The link support means that an object can now appear in more than one
places, and even inside a document different from its own. This patch
adds support for in-place editing, meaning that the object can be edited
at correct place regardless where it is.
See [here](https://git.io/fjPIk) for more info about the relavent APIs.
This patch includes two example of modifications to support in-place
editing. One is the ViewProviderDragger, which simply adds the dragger
node to editing root node by calling
View3DInventorViewer::setupEditingRoot(dragger). The other much more
complex one is ViewProviderSketch which calls setupEditingRoot(0) to
transfer all its children node into editing root. ViewProviderSketch
also includes various modifications to command invocation, because we
can no longer assume the active document is the owner of the editing
object.
This patch also includes necessary modification of the 'Show' module to
support in-place editing.
The patch implements context-aware selection and rendering in 3D view.
Please check [here](https://git.io/fjiY5) for more details, including
the following 'Render Caching' section.
The patch also includes modification of View3DInventorViewer to support
always-on-top selection rendering using the secondary selection context
and the new coin node SoFCPathAnnotation.
Another small change in SoQtQuarterAdaptor for more responsive frame
rate display. The original implementation reports skewed frame rate
in the presence of long idle period.
+ handle destruction of GL context in 3d viewer class
+ fix for OpenGL error message: 'Texture is not valid in the current context. Texture has not been destroyed'
+ disable VBO rendering in split views
+ activate multi-sampling in split view for manual alignment
+ share GL widget in case a document has multiple views to make VBO rendering work correctly
*First step to move Part rendering using VBO instead of direct rendering
*Update comments inside the code
*Assume VBO is available if OpenGL > 3.0 is detected
*Add initial Color support to VBO rendering !
*Initial full feature VBO rendering implementation
*Modify some include issue for linux build
*Try to fix linux include header
*Reupdate header include for linux support
*Fix compilation on linux
*Fix linux and MacoOS build
*Fix glGetString definition
*Fix Windows build
*Add VBO support as an option into the Preference menu
*Fix crash while running FreeCAD test bench with new VBO rendering infrastructure (in both cases)
*Improve performances
*Compute material index only when a VBO update is required (improve frame rate by 10%)
*Clean the code
*Fix Travis compilation warning
*Try to fix Windows compilation issue
*Update include for Windows
As quarter is not wrapped by SWIG we need to expose our own python interface class.
This is a start with the most important functions to access the render and event
manager. Furthermore all extra functions available next to the swig wrapper functions
are exposed. Everything else can be added when needed.
-removes all soqtviewer references
-create a quarter adaptor class which implements missing functionality
-adopts freecad code to make use of SoRenderManager and changed View3DInventorViewer interface
