You can look at the files I posted over there:

http://www.leadwerks.com/werkspace/topic/11579-3d-screen-mode-for-3d-glasses/#entry83580

If you open the StereoRender.cpp from the zip-file, you can see, how you can use buffers.

 

Basically that file creates a Buffer called "leftEye" by using:

Buffer* leftEye = Buffer::Create(context->GetWidth() + 1, context->GetHeight(), 1, 1, 0);

 

This buffer can be cleared by

leftEye->Clear()

 

Rendering to this Buffer is done by:

context->Disable();
leftEye->Enable();
world->Render();
leftEye->Disable();
context->Enable();

 

The example then draws the leftEye-image over the context's image by using

int blendModeOld = context->GetBlendMode();
context->SetBlendMode(Blend::Alpha);
context->DrawImage(leftEye->GetColorTexture(), 0, 0, context->GetWidth()+1, context->GetHeight()+1);
context->SetBlendMode(blendModeOld);

For all available methods you should take a look at [LeadwerksInstallDir]/Include/Classes/Buffer.h.

You can easily bring it up by pressing "Ctrl"+"," in Visual Studio and then typing "Buffer".

Oh!

I've didn't know what class drow buffers.

So, it's Context?

I don't really understand the question but I guess it's about the relationship between Context and Buffer.

The Context-class inherits from / extends / is a sub-class of the Buffer-class, so basically the context is a special sort of buffer.
