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
