RTG screen dragging?

Hi

I have just tested the AROS Vision 68k distro, using WinUAE. It works fine, but not as smooth as the original yet

But RTG screen dragging works, and can that be applied to Amiga OS? Where is screen dragging hidden? The Picasso96 drivers or in the kernel?

I would be fantastic if we could port RTG screen dragging from AROS sources back to AmigaOS! Something like an enhanced Aros for Amiga

Is this doable?

Same old answer: AmigaOS RTG subsystems are closed source, it is impossible to add major feature like screen dragging.

AROS can do it because its graphics subsystem is created from scratch.

You can already do RTG screen dragging on real Amiga and Amiga OS, if you use CGX instead of P96. But I guess there's no way to add support for CGX with WinUAE...

Thanks for the replies, guys.

But I was thinking, could AROS sources replace the Picasso96 drivers? Imagine WinUAE with DirectX.hidd....

I mean, when WinUAE and AROS has come this far, how come we must use close sourced graphic drivers more then 10 years old?

Could Gallium 3D be used in an emulated environment?

I don't think it's a question of the graphics card driver, rather than the whole RTG system. Any RTG system will have to make pretty extensive changes/patches to many intuition.library and graphics.library functions. So someone would need to write an open source RTG system first. The existing AROS code doesn't address that patching process.

As jPV said, CyberGraphX does support draggable screens. I don't know whether it would be possible for someone to write a CyberGraphX driver for WinUAE or not. As far as I recall, the RTG system developers (both CyberGraphX and Picasso96) never made documentation on how to write graphics card drivers publically available.

It is not perfect but this can already be done with Dragon:

Exactly, CyberGraphX _driver_ development documentation is hidden in someone's safe.
