* Make the OpenGL renderer a pluginPaul Lemire2020-02-052-564/+0
| | | | | | | | By default the QRenderAspect will try to load this plugin Change-Id: Ie55e207fb8e6d0b64f717bbb99699eb669eaa3f2 Task-number: QTBUG-61151 Reviewed-by: Mike Krus <mike.krus@kdab.com>
* Introduce a GLShader classPaul Lemire2020-02-031-27/+84
| | | | | | | | | | | | | | | | GLShader is renderer specific shader implementation for OpenGL. Shader now contains only backend information for a QShaderProgram frontend node. - Similar to the GLTexture handling, a generic adopt/abandon manager for shaders was introduced (regardless of the actually GraphicsAPIShader class). - The renderer and renderviews were adapted to the new changes. This was the last major thing preventing the modularisation of the QRenderAspect and renderers Change-Id: If671d60928b433977e9d6e5c58199827f9408a3f Task-number: QTBUG-61151 Reviewed-by: Mike Krus <mike.krus@kdab.com>
* QSortPolicy: add Uniform sorting modePaul Lemire2019-12-201-0/+1
| | | | | | | | | | | | We used to perform uniform minization between adjacent render commands all the time. Since this can yield to a higher CPU usages (but more efficient rendering submission), we now make this step optional. [ChangeLog] QSortPolicy add Uniform mode (to control whether uniform minization should be performed) Change-Id: I5c0e0dba22400a9884ee1d75426fd76b073fdcb5 Reviewed-by: Sean Harmer <sean.harmer@kdab.com>
* PackUniformHash to QVectorPaul Lemire2019-11-141-9/+4
| | | | | | | | | | | | | | | | | | | Surprisingly it's hard to notice its effect in the speed of execution, frame preparation looks to be more or less the same with the profiler. However with vtune, the profiling traces show a huge difference with QHash, mainly in time spent allocating memory. It shows a noticeable reduction in CPU usage. On bigscene-cpp with 600 entities QHash -> On a 158s run, CPU time is 112s (70%) free accounts for 26s (23%), malloc 24s (21%) QVector -> On a 190s run, CPU time is 110s (58%) free accounts for 5s (4.5%), malloc 4.7s (4.2%) Change-Id: I880d44b1acf7f051e479ed356864c3caf407f23f Reviewed-by: Mike Krus <mike.krus@kdab.com>
* Split RenderCommand generation and uniform updatePaul Lemire2019-10-211-65/+61
| | | | | | | | | | | | | | | | In most cases, we can generate the RenderCommands once and reuse them in subsequent frames only updating the uniforms. We still have to copy the RenderCommands as the renderer renders while we start preparing the next frame. This is still faster than regenerating them entirely. Regenerating the entire commands will happen only when FrameGraph or Scene structure changes. That should rarely be happening on a per frame basis. Next step could be to look at how to only update commands for Entity with Parameters that have changed.

* QSortPolicy: add sorting by TexturePaul Lemire2019-03-061-0/+79
| | | | | | | | | | | It can be more efficient to render a scene by sorting drawing commands based on the textures they are requiring. In conjunction with Material sorting, this can reduce the amount of GL calls being sent to the driver. [ChangeLog][Qt3DRender] QSortPolicy can now sort by Texture Change-Id: Ibc013e9d506ea3061b19a56c548e8184f2b981cc Reviewed-by: Mike Krus <mike.krus@kdab.com>
* Fix RenderView uniform minificationPaul Lemire2018-02-281-5/+86
| | | | | | | | | In the case where we had two or more groups of RenderCommands where each group shares a common shader, uniform minification wouldn't be applied to the second command of each groups after the first one.
