Andy,
yes a (beefy) video card is needed or at least wanted, as you want to
offset the calculations to the GPU. If one isn't present, you're going
to fall back to a software opengl implementation which will be orders
of magnitude slower than what AGG is going to take.
cc-ing Toby if he wants to comment further on this.
regards,

I cannot seem to get opengl to work.
a stacktrace of shp2img:

I'll continue my comments from another thread in this better named thread.
So... I'm confused with mapoglrenderer.cpp.
I dont see where any GLX context or PBuffer have been setup yet before the
first call to OglRenderer::OglRenderer. The first thing it does is:
glGetIntegerv(GL_VIEWPORT ,viewPort);
But how can there be a viewport size yet? I added a debug message right after
it:
if(msGetGlobalDebugLevel() >= MS_DEBUGLEVEL_DEBUG)
{
msDebug("viewport %d, %d, %d, %d\n", viewportX, viewportY,
viewportWidth, viewportHeight);
}
and got:
$ ./shp2img -all_debug 15 -m /pub/maps/test.map -o x.png
[Fri Mar 11 19:30:01 2011].731230 msLoadMap(): 0.000s
[Fri Mar 11 19:30:01 2011].731352 viewport 48, 135483496, 134889737, 0
that cant be right... can it?
The next thing is getTextureSize, which calls glTexImage2D. Will that work
with no context?
