digitalmars.D.announce - another d demoscene entry

Hi,

We won another demo compo with a D entry (at MAIN demoparty)
http://www.pouet.net/prod.php?which=53942

We tried to make a bigger and more impressive entry this time. Note that it's a
french party so it's not Breakpoint.

D clearly allowed us to be more productive without a demotool. Still, mature
demotools are one order of magnitude more productive (and awfully long to
make). To be honest i don't expect demosceners to switch so easily from C++ but
it could encourage some newcomers (like us) with a small code base.

I just released the source (again under WTFPL).

Congrats! You're on a roll! I've just watched the demo (works 
beautifully of my GTX260 on Win7) and damn... this is some trippy s**t 
:D The final touch with quickly going backwards was particularly 
jaw-dropping.

Great job, guys. Keep it up!

Loved it, ran smoothly in 1920x1200 on my laptop! That was some trippy 
graphics, very nice shader effects too, and the animations were so 
fluid. It made me remember my college days.. :D

I'm definitely gonna dig into the source, the code doesn't look too 
complex from the few files I read so far and I might learn a few things.

How about a Beatles medley demo next time?

In any ways, great job!

I only get a black screen, but with music.  Can't see any errors in the 
log.  I've got a Radeon mobility hd 3650. Is my gfx card no up to it?

That's what happens when you cross AMD/ATI with OpenGL.

Strange, my first steps in OpenGL years ago were on my 'old' 1950xtx, I 
never had any issues with ATI and GL.

It's most likely an issue in the code than the card, like trying to use 
an extension not present in the driver (the function pointers to that 
extension are then null).

The hardware is fine, since AMD/ATI works fine in D3D. It's their OpenGL 
implementation that smells. It's been slowly improving over the last few 
years (from the state of unworkable to barely OK), but they're still far 
behind NVidia.

We've a whole range of strange bugs on ATI... It _should_ work but there must
be an oddity somewhere in my code.

Could you please test if the debug version tells more ? Thanks !

Ok, you need at least OpenGL 2.0. For example by updating your drivers.

The only suspicious thing in the log is this, which appears twice:

---
Fragment shader was successfully compiled to run on hardware.
Fragment shader(s) linked, vertex shader(s) linked.
  Validation failed - samplers of different types are bound to the same 
texture image unit.
---


Doesn't look that bad, though.  I'll try updating the driver and see.

I updated to the latest driver now, using Mobility Modder.NET to get the 
latest desktop driver to install on my Acer laptop.  Now I get the 
picture of the girl, then it just hangs after that, and Windows pops up 
a message about atikmdag driver having a problem.  Looks like the driver 
crashes or something...

The last line in the log is this:


Demo.createTextureAndFBOs()



So it appears to hang in that function.  The release and debug builds 
seem to behave exactly the same.

You most probably don't have enough video memory available. How much do  
you have installed?

Same here. Do you also use an intel x3100 graphics card?

The demo is unlikely to work on Intel GMA's because it requires more than 128
mb of VRAM (i don't know the state of intel GMA OpenGL support either)

Same exact results.

It's been forever since I cared about graphics cards, so I had too look up 
what I have (although I knew it was either ATI or NVidia). Device manager's 
reporting "Radeon 9200 series" (ATI, of coruse). I have no idea how much RAM 
that has. It does have TV-out, if that helps...

Same for me.  It just crashes while loading.  The debug version is more
informative.  It says:

Error: CompileError : Cannot compile data/shaders/glow.fs
LOG :

These three lines are not in log.txt, but everything else is.  The

Hey, thanks :) !
Indeed there is an error.
uniform sampler1D tex;

gl_FragColor = gl_Color * vec4(1.0,1.0,1.0, texture1D(tex, a));

should be replaced by: 

gl_FragColor = gl_Color * vec4(1.0,1.0,1.0, texture1D(tex, a).x);
