I've been working on porting a Qt4 GL application to Qt5, using the new QOpenGL classes instead of the old and deprecated QGL classes.
Some of it was really easy. Some of it is requiring MASSIVE amounts of work. I refer specifically to the removal of the text rendering methods. Since these are removed, what is the easiest way to go about drawing non-scaled, billboarded text in a GL scene? (Note: I am on Qt 5.4 at present; no Qt3D.) If I go the route of pre-rendering the text into a QImage, what is the easiest way, using only the modern QOpenGL classes (since there is no longer bindTexture either), to get that into an OpenGL texture? Actually using this stuff in anger, I am finding myself less than convinced that the new class is an improvement... implicit context sharing is nice, but the loss of convenience methods is really, really painful. (And I'll include qgl[Clear]Color in that list...) -- Matthew _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
