Hi,
is it possible to incorporate my own OpenGL preview in the editor? Can I get access to the OGL frame?

I do not think that this is possible, but I will ask the developers if there is a way and get back to you.

According to the developers it's possible to use OpenGL draw functions in any plugin ::Draw() function. Everything (context creation, activate context, swapping buffers) is done by Cinema. The plugin only needs to call the draw functions. Of course you need to first check if OpenGL is activated in CINEMA 4D.

--------- Excuse me. Can you show some example, how to do it. I try write OGL commands inside "::Draw" method of my plugin. But it cause some linking errors. Which libraries should I include? When I include <gl/gl.h> I recieve linking error message:
d:\program files\microsoft visual studio\vc98\include\gl\gl.h(1152) : error C2144: syntax error : missing ';' before type 'void'

I have used direct OpenGL access from ::Draw() function inside my GLSL plugins.
It is only important if you will cnange settings to call glPushAttrib() before do something with OpenGL and then glPopAttrib() after to restore C4D internal OpenGL settings.
I have used glew.h to accees OpenGL.
The only big problem for me was to port it to Mac...
One question, how to proper test if OpenGL is activated?

Hey,
just for reference, you must include windows.h before including the gl headers to get rid of these compiler errors.

I get unresolved external errors for the OpenGL calls I am using.
LNK2019 unresolved external symbol [email protected] referenced in function "public: virtual int __thiscall
The libs (Opengl32.lib,Glu32.lib) and includes (gl.h,glu.h) are however correctly assigned in the compiler settings (and I also checked the OpenGL website which states that this should fix the link errors) and Opengl32.dll is also in the system path.
Does anybody have a clue why it´s not working? Is there a compiler setting I need to add or so?
