JOGL

Postby mkiefte » April 18th, 2008, 6:08 pm

I just ran some JOGL demos in a Windows VM in Linux and it ran surprisingly well. I wanted to see how well JOGL would run on a machine that clearly did not have hardware rendering capabilities. It doesn't look like it's using the real graphics device, but just software rendering. What I don't understand is why ZunTzu is so slow...

"users", not "uses".



Caught that.

Could you send me your mock-up? I'd like to play with it.

Where did you get your documentation for JOGL? Just from the website?

- M.

My understanding of ZunTzu is that it uses DirectX not OpenGL for graphics.
Many computer games using DirectX that are 3d (like Oblivion) suffer horribly if one uses Open GL drivers instead for rendering - may be why its so slow

My understanding is that DirectX and OpenGL are completely incompatible so you can't use one as a substitute for another. Is that incorrect?

That's what I thought, but I might not know.

You might actually be getting the hardware rendering for OpenGL through
your VM. But you won't be getting hardware rendering for DirectX that
way.

That occurred to me after I ran it, but I checked what Windows thought was the video driver and it looked like a pretty basic SVGA device (although the driver was specific to VMWare, so who knows).

I'm poking around to find the slowest, most underpowered computer with the least sophistocated I can get my hands on.

I think the parts for a 486 might still be at my parents' place. :p

Joel, there's something really funky about your demo. Everything about JOGL suggests that it's a thin layer over OpenGL except for the functions init and display which have me confounded. I didn't notice a problem until I tried zooming (I don't have a scroll button). Let me have a go at it while you worry about Mac menus.

Or just run things over VNC. That'll disable any OpenGL acceleration and
probably disable XRender depending on the verions of VNC
