3d programming with PB

[Comtois]

Hello guys

The only things I would like to do, are:

1. Possibility to export 3D models from Milkshape ( or 3DSMAX 9), or whatsoever..., anyway both animated models and like game levels (not animated.

there are some tools here

2. Possibility to load these into PureBasic with some easy way.

see entity.pb example on your folder.

3. Resize & reposition & move these models inside PureBasic.

Use ResizeEntity(), EntityLocate() & MoveEntity()

3. Move the Camera with mouse (like walk through a room...)

Have a look at terrain.pb example.

4. Use collisions to avoid walking through walls etc,

Have a look at SimpleCollision.pb in this archiv

Hello guys

Actually I did not get an answer to my question, what would be the right way to go....

Depends how much you already know of the matter

Theres several ways going to Rome or to 3D for that matter. Some are simpler to use but somewhat limited by the simple functionality. While others use advanced techniques and are hard to learn but produce state-of-the-art results.

Crossplatform development is also a point.

From your points its possible with almost all available engines so far with PB:
- Ogre Buildin
- Irrlicht
- PureGDK
- DM3D

Of course there are several differences.
Ogre uses .mesh format ( can be exported by milkshape )
- irrlicht can read several formats
- GDK can use X and BB objects ( correct me if i am wrong>! )

Theres also some examples around - well not as many as some people would wish but heck

Just keep in mind that developing 3d stuff can be pretty nerverobbing at times ( especially if the bug your facing is in the underlying drivers of the customers gfx card or something =P ) - just dont give up! Its also rewarding in terms of fun once you get the hang of it !

Cheers,

Yep, thanks.

At the moment I'm doing all my 3D projects using Blitz3D, which is easy, but I'd like to do similar projects (not so compicated) with PB, so what would you recommend me to start with?

Hi,

i am working on an own 3D_Engine for Purebasic and send this little program to this forum, but got no answer. I think the interest here is zero...

Most of the procedures are like Blitzbasic ( i love this program).
In my Engine i have over 100 commands now like

MP_PositionEntity (Entity.l,x.f,y.f,z.f) ; Entity = Mesh
MP_RotateEntity (Entity.l,x.f,y.f,z.f)
MP_EntityX (Entity.l)
MP_EntityScaling (Entity.l,Sx.f,Sy.f,Sz.f )
MP_CountVertices(Entity.l )
MP_VertexX (Entity.l, index.l )
MP_SetVertexX (Entity.l, index.l,x.f )
MP_ImageToTexture(Img.l,direction.b); (use purebasic image as textur)

An exe example of a mesh converter:

Now with a particle engine:

Sourcecode in German forum:

Forcefeedback Joystick

Now i am working on:
Physics (gravity etc.)
sphere collision is ready, but i want to make more collision kinds
procedurale textures/images
landscape
realtime water/moving meshs

I hope i will have in some weeks a alpha version for testing (if somebody wants...)

Hello mpz

I think I did miss something because I cannot understand German language at all, anyway:

DirectXtoMeshKonverter01.exe seems to convert .x models into .pb files, nut unfortunately they created some error messages while trying to run the code. Also there's a small thing, you have to manually add .pb file extension even that the convert format seem's to be *.pb

MP_DX9_PartikelDemo.exe works fine and look's cool

MP_dx9_demo2.exe gives me an error that d3dx9_38.dll was not found ( do have DirectX 9.0c version in my notebook).

So, anyway if you want, I can test it furthermore when ever you update the 3D_Engine or something whatever you want...

But pls. Could you change the comments inside the pb code into English, and also I don't know if there is some English documentation available.

I'm also using B3D, so the syntax of it is familiar for me, the only thing I would need in Blitz3D is possibility to use normal Windows menus, buttons etc... as with PB, and also in PB I like small application size of the exe's

@mpz, I think is interesting a 3D engine for PB... ¿it is coded in Purebasic too?
I am working in a Scene Editor for PB builting commands, but there is no much interest too. So, don't worry about that! When you get a working engine you will be proud.

Hi ekix,

the DirectXtoMeshKonverter01.exe work with Purebasic 4.30 beta 4 fine. I think you have an older version of Purebasic...
I use a newer version of the converter and have added a function for my 3D_engine too to import a Mesh file into the exe file. Now i can make a 3D_engine exe file with diferent Meshs, Textures and music. The size of the program is 50 KB, the picture of the cube has 260 Kbyte. (fine Alpha mode)

I have the d3dx9_38.dll in my Windows\system32 folder:
http://rapidshare.de/files/41012552/D3DX9_38.dll.html
english Forcefeedback file:
http://rapidshare.de/files/41012323/MP_ ... k.exe.html

The complet 3D Engine is written in purebasic and i use Tailbite to create a lib file. I make a help file in german and english too. If i have a alpha version i can send you this for testing...

Here is the Partikle demo with music and 60KByte size. Now i habe 40 KByte free to make a fine Demo for a 100 K contest...

Dear Saboteur,
thanks for your writing. Can you send me a link to your Scene Editor? I never heard about them and i will have a look on it...

Best Michael

Well, I only can say, that the new ogre is great, but for me it's not as good as irrlicht is.
The dreamotion3d hast less graphic-effects but much math-commands.
MPZ-s 3d engine seems to be good, too hehe.. but nothing is impossible.

I needed 1 year to learn dreamotion3d, irrlicht and pb-ogre. So it will take some time to get known to the right engine, but it's fun, when you have got it

here as an advertise: our new free RPG "Magical Twilight" (Gemusoft)
in Progress with Irrlicht (wrapper by Thalius and neotoma)


ps: good engine, mpz.. I must try it out soon hehe
pps: there is an interest in 3d programming in purebasic.. just the ones who are interestet don't want to write comments ;)

and.. there is no really only simple and really good engine good engines seem to be always difficult.
(but the ogre-engine may be the most simple engine at the moment... maybe)

mpz> There's still (and more than ever!) room for a good and simple 3d engine but to evaluate it... We need more examples, demos, code samples! And it's going beyond PB, if it's good enough.
