i want that game back!  it owned on the vectrex :p

ABout your work, it works fine here, including the glow effect

Did you have a vectrex Druid?
If you could find a Vectrex on Ebay I think that the Minestorm game was built into the machine.

I had one.  It rocked!  It's now gone, my mother thought it was useless to keep it.  At that age, I wasn't fighting my parents yet....what a fool I was

And yes, that was the game provided..very very adictive!

Hey Rel,

Works great here, AMD athlon64 3500+, RADEON X800PRO 256mb

A very cool effect - works great on my laptop and it is only a NVidia GFX Go5700!!!!
What is it coded in?

I think it's probably Freebasic Drew.

[relsoft]

Yep Freebasic + OpenGL.

Speaking of which I am going to have to brush up on that before long I think Probably I'll be looking at your tutorials first Rel.

Looks great Rel!  The glow effects work here too.

How are you doing this effect?

[relsoft]

1 . Render to texture
2.  Download the frame to system memory
3.  Filter alpha and smooth
4.  rescale and blit over the actual buffer using GL_ADD

You might save on the blur by rendering to texture in a small screen size first, then rendering scene to normal size window, then rendering with GL_ADD. The hardware should nicely blur for you.

err, that's what I'm doing.  Texsize = 64 by 64 on a 640 by 480 screen.
