Fantastic explanation. You go over each concept in detail while using solid visual examples to show people exactly what you are talking about - the best possible way to help people understand.

[electrisipio]

Maybe the best and simple explanation so far..!!
Well Done! and thanks!

[NERDfirst]

Cheers! That's the whole point of me doing what I do. I want to help others, that's why I'm making these videos in the first place =)

I'm very glad to know I helped you, Cole. Have fun working with 3D Graphics =)

[NERDfirst]

Hello and thank you very much for your comment! Glad you liked the video =)

[SebFehr]

Thanks, straight to the point, in plain English. Just the concise explanation I was looking for.

[MaxtronZero]

Thanks for the Video, very well explained.

Do you think you could do a tutorial on 3D rendering on its own? I have a 3DS running petit computer, and it doesn't have 3D rendering commands. Is there a way I can have 3D rendering by having a 3D render engine in the code which will then put the objects on screen? I am pretty possible it's gonna be slow, but I still want to do it. :)

Hello again! =)

I never got past the wireframe stage myself =P That already took quite a lot of calculations, and it was doubly hard to do on a touchscreen mobile device.

Petit Computer runs BASIC though, doesn't it? Perhaps you could study some open source BASIC 3D library, and that would help you greatly. You might even be able to port it, if there isn't too much code.

[ColeslawProd]

Great idea! I'll look into that. I'm glad someone smart like you just tries to help me even if you don't really know who I am! My name is Cole if you were wondering. :)

[ColeslawProd]

I mean, I will be satisfied with just how to do simple wireframe 3D rendering if mapping textures and lighting is too difficult. Plus, petit computer is a kind of obscure app, so I don't know if many libraries are written for its language, but I'll check anyway. I'll tell you if I find something. :)

[NERDfirst]

Haha I managed to pick up on that anyway =D

[NERDfirst]

Hello again!

I'm afraid writing a 3D engine is no trivial task. The code is extremely math heavy and would require a lot of components. I tried it once back then when I coded for Palm OS, nearly drove me to tears =P

I don't know anywhere near enough yet to shoot a proper guide. Perhaps a good way into the future, I could attempt it. As for you, I would recommend you look for a pre-made library, especially if you just want to do 3D graphics.

Fail, I just found a mistake in a comment. I wrote "I'm pretty possible it's going to be slow.", I meant to write "I'm pretty POSITIVE it is going to be slow." Must be that dang autocorrect! xD
