Playbasic is meant to make 2d programming easy, not 3d!
Why are there some 3d demos? I'm confused? Does this mean
that you lied ....sob...sob....
oh, on the brightside, yay 3d!

It's amazing you're reading this, surprise... you still are.

It has no 3D commands or features at all (well, not yet anyway). What you think is "3D" is just some clever (old-skool) 2D effects, the same way the original Wolfenstein/Doom games worked before 3D cards came along.

A great many people think they are thinking when they are really rearranging their prejudices.

It sounds amazing but how the hell does it work, unless the people who created that w3d demo spent months doing every single tiny detail! Either way, they probably didn't do that, I can learn how to do those 3d-style effects myself and completely ditch DarkBasic!

You're forgetting something... namely that these proticular old-school effects require a engine with approx. 4-5 times the complexity of dbp. you have to:

make sprites of EVERY OBJECT from (virtually) every angle. 8 angles to be precise, then multiply that by 3 (one for viewing from below, one for viewing at the same height, and one for viewing from above)

That's 24 sprites * number of moving objects.

DBP, all you do is "load object obj,file$" "position object obj,x,y,z," and you're set. a) it looks a lot nicer, because of that you can view it from 360x360 directions b) because it's actually a 3d scene and doesn't look like doom (doom 1, that is, not doom 3 moron )

Hawkeye that isnt correct... I think the wolf 3D demo uses a mode 8 effect... Can anyone back this up?

Im pretty sure it does though...

Totally 2D.

The Wolf demo and UW3d demo are 100% software renders.

The wolf demo is simple linear texture mapping. While wolf (the original) was done using ray casting, this demo exploits the same cheat, but manually projects and renders the visible walls strips.

Hawkeye - That's not how the oldschool 3D engines were made. They used real 3D engines, but were software driven only. There was of course a lot of math involved (much more than would be required nowadays), but they didn't need to take sprites of every single texture at every angle.

I remember I had to do a 3D wireframe model in C++ back in '95, before any hardware acceleration was feasible. It was tough, but doable.

I actually have a book from 1994 titled:

Programming with C/C++ - 3d visualiztion, simulation, and virtual reality.

A few of the examples in the back go through creating a Wireframe ship... quite a long appendix to say the least. No doubt its a pain in the ass heh

LEEEEEEEEEEEEEEEEEROY JENKINS!!

hmmrm.. well never mind then Could've sworn that there was a method called 2.5d that did something like this, but eesh I dunno.

Quite a few games used that method you described, but as Jeku said, its different.
