| Qt Data Visualization 1.2 |
| |
| New features |
| ------------ |
| |
| - Added support for volumetric custom objects (QCustom3DVolume) for rendering 3D voxel data. |
| - Reflection support for bar graphs (floor only). |
| - Polar horizontal axes supported for scatter and surface graphs. |
| - Added flipHorizontalGrid property for surface to enable displaying grid in 2D orthographic |
| projections of the surface (e.g. 2D spectrogram graphs). |
| - Added horizontalAspectRatio property for graphs to enable better control over graph dimensions. |
| - Added an API for setting a custom texture for a surface series. |
| - Added several properties to control the default input handler behavior. |
| - Exposed default input handlers to QML API. |
| - Camera can now be targeted at any point within axis ranges on the scatter and surface graphs. |
| On bar graphs, camera target is limited to any point on the graph floor. |
| - Added possibility to scale custom items based on data ranges. |
| - Added a property for specifying the locale for the graph, which affects how various labels |
| are formatted (e.g. which character is used for the decimal point). |
| - Added a property for specifying the Y-value of the floor level on bar graphs. |
| - Added a property to Q3DScene for querying the graph position at a screen position. |
| - The default input handlers now zoom to cursor/pinch instead of zooming toward the center of the |
| graph. Added a property to restore the old zoom behavior. |
| - Added properties to control the minimum and maximum allowable zoom level of the camera. |
| - Added a method for getting the list of custom items added to the graph. |
| - Added a property for specifying the graph background margin. |
| |
| Fixed issues |
| ------------ |
| |
| General: |
| - Label widths now update consistently when axis range changes. |
| - Made selection texture creation more robust. |
| - Grid lines and labels no longer change size if aspect ratio changes. |
| - Q3DTheme::ColorStyleObjectGradient now works for surface graphs. |
| - Removed the superfluous common.pri. |
| - Fixed non-visible selected object drawing in static optimization mode. |
| - Gradient color styles are now supported equally in both default and static optimization modes. |
| - Specular highlight now works with rotated objects in static optimization mode. |
| - Fixed a crash in static optimization mode when data is updated without resizing. |
| - Fixed changing items in static optimization mode. |
| - Fixed issues with static optimization mode when some items were outside axis ranges. |
| - Slice mode grid lines should no longer vanish into the background when using high ambient light |
| value. |
| - Reduced the size of the surface selection texture, allowing selection to work with larger |
| surfaces. |
| - Fixed QAbstract3DGraph::renderToImage in OpenGL ES2 environments. |
| - Fixed crash when attempting to enable slicing without row/column selection modes. |
| - QCustom3DLabels now use the same shader as other labels, which means the specular highlight |
| no longer makes camera facing custom labels unreadable with some themes. |
| - Made various selection queries thread safe. |
| - Fixed selection query synchronization issue when using threaded renderer. |
| - Font size is automatically reduced if the label gets too wide to fit the label texture. |
| - Fixed the ordering of the subviews. |
| - Fixed surface normals in cases where the surface values were not in the same order |
| (ascending or descending) along both axes. |
| - Fixed a crash when removing and changing items on the same render frame. |
| - Fixed an issue with grid line color on surface graphs. |
| - Prevented selecting bars through the floor in bar graphs. |
| - Fixed recurring GL_INVALID_VALUE OpenGL errors. |
| - Improved the surface shadows. |
| - Fixed the OpenGL context cleanup upon renderer destruction. |
| - Fixed scatter item autosizing when adding a new series. |
| - Fixed a crash related to selection render buffer reuse. |
| - Fixed the flipped Z-coordinate for absolutely positioned custom items. |
| - Fixed shadows when viewing the graph directly from above or below. |
| - Fixed problems using large custom meshes where vertex index count overflowed unsigned short. |
| |
| New examples |
| ------------ |
| |
| - Qmlspectrogram example added. It shows how to display 2D spectrogram using surface graph with |
| gradients and orthographic projection. Also demonstrates the use of polar axes. |
| - Bars example now demonstrates zooming to selection, which leverages the new ability to |
| control the camera target. |
| - Textured surface example added. |
| - Volumetric example added. It shows how to use the new QCustom3DVolume object to visualize |
| volumetric data. |
| - Reflection added to Bars and Customproxy examples. |
| - Custom camera targeting added to Bars example. |
