Re: [osg-users] osgpointsprite: Warning: detected OpenGL error 'invalid enumerant' after RenderBin::draw(, )

Hi Robert,
GL_POINT_SPRITE_COORD_ORIGIN is not part of the GL_ARB_point_parameters extension. So it is not enaugh to check for this extension. GL_POINT_SPRITE_COORD_ORIGIN is a OpenGL 2.0 feature, which is currently not available on a Mac. On my linux box I have GL >= 2.0 and seeing no problems with 
osgpointsprite. We need something like:

if (extensions->getGLVersion() >= 2.0)
extensions->glPointParameteri (GL_POINT_SPRITE_COORD_ORIGIN,_coordOriginMode);
GL_ARB_point_sprite and GL_ARB_point_parameters are both part of OpenGL 2.0

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.

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.

Hi Eric,

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.
