god but coding in c++) Maybe thats interessting to watch and get a grasp which does what. Hope you have fun.

Strange bug while translating a tutorials code to another language I'm pretty much totally new to graphics programming. The original is soley implemented in C++, but for easy reusablity I decided to translate it into native python (Of course using numpy and C extensions for all heavy work). I was following this tutorial. And at the z offset step ~35:40-36:15, my version started behaving strangly, I currently blame my 4x4 matrix multiplication, but I really have no idea. I also tried to use the Python Translation's function, but that collapsed the projection into a single point (until it rotates it), which also isn't the behaviour observed in the tutorial.
