EDIT: nevermind


My software never has bugs, it just develops random features.

Firstly is there a reason you have to use the binary version of stl as I'm sure you could do it yourself if you can convince your client to use ASCII stl files.

Secondly this is the third thread you've started for the same subject. This will just get annoying as it is considered spamming. Just stick with one thread and people will see the full history of your problem and hopefully a resolution.

Did you try the code from this thread? http://forum.thegamecreators.com/?m=forum_view&t=12043&b=1

So did you try that code? It looks pretty close to me but I can't test it at the moment as I'm at work.

I actually work as a CAD software developer and might be able to help if I can find the time to learn a little more about STL files etc.

You don't need a plugin just the code to import / export simple STL files right?

You have been given links but not commented on whether they worked, did they?

If I can load your object I'll give you the code for free. Most people who can help here will do so for free.

Thanks baxslash, you're a real valued member.

I tried the recommended code long ago but didn't work because the binary file seems to be sort of new type of binary. so, it was difficult to understand the format. I worked on the recommended code before your advice but no chance.
however, as well I couldn't get my client to change his mind for reasons that I understand very well.

I know c++ very well but I don't know OpenGL otherwise the problem may have been simpler.

I contacted the support team and they said that I can only solve the problem using c++ (something that I already figured out.)

Could you post their explanation as it might help to solve it?

I'm learning about stl to try and help you out so I'll keep you posted.

A quick update:
I have just loaded part of your model you posted in the other thread. The problem seems to be that using the method in the link I gave you loading slows down dramatically after the first 1200 or so polys. There are around 9800 polys in that model which is going to maybe never load. I'm going to try another method and get back to you.

this was the support team answer:
I am sorry we have no support for autocad or STL files. You will need to write a plugin for DarkBASIC Professional that allows loading of this file standard. However this must be done in C++ if you do not understand C++ then this will not be possible for you.

Wrong!!!

Attached is a project that will load stl files in the format you provided using some only slightly modified code from that provided by @RapidTools in the link I posted.

Not sure if it will fully satisfy your requirements but let me know if it needs tweaking ;P

EDIT: Here's an image. By the way we could easily speed up loading times if needed by not using "sync" in the "LoadSTL" function.


This function will ONLY load the binary type STL such as you provided and does not check for ASCII format files.

Amazing!!!!!!!!!!!, it was loaded within a second. I read your code and I can't believe that the dummy bytes has caused me all this mess. however, tomorrow I will sit on the code and try different files. as well need to discover how did you know the EOF (end of file), anyway that is simple.

many thanks baxslash

Yes very simple, the value of 'f' is the number of polys.

Glad to help
