Basic 3D Shape Commands?

Yerrel · Post by **Yerrel** » Sat Sep 25, 2004 4:21 pm

Hoi there again,

After experimenting with PureBASIC, reading the manual etc.., i have a very very important question and that is:

Is there any 3D command for making a cube or cone or triangle or other basic 3D-shapes?
If not, how do i accomplish this? like creating a Cube, Triangle, Cone, sphere and so on.

Please help me! coz i need some serious help here..

Tnx for you help..

The current implementation of OGRE doesn't support making primitives in PB.

Okay!

than can you give me a example-code or any Purebasic tutorial link that i can learn from on how to make Primitives plz..

tnx

the simplest method that I have used is to just do them
in MS3D and export as .mesh. Then just rescale them in code.
If you do a search for a desired shape, I think there is code
for creating shapes 1 polygon at a time. I'm sure I saw one for
spheres, cubes and planes are simple to construct.

edit:
Well, I did a search and the best I came up with was this...
viewtopic.php?t=10893

It shows how to load an MS3D ascii file. From this,
you should be able to see how vertexes are aranged and
polygons connected.

Hi Yerrel

This can hopefully help you somewhat...

My docs are not in the best of states, but there is a example that is quite explaining, would be very interested in feedback.

Hoi Erlend,

It must be great if it only could work.

But nothing happens when i run it!
Worse, i get the following error:

Line 25: QVertex() is not a function, an array or a linked list.

Is it something that i have to do? like putting the required library somewhere? or need to Dload the needed Library?

Hope u can correct or guide me with this problem...

tnx,
Yerrel

You have to put the QMesh lib (in the archive)
into purelibraries\userlibraries...

Done that and the examples do execute.

But i still don't understand it at all..

... Cozx i am a real beginner @ PureBASIC ( programming ).

Coz i am looking for something like Createcube() or like Make Cube).
Your library seems to be okay if u could only type just a little documention about how to use it etc...

....

Example. Here I use only QCube()(create a cube..). Don't ask me what else the
librarys does, I don't use it...

This is a result of 2 minutes of reading through the code..

Okay thanks Olejr  :wink: 

Bcoz of work i can't hardly find time to do some heavy reading or xperimenting.. But time will come to dig into PureBASIC..

Diz code is clear as dunnow what  :D 

Now i understand the Qmesh Lib...

tanx 2 all
