3D on scratch, And how it's professionally accomplished

If it were just 2D math, you wouldn’t get true occlusion, perspective, or 3D rotations. So really, both points are valid: the screen shows a 2D projection, but the underlying space is real 3D.”

The only manipulative thing over here is your attitude, trying to shift the topic from the result on your screen to the 3D calculations that happen behind the scenes, which, to blow your mind, get turned to 2D screen coordinates later on. that's it, that's the end of discussion, and no one here followed this forum to discuss chatgpt. end of discussion

How do you make this infinitely long line?

mathmatical construct really, just as you make vectors on scratch, which aren't really vectors but a pair of similar variables!

Used ChatGPT again…

okay, now what that message says is correct, we were not saying the ENTIRE game was an illusion, the 2D projection is an illusion!!! The game engine is 100% 3D. also using ChatGPT for stuff is not reccomended, people know more than an AI. an AI can be wrong, it is programmed, not a brain. AI can help, maybe… but other people with a lot of experience can be better than an AI.

Hopefully this argument is solved now.

How did you learn to do all of this? I already have a basic understanding of how these 3d games work, and I want to be able to make these without following tutorials and know what I'm doing. I already made some 3d projects and I want to get into the more advanced things without following tutorials. Also how do you make your 3d projects, do you have a process on how to do things? Just curious

When I was learning 3D I did tutorials but I used some information and used the basics and made a different one than the tutorial ones. it depends what you want. you always need a tutorial to understand the 3D logic and how it is performed. once you know information try to make your own. not sure how to help you in this case. maybe @GL00B knows?

That's all my friends, would hugely appreciate if you followed me and shared your opinions on the topic below, if you have any questions, I'll make sure to answer them, peace!

The likes in your Daytona USA doesn't increase directly so I'm waiting patiently for a tutorial because I wanna make a 3d racer too, also btw I'll credit you

I made a 3d engine https://scratch.mit.edu/projects/1209316791 but it culls right before render so it still sorts the triangles out of the view frustum and backfacing triangles I have tried to cull when it calculates distances but I can't figure it out. (it uses codingbios tutorials) also can you tell me if the triangle collison or mesh importer is slowing it down ?

Idk I just only made a simple 3d maze but btw IM GONNA MAKE A 3D RACE GAME WITH ALEX STEVE TUTORIAL AND SCROLLING ITEMS AND BACKGROUND!

when green flag clicked
forever
Create 3D car
end

According to Alex Steve's tutorial

And road scroll with 2 sprites
