## rntviewer
This is a work-in-progress interactive visualization tool for [RNTuple](https://root.cern.ch/doc/v618/md_tree_ntuple_v7_doc_README.html).
### Getting the repo
Clone this repository with
```
$ git clone --recurse-submodules
```
### Dependencies
rntviewer currently only works on Linux (PRs welcome).
The dependencies are:
- GLFW3 (`libglfw3-dev` on debian, `glfw-devel` on fedora, `glfw` on arch)
- ROOT (likely bleeding edge version, compiled from sources)
- libxxhash3-dev
Other than those, rntviewer depends on Dear ImGui and GLAD (both included in the source tree).
The machine must support OpenGL 4.
### Building
Building is done with `make`. Make sure to `source /path/to/root/bin/thisroot.sh` before running it.
You probably want to build the release version:
```
$ make r
```
You can test that the tool is working properly with:
```
$ ./rntviewer ntpl lmext1.root
```
### Usage
```
$ ./rntviewer
```
