* Shader caching improvementsMiikka Heikkinen2020-02-251-2/+1
| | | | | | | | | | | | | | | | | | Added shader cache load error generation to some cases where it was missing. Properly pass the error to surface viewer. If there was a cache load error, allow exporting the generated cache. Added overloads to generate shader cache with specified compression level.

* Support RGBE hdr images directlyAntti Määttä2019-12-133-179/+12
| | | | | | | | | | Do not convert RGBE images to 16-bit floating point, but use then directly in the shaders. Task-number: QT3DS-4031 Change-Id: Iecfc775247553d5fd8976c77c572435462b79e64 Reviewed-by: Janne Kangas <janne.kangas@qt.io> Reviewed-by: Tomi Korpipää <tomi.korpipaa@qt.io>
* Add env flag for selecting OpenGL backendJere Tuliniemi2019-12-091-26/+35
| | | | | | | | | | | Implementation copied from Quick3D. OpenGL backend can be selected by setting QT3DS_FORCE_OPENGL_BACKEND to 1, 2 or 3. ES2 backend with 1, GL3 backend with 2 and GL4 backend with 3.

* Indicate effect shader errors in Editorv2.5.0-beta2Janne Kangas2019-09-302-10/+19
| | | | | | | | | | | | Show a pop-up if a shader fails to compile. Compilation takes place when the effect is added to a object in timeline. Requires both editor and runtime commits.

* Fix crash when using wrong vertex layout in custom shadersJere Tuliniemi2019-09-232-2/+6
| | | | | | | | | | The shader handle was cached before error checking, so the error checking would be skipped after the first failure.

* Implement two-pass rendering for transparent objectsAntti Määttä2019-09-126-13/+13
| | | | | | | | | | | | | | If object has both opaque parts and transparent parts it will be rendered incorrectly due to no z-buffering. Add two-pass method to render the opaque and transparent parts separately. - Add opaque pixel check to transparency check of images. - Add alpha test rendering to default material shadows too.

* Implement shader cachingMiikka Heikkinen2019-09-1211-45/+163
| | | | | | | | | | | | Currently loaded shaders can now cached with an API call in either source code or binary format. It is necessary to do it that way as the shader cache can only be created in the target hardware.
