Im going to have a bash at a rasterization wire-frame 3D engine also this year - can make apps like Elite and such like.

It will be based on 2D physics boosted to 3D worlds.

Will include own OBJs too and getting the geometries correct.

I looked at this been useful on the Mine-craft thread - but this beast is in its league of its own.

It will be based upon this guy

I know, I know. But who didnt love Elite or similar

This will have functions available to you for doing your own Scaling / Transforms (movements) / Translates (rotations) - I know AppGameKit does this for you - but thats with AGKs own Objects.

Im talking about 2D to 3D wireframe games

and also 4D / 5D / 6D transformation matrices too, so will help you develop games in those

Looking forward to it...

I was reading a rather long tutorial,

I am interested on how such a system performs

Thanks.. I just meant it will take a few months to put together x got other projects on at mo

But I certainly like to try this one

So your posting on an AppGameKit forum......about trying to make a completely seperate graphics engine?

I also follow that guy on the tube..
would be cool to make a wireframe fps

Yes and No - getting some ideas on how to create Elite / No Man Sky type of games all done with using Drawline commands.

But the workings out / gemotories / rotations / transforms etc will need to be manually created.

Is this something that I shouldn't be doing?

It's not for me or anyone else (except maybe the mods, obviosuly) to say what you shouldn't be doing, it just struck me as ironic. Lol.

Wireframe 3D modeler ?
Heh ! It remind me 20 years ago, when for my Baccalaureat diploma I created a 3D Wireframe modeler under Turbo Pascal :p

Hee hee - well done too.

I got to college BTEC Diploma and did Distinctions (A*) in all my programming courses - went to Uni and found a girlfreind - and failed uni - all went down hill from then on lol

Well done to you both

I got Distinctions in I.T during college too and then did very well at computer science at Uni but the fact I never got a girlfriend
might've helped Mind you towards the end of my degree met a lovely girl through a dating App that was head of the IT
department managing computer systems for many doctor surgeries. hahah well it never lasted completed my degree
and still great friends with the lady I met.

Mind you my high school days grades were not so good hence why I went to college then university

It's *always* those women distracting men, started with Eve already.

Heard many of these kind of stories over the years causing education/life goin to s*. lol

I will save you my horror stories but, yes, costed my education too.

(If any women here reading this, please notice the "wink-not-too-seriously" tone, it's just us men who are the weaker species.. )

Nice little story there. I'm sure there is someone out there for everyone. Just haven't found yet. Probably never but that doesn't upset me cause I can crack on at making games for life without no distractions

Swiftly moving on lol x

Thinking -

Load an object - any object and join each vertex with a drawline in 3D (not drawing the shared vertexes)

Thats a wireframe.

Job Done!!!

Next!!!! lol

You can even do it without loading any object...just with arrays of imaginary vertex an then drawing line from one point to the next...

Edit. Just start with an easy primitive...something like a box.

Edit.
I'm going to try with a funy one....you are not alone

This is a very good idea to learn.

Heavy spoiler Alert !
I made a 3D Renderer some years ago
You can fly with the camera, there is counterclockwise face drawing code and a bit to load indexed and non indexed models.
Doesn't work 100% but it was nice to learn it at the time.
And I encourage you too, to make you own version first

@janbo That is great ,thanks for sharing . We "programmers" are all the time trying to reinvent the wheel ...perhaps not to get bored....this is the best way to learn .

Thanks Janbo - yes thats what i thought too. I started on a 4D wireframe tesseract long time ago and it was so much fun working out the maths..

and will be a great learning curve to many - especially for the beginners coming into 3D, like meee

Thanks for the link - I will check it out later
