| | | | | | | | These are useful for performing ray marching in the fragment shader and for mapping from screenspace or NDC to world space in general. Change-Id: I1f273f16c85cdf6c46c03a63f80a6202305c7eaa Reviewed-by: Paul Lemire <paul.lemire@kdab.com>
* ClearsBuffers: make the RenderViews store clearbuffers valuesPaul Lemire2016-07-041-4/+13
| | | | | | | | | | This then allows to only do value lookup at submission time rather than accessing the backend node. This will be a great help when submission and frame processing are later on parallelized.

| | | | | | | | | | | | This avoids doing not necessary lookups to retrieve the id and will later allow to be sure that we are relying on data that is not going to change if the submission and frame processing are made in parallel.

* Fix race with UniformBlockBuilderPaul Lemire2016-07-041-1/+2
| | | | | | | | | Since there can be n jobs executed in parallel for a RenderView, the UniformBlockBuilder needs to be unique on a per thread basic and not on a RenderView one like it used to be. Change-Id: I4495a8474753f41c7a99d50056eb1fbf968ef5d4 Reviewed-by: Paul Lemire <paul.lemire@kdab.com>
* Further job improvementsPaul Lemire2016-07-041-5/+12
| | | | | | | | | | | | | | The RenderViewInitialization job used to have to wait for the world transform job to be completed because it was used to set the viewProjectionMatrix. This patch adjust dependencies and adds a new job that sets the viewProjectionMatrix once the transform update job is complete. This allows to start most of the processing earlier and better use the available cpu cores. Change-Id: I77d751e0b20639934cc00be0cd9888f41f684f89 Reviewed-by: Paul Lemire <paul.lemire@kdab.com>

* Lights phase 1: infrastructureLaszlo Agocs2015-11-261-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | QAbstractLight becomes QLight and gets its own backend node. This way we can easily gather all lights for the scene and filter them when building render commands. Both the frontend and backend remain a subclass of (Q)ShaderData but will not be part of the ordinary ShaderData component list. This prevents mixing up ShaderDatas and Lights but allows reusing the same underlying infrastructure so that properties can automatically be transformed for example. It is worth noting that the position property for lights is now removed: the position is determined by the entity's (to which the light component belongs) position. A number of changes are made to ShaderData itself as backend subclassing with different managers is not straightforward. For now the distance between the rendered entity and the entity with the light component is calculated and lights will be chosen based on this distance. A framegraph node for controlling this will be added in future patches. No uniform setting or shader changes are included here.
