* Long live QOpenGLDebug!Giuseppe D'Angelo2013-03-151-2/+4
| | | | | | | | | | | Qt convenience classes for the GL_KHR_debug extension This allows the developer to 1) ask the GL for a log of the last generated messages; 2) emit Qt signals whenever the GL wants to tell us something.

* Add QOpenGLTimerQuery and QOpenGLTimeMonitor classesSean Harmer2013-03-121-3/+5
| | | | | | | | | | | | | QOpenGLTimerQuery encapsulates a single OpenGL timer query object. QOpenGLTimeMonitor is a convenience wrapper around a sequence of OpenGL timer query objects that can be used to profile OpenGL rendering code or to allow real-time adaptation of rendering methods based upon run-time performance.

* OpenGL: Add QOpenGLVertexArrayObject classSean Harmer2013-02-281-2/+4
| | | | | | | | | | This class makes it much simpler to manage OpenGL state relating to vertex data (i.e. vertex buffer objects, vertex attribute divisors, index buffer objects, vertex buffer formats).

* OpenGL: Add a set of version and context specific OpenGL classesSean Harmer2013-02-261-2/+60
| | | | | | | | | | | | | | | | | | This commit adds part of the output of utils/glgen and some simple modifications to QOpenGLContext to allow easy access to classes containing functions specific to a given OpenGL context and version. This allows compile-time detection of mis-use of OpenGL features. For example, trying to use glBegin(GL_TRIANGLES) with an OpenGL 3.2 Core Profile context will be detected by the compiler rather than at runtime. These capabilities make it much easier to add functionality to Qt and applications that relies upon core features of OpenGL from specific versions e.g. geometry shaders.

The ifdef QT_NO_OPENGL in the opengl headers are needed, as qmake adds depends in the makefiles for all GUI headers.

* Implemented texture cache for GL paint engine in QtGui.Samuel Rødal2011-09-121-0/+2
| | | | | | | | | | | This is simpler than the existing texture cache in QtOpenGL, as it only serves the GL paint engine. There's one per context group, to simplify the design and to prevent performance degradations.
