@ryo @xianc78 i wrote my cinematic script system so its easy to move between engines but i still have to go deal with adding the demo project stuff

was sorta hoping to be further along a project by now though. trying to get odd jobs online didn't really pan out.

@ryo @icedquinn This guy managed to do it. He even has a full tutorial on how to do it.

Honestly, people using these engines need to ask themselves if they really need all those bloated features that engines provide. Does your game really need to be in 3D? Does it really need VR support? Does it really need RTX graphics?

@xianc78 @icedquinn 3D is nice to have, I think you'd even stand out as an indie if you do 3D.
But I know it's extremely hard unless you have some insane 3D mathematics skills.

I'll bookmark this site, will come in handy when I will make a game again, as last time I did was a decade ago, and it was in Unity too.

@ryo @xianc78 i implemented the suite of linear algebra to do basic 2d/3d stuff. and some projective geometric algebra.

it wasn't all that fun.

business doesn't really care about anything other than shipping the product. so there's a limited amount of effort that is worthwhile when it comes to things like rewriting the world to use projective algebra because its intellectually pure but the somahead at the end of the steam sale couldn't care less.

@ryo @icedquinn I've taken a 3D graphics class back in college. It's pretty simple if you know linear algebra. The professor even wrote his own 3D renderer that outputs to a JFrame image object. For my senior project the following year, I was tasked to rewrite it in JavaScript and port it to HTML5 canvas.

Honestly, the hardest part is the clipping and accounting for the fact that object behind the camera will appear in front of the camera and upside down unless you specifically tell the program not to render them.

However, we were never taught how to map textures or even shade polygons. I wanted to add that feature in my JS port but I didn't have time.

@ryo @icedquinn @xianc78 GPU 3d graphics from scratch is doable for the average dev

Mostly basically boilerplate

3d physics from scratch would be a fair bit harder. If you did 2d gameplay but 3d graphics it would be sane

This is basically the opengl tutorial + math library (basically copying equations) + assimp (making your own OBJ importer is easy tho) + my code
