well, actually, i´m having a complete graphics corruption with these lines
of code
what i´m passing to the wxglcanvas constructor it´s an int
param_gl_canvas[3];
param_gl_canvas[0] = WX_GL_DEPTH_SIZE;
param_gl_canvas[1] = 32;
param_gl_canvas[2] = 0;

Subject: [osg-users] zbuffer precision with osgviewer an wxwidgets
Date: Thu, 28 Jun 2007 16:31:44 +0200
hi, i would like to know how to set my zbuffer precision using wxwidgets
and the new viewer
right now what i´m doing is passing an attrib list to the wxglcanvas
constructor so it´s done in 32bits zbuffer precision.
then comes the osg code with something named traits, and i have something
like this (i took it from the wxwidgets example and modified it a little),
this code is called after the constructor of wxglcanvas
_traits = new GraphicsContext::Traits;
_traits->x = pos.x;
_traits->y = pos.y;
_traits->width = size.x;
_traits->height = size.y;
_traits->depth = 32;
_traits->vsync = false;
setState( new osg::State );
getState()->setGraphicsContext(this);
if (_traits.valid() && _traits->sharedContext)
{
getState()->setContextID(
_traits->sharedContext->getState()->getContextID() );
incrementContextIDUsageCount( getState()->getContextID() );
}
else
{
getState()->setContextID(
osg::GraphicsContext::createNewContextID() );
}
now this is the question --->>> how can i know if i´m having a 32bit
zbuffer now??? do i need to set anything more in order to get a 32bits
zbuffer???
i don´t know if it´s working now cause i still have some zbuffer
corruption, but less than before
thanks in advance and sorry for my english
