* Workaround for ATI driver bug when using QGraphicsEffect with GL.Kim Motoyoshi Kalland2010-05-122-5/+6
| | | | | | | | | If you forward declare a shader function which takes a sampler as argument, the shader program will fail to link on ATI cards under Windows. Task-number: QTBUG-10510 Reviewed-by: Trond
* Fixed QGLPixmapDropShadowFilter on Nvidia hardware.Trond Kjernaasen2010-05-111-4/+5
| | | | | | | | There seems to be a driver bug that causes glTexSubImage2D() to not align data correctly when uploading a GL_ALPHA texture. Task-number: related to QTBUG-10510 Reviewed-by: Samuel
* Fixed an issue with pixmaps not being released correctly in the GL 1 engine.Trond Kjernåsen2010-05-101-0/+5
| | | | | | | | | | When a pixmap is bound using the texture_from_pixmap extension we retain a reference to the pixmap to stop us destroying it before swapBuffers() or glFlush() is called. The references were not cleared out correctly in the GL 1 engine. Task-number: QTBUG-10529 Reviewed-by: Samuel

| | | | | | | | | In the case where a polygon or polyline that contains consequtive equal points, we end up calculating an invalid normal vector for the joins. This fix skips past duplicate consequtive points. Task-number: QTBUG-9548 Reviewed-by: Kim
* Fixed caching of QPainter patterns in the GL 2 engine.Trond Kjernåsen2010-04-071-1/+1
| | | | | | | The patterns all got the same cache key (e.g. 1), which caused the patterns to be uploaded as a texture every single time they were used. Reviewed-by: Kim

* Worked around driver bug causing clipping errors on N900.Samuel Rødal2010-03-101-3/+8
| | | | | | | | | Apparently the driver does some optimization which causes it to behave erratically when stencil testing is enabled. Multiplying the return value from the texture lookup by 1.0 disables the optimization. Task-number: QTBUG-8753 Reviewed-by: Trond

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the user provided their own shader with glShaderBinary(), QGLShaderProgram::addShader() would refuse to add it because it wasn't marked as "compiled". According to the OpenGL/ES 2.0 specification: "It is permissible to attach a shader object to a program object before source code has been loaded into the shader object or before the shader object has been compiled." Based on this, the compile check has been removed from addShader() which should make supporting binary shaders easier. Similarly, link() and programId() have been modified to support applications that use glProgramBinaryOES() to specify program binaries. Task-number: QTBUG-7490 Reviewed-by: Tom Cooksey

|/ / | | | | | | | | | | | | | | | | | | | | | | There is a lot of code depending on that pixmaps are flipped upside down in the gl graphicssystem, so toggling this requires extensive testing. Since we're anyway questioning the relevance of this feature (compared to raster + GL viewport) its simply not worth the effort to fix it properly right now. Revert "Fixed y-inverted pixmaps on N900." This reverts commit 57473d5d2a7bd6ae3117f61ff29264a1b790bb01.

* | Use an attribute value for the PMV matrix rather than a uniformTom Cooksey2010-01-215-31/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This has several advantages: First, updating an attribute value seems to be cheaper than updating a uniform. Second, vertex atribute values are independent of shader program, which means they persist across changing of the shader program. This makes code simpler and reduces GL state changes. Note: Credit goes to Samuel for finding this little gem. :-) For the 25920 solid QGraphicsRectItem test case, this gives 10% improvement on desktop and 27% on the SGX. Reviewed-By: Kim

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Qt used to store the GL extensions a particular implementation supported in a global cache, which was initialized once and never updated. This could cause problems because different types of context might support different kinds of extensions (e.g. the difference between sw and hw contexts). With this patch, the GL extensions are cached and updated within each QGLContext. It also makes the extension initialization lazy, which saves application initialization costs for embedded platforms. The patch introduces a internal cross platform QGLTemporaryContext class that is used to create a light-weight GL context without going via QGLWidget and friends (QWS and WinCE still have QGLWidget fallbacks for now).
