Re: [osg-users] Warning on Add shader to the scene
ah, ok I do remember that thread. And you're saying this is the symptom associated that setting? If so, then the situation is a driver incorrectly reporting invalid value on a valid but unused value. I guess it's not too offensive to compensate by tweaking the unused value to avoid the complaint. Gordon, if that is the issue, could you try changing the ctor initialization value of _geometryVerticesOut from 0 to 1 (src/osg/Program.cpp @ line 99).

Re: [osg-users] Warning on Add shader to the scene
Hi Robert, yes, I saw the specifications and in deed 0 is the default value. I also think that this is a driver bug. However I have the same warning with different driver versions (older and newer one). Maybe the nVidia guys just overseen it. One solution would be just to set this value to 1. I haven't encountered any issues using it like this. Other (maybe more elegant) solution would be not to set this value at all if no geometry shaders are used. However this is not so easy with the current structure of the osg's shader implementation code, I think. It would be cool if somebody could post some comments on this: i.e. if one have this warning and what happens if one change the default value to non zero one ;-) Best regards, Art --- Robert Osfield <[EMAIL PROTECTED]> schrieb: > HI Art, > > Thanks for the explanation.

Re: [osg-users] Warning on Add shader to the scene
HI Art, Thanks for the explanation. Looking at the specs at: http://www.opengl.org/registry/specs/EXT/geometry_shader4.txt It say the default value of GL_GEOMETRY_VERTICES_OUT_EXT is 0, which by convention the OSG normally tried to honour in its own defaults. >From the above text: GEOMETRY_VERTICES_OUT_EXT Z+GetProgramiv 0 max # of output vertices 2.16.4- If this setting is producing a warning then its a bit surprising, might it be a driver bug? If changing to default of 1 fixes the warning then it'd be worth introducing, but... its not the OpenGL default value so we'd need to make a comment why the value is non default. Robert.

Re: [osg-users] Warning on Add shader to the scene
Hi Gordon, here change the line 99 in Program.cpp into this: _geometryVerticesOut(1), _geometryInputType(GL_TRIANGLES), or with other words just set the _geometryVerticesOut to 1 instead of 0. It should be 0 per definition, however this does produce warnings. Changing to 1 doesn't break any functionality and also works fine. If one would like to use the geometry shaders she/he had to change this value in any case. Hence 0, my opinion is, that 0 shouldn't and wouldn't be used at all.

Re: [osg-users] Warning on Add shader to the scene
Hi Gordon, Mike, as I have posted already before (however my patch was not accepted ;-( , this warning comes from the geometry shader implementation. I do not remember the line correctly, but you have to change only one value in the constructor of the Program.cpp There is one geometry shader value is set to 0, I think the number of output premitives. I know this is the specification, however if you do not use the geom shaders this does produce the warning. Just a change to any positive value do remove the warning and do not produce any errors during the rendering.
