c/c++

I starting a program in C++ And I was wondering if you guys could help me on how to use the blitz3d SDK...

I do I have to do?

Best regards

Which compiler do you use?
In the Blitz3DSDK installation folder there are samples showing you how to startup in Dev-C and VisualC compilers

wich samples? I'm going to use microsoft visual c++
I also wanted to know how can I use Blitz3dSdk for Mac. Do I need BlitzMax?
does blitz3dsdk works for mac?

I suppose first you own Blitz3D SDK (update 102) and second you are familiar with the VisualC environment.
In the installation folder of the SDK there is a sub folder 'VisualC'. If you have installed your SDK in hard drive 'C' then the path is:
[C:\Blitz3DSDK_V102\VisualC]
Here you can find the visual C project named: 'applicationdemo.vcproj'
This project is a good start for coding in VisualC.

I never bother my self with the MAC platform so I can't answer to your question

B3DSDK uses DirectX7 so it will not work on Mac.

what about openGL?

What about it? Barnabius just told you that Blitz3D doesn't use it.

you can use SimonHs MiniB3D. It has an additional module for Blitz3D SDK.

This logically means: you must use BlitzMax
But this would allow you to use MiniB3D within Linux / OSX and Blitz3D SDK and MiniB3D on Windows.
