This is a fork of BVV to play around with some new features:

• using LUTs;
• using gamma correction;
• using different volume render methods (transparency/illumination);
• clipping of displayed sources in shaders without reloading them.

Currently synced to BVV version 0.3.3 (this commit).

Download latest zip archive with jar files from releases
(it is called bvv-playground-X.X.X_jar_files.zip),
extract and put them to the jar folder of the latest FIJI installation.

The plugin should appear in the Plugins>BigDataViewer>BVV-playground

It works in the same way as BigVolumeViewer, but there are some new additional features (see below).

First of all, "Brightness and Color" dialog (shortcut S) is different:

*(works also with Cards panel, activated by shortcut P)

It uses range sliders (and one can pull the range by dragging the middle interval).

A standard "brightness" is now called "LUT range", it maps image intensity values to specific colors. This mapping can be done non-linearly by adjusting "LUT γ", gamma value (a power-law).

In addition to color, one can also independently map intensity values to an opacity of voxel using "α range" (with a corresponding "α γ" gamma adjustment slider below).

A new additional checkbox on the left is used to synchronize top pair of sliders (LUT) with the bottom pair (α), but not the other way around. It also synchronizes ranges in the extended view (>> button).

A new shortcut O (letter) is used to switch between "Maximum intensity projection" and "Volumetric" rendering. By "volumetric" I mean "transparency" or "alpha-blending" ray-casting. These two different render methods are illustrated below:
Maximum intensity

Volumetric

Displaying volumes with LUTs and clipped view at the current stage are available only from the code (see an example).

A list of additional methods (adding LUTs and volume clipping) is illustrated by this example.
There is a possibility to specify "clipping transform", shown here.

The project is currently under development and has a lot of "experimental" code (i.e. not clean and in the state of "well, at least it works"). So comments and optimization suggestions are welcome.
