-# bigdataviewer-vistools
-Helpers to use BigDataViewer as a quick visualization tool in other projects.
-This is intented to replace/augment `ImageJFunction.show()` from [imglib2-ij](https://github.com/imglib/imglib2-ij).
+nothing here
 
-Please note, that this is still in early stages of development.
-Documentation is sparse.
-API will break frequently in the foreseeable future.
+### This project has been merged into [bigdataviewer-core](https://github.com/bigdataviewer/bigdataviewer-core).
 
-## Usage
-
-```
-Random random = new Random();
-Img<ARGBType> img = ArrayImgs.argbs(100, 100, 100);
-img.forEach(t -> t.set(random.nextInt()));
-Bdv bdv = BdvFunctions.show(img, "img");
-```
-creates a random 3D ARGB img and shows it in a BDV window.
-
-All `BdvFunctions` methods will return some instance of `Bdv` which can be used to close the BDV window:
-```
-bdv.close()
-```
-or add more stuff to the same window:
-```
-BdvFunctions.show(img2, "img2", Bdv.options().addTo(bdv));
-```
-Via `bdv.getBdvHandle()` you can get access to the BDV `ViewerPanel` and `SetupAssignments` allowing more fine-grained
-manipulations of BDV state.
-
-The concrete `Bdv` instance returned from `BdvFunctions.show(img, "img")` in the above example is `BdvStackSource<ARGBType>` and
-has additional methods, e.g., `removeFromBdv()` which removes `img` from the BDV window.
-
-To display a 2D image, display a 3D image as a stack of 2D slices over time etc:
-```
-BdvFunctions.show(img2, "img2", Bdv.options().is2D());
-```
-The `is2D()` option is per Viewer window, not per stack. If it is set, the BDV navigation mouse and keybindings are set up for 2D, etc...
-
-More fine-grained control can be achieved with `axisOrder()` option:
-```
-BdvFunctions.show(img2, "img2", Bdv.options().is2D().axisOrder(XYT))
-```
-`AxisOrder` specifies how the stack dimensions are interpreted.
-For BDV with 3D navigation, the follwoing are useful: `XYZ, XYZC, XYZT, XYZCT, XYZTC`.
-For BDV with 2D navigation, the following are useful: `XY, XYC, XYT, XYCT, XYTC`.
-You should interpret `C` and `T` losely. The effect is that `T` will be mapped to the time slider of the BDV,
-while `C` is mapped to BDV sources.
-(This also means that you should not have images with a large `C` dimension.)
-
-There is/will be stuff to add annotation overlays. Currently `BdvFunctions.showPoints()` is available.
-
-Here is an example screenshot where several 3D stacks, a set of boundary points, and 3D ellipsoids fitted to the boundary points were added to a BDV window. It also shows how the usual BDV dialogs can be used to adjust visibility / brightness / colors of tbe individual sources.
