* Implement a special case, simplified vertex shader for complex geometryEskil Abrahamsen Blomfeldt2010-03-161-0/+12
| | | | | | | | | | When drawing text, the vertex count will most likely be so high that using a uniform-based, simpler vertex shader is faster. We implement the ability to inform the shader manager that the geometry is considered complex, so that it can choose the simpler vertex shader in these cases. Task-number: QT-2887 Reviewed-by: tom
* Use an attribute value for the PMV matrix rather than a uniformTom Cooksey2010-01-211-1/+4
| | | | | | | | | | | | | | 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

* | Track which vertex attrib arrays are enabled in QGLContextPrivateTom Cooksey2009-12-301-0/+3
|/ | | | | | | | | | | | | The GL2 engine (and probably Qt/3D) needs to track which vertex attribute arrays are currently enabled and which are disabled. As this is per-context state, the logical place to track this is in the context and not in the paint engine. This patch also makes the GL2 engine's shader manager enable/disable the appropriate attribute arrays for a given shader program when it is used. Reviewed-By: Kim

* Implement a simple caching algorithm for shader programs.Tom Cooksey2009-10-301-2/+11
| | | | | | | | | | When the number of programs held in the cache exceeds a threshold, the least frequantly used programs get deleted. This also covers programs with custom snippets of code. As a conequence, when a QGLCustomShaderStage gets deleted, any programs using that code will (eventually) be freed. Reviewed-By: Samuel Rødal

* Refactor of shader manager to not use partial shadersTom Cooksey2009-10-301-32/+32
| | | | | | | | | This is a first step towards supporting binary shaders. Note: This change will introduce a (rare) leak of shader objects, as the shaders will never be kicked out from the cache (because the cache is still a QList) :-) This will be corrected by the next patch. Reviewed-By: Samuel

* Fixed glsl warnings on mac and stop using texturecoords when not neededGunnar Sletta2009-09-161-2/+0
| | | | | | | | | | The setTextureCoordsEnabled was enabled in two places, but never disabled causing it to always be used. When using a varying in a vertex shader and not using it again in the fragment shader this produces a warning, and rightly so. Since the property is 100% detectable based on the fragment shader used, move the logic into the shader selection code and kill the property all together. This should also speed up solid filling a bit...

* | Fixed GL2 engine shader manager to work with more than one context.Kim Motoyoshi Kalland2009-07-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I added a QGLContextResource class which can be used internally in Qt for sharing resources between contexts. The QGLContextResource is a hash map where the context is used as 'key', and the resource is the 'value'. All the sharing contexts point to the same resource, and the resource is automatically deleted when it is not referenced any more. Now, the shader manager uses the QGLContextResource class. I also added a pointer to a struct in the QGLContextPrivate class. The struct is shared between all the sharing contexts and is deleted automatically. Currently, the struct only contains the resolved OpenGL function pointers. The shared context register code has been simplified. Reviewed-by: Tom
