Hi Eric and Andre,
I have just do a cvs log on PointSprite.cpp:
revision 1.9
date: 2006/11/14 12:29:54; author: robert; state: Exp; lines: +18 -5
From Farshid Lashkari, "This patch adds a CoordOriginMode to the
osg::PointSprite attribute.
The mode needs to be changed to LOWER_LEFT when rendering point
sprites to pbuffers or FBOs, otherwise the points will be transformed
on the CPU."
The new lines are:
if (extensions->isPointParametersSupported())
extensions->glPointParameteri(GL_POINT_SPRITE_COORD_ORIGIN,_coordOriginMode);
So I'd suspect these as being problematic. It'd be worth checking if
GL_POINT_SPRITE_COORD_ORIGIN is supported, if not then we probably
need two isPointParametersSupported() methods in the
PointSprite::Extensions object.
Robert.

Hi Robert,
I got the warning too. Here is a dump from OpenGL Profiler:

It looks like the extension "GL_ARB_point_sprite" is not available. Very
strange. I am running on a PowerMac G5 with ATI X800XT and CVS version of
OSG.

I started playing with the osgpointsprite example today (did an update
from CVS). I am seeing a lot of these messages:
Warning: detected OpenGL error 'invalid enumerant' after RenderBin::draw(,)
I don't see any of these warnings in the stable osg 1.2 release.
Any ideas?
I have just run osgpointsprite and its working fine under Linux/NVidia
drivers.
Could you provide a dump of the OpenGL version/extensions supported on
your machine?
Robet.
