Hi,
Texture compilation ==
Code:
Texture2D::apply(...)
{
texture object -> bind
Texture::applyTexImage2D_load(...)
{
pbo->bind
glTexImage(. . ., image offset in buffer object)
if (pbo->getCopyDataAndReleaseGLBufferObject())
{
pbo->unbind()
pbo->releaseGLObject()
}
}
if (unref image data after apply)
{
_image = 0;
}
}
The GL buffer object is released before the image is unreferenced.
In order to release the GL buffer object implicitly when the reference count of
the OSG buffer object reach 0, the member "CopyDataAndReleaseGLBufferObject"
has to be false.
The user may not want this behaviour. It can be a parameter of the pager (like
"assignPBOToImages").
Thank you!
Cheers,
Lionel
