Known Issues
-The technology preview version is still missing some features entirely, while some
-others may be only partially implemented. Here are some known issues:
-- Scatter graphs can only show zero centered axis ranges properly.
-- Value axis range of a bar graph with negative values need to be zero
- centered to display properly.
-- Selection API is missing for surface graphs.
-- Shadows do not work for surface graphs.
-- Mac: Graphs drawn half the size on Retina displays.
- Using multiple graphs in one application crashes on application shutdown
unless the last graph to have active context is deleted last.
- Android doesn't support both widgets and OpenGL simultaneously, so only
the Qt Quick 2 API is usable in practice in Android.
- Shadows are not supported with OpenGL ES2 (including Angle builds in Windows).
- Anti-aliasing doesn't work with OpenGL ES2 (including Angle builds in Windows).
+- Surfaces with non-straight rows and columns do not always render properly.
+- Wrong item can end up selected if you do mouse selection and data removes/inserts
+ simultaneously due to the asynchronous nature of mouse selection handling.
+- Q3DLight class (and Light3D QML item) are currently not usable for anything.
+- Q3DScene::secondarySubviewOnTop property has currently no effect.
+- The color style Q3DTheme::ColorStyleObjectGradient doesn't work for surface graphs.
+- Scatter "point" meshes do not support gradients, they always use the base color.
+- In Mac OSX 10.7 rendering only works in QML.
