## Introduction
|
|
|
|
This repository contains a [DataForge](#about-dataforge)\-based framework
|
|
used for visualization in various scientific applications.
|
|
|
|
The main framework's use case for now is 3D visualization for particle physics experiments.
|
|
Other applications including 2D plots are planned for the future.
|
|
|
|
The project is being developed as a Kotlin multiplatform application, currently targeting browser
|
|
JavaScript and JVM.
|
|
|
|
|
|
## Features
|
|
|
|
The main framework's features for now include:
|
|
- 3D visualization of complex experimental set-ups
|
|
- Event display such as particle tracks, etc.
|
|
- Scales up to few hundred thousands of elements
|
|
- Camera move, rotate, zoom-in and zoom-out
|
|
- Scene graph as an object tree with property editor
|
|
- Settings export and import
|
|
- Multiple platform support
|
|
|
|
|
|
## About DataForge
|
|
|
|
DataForge is a software framework for automated scientific data processing. DataForge Visualization
|
|
Platform uses some of the concepts and modules of DataForge, including: `Meta`, `Configuration`, `Context`,
|
|
`Provider`, and some others.
|
|

## Modules contained in this repository
|
|
|
|
### dataforge-vis-common
|
|
|
|
Contains a general hierarchy of classes and interfaces useful for visualization.
|
|
This module is not specific to 3D-visualization.
|
|
|
|
The `dataforge-vis-common` module also includes configuration editors for JS (in `jsMain`) and JVM (in `jvmMain`).
|

|
### dataforge-vis-spatial
|
|
|
|
Includes common classes and serializers for 3D visualization, Three.js and JavaFX implementations.
|

|
|
##### Prototypes
|
|
|
|
One of the important features of the framework is support for 3D object prototypes (sometimes
|
|
also referred to as templates). The idea is that prototype geometry can be rendered once and reused
|
|
for multiple objects. This helps to significantly decrease memory usage.
|
|
|
|
The `prototypes` property tree is defined in `VisualGroup3D` class, and `Proxy` class helps to reuse a template object.
|
|
|
|
##### Styles
|
|
|
|
`VisualGroup3D` has a `styleSheet` property that can optionally define styles at the Group's
|
|
level. Styles are applied to child (descendant) objects using `styles: List<String>` property defined
|
|
in `VisualObject`.
|
|
|
|
|
|
### dataforge-vis-spatial-gdml
|
|
|
|
GDML bindings for 3D visualization (to be moved to gdml project).
|
|
|
|
|
|
### dataforge-vis-jsroot
|
|
|
|
Some JSROOT bindings.
|
|
|
|
Note: Currently, this part is experimental and put here for completeness. This module may not build.
|
|
|
|
|
|
## Demonstrations
|
|
|
|
The `demo` module contains several demonstrations of using the `dataforge-vis` framework:
|
|
|
|
### Spatial Showcase
|
|
|
|
Contains a simple demonstration with a grid including a few shapes that you can rotate, move camera, and so on.
|
|
Some shapes will also periodically change their color and visibility.
|
|
|
|
To see the demo: run `demo/spatial-showcase/Tasks/distribution/installJsDist` Gradle task, then open
|
|
`build/distribuions/spatial-showcase-js-0.1.0-dev/index.html` file in your browser.
|
|
|
|
##### Example view:

|

|
|
|
|
|
### Muon Monitor Visualization
|
|
|
|
A full-stack application example, showing the
|
|
[Muon Monitor](http://npm.mipt.ru/projects/physics.html#mounMonitor) experiment set-up.
|
|
|
|
Includes server back-end generating events, as well as visualization front-end.
|
|
|
|
To run full-stack app (both server and browser front-end), run
|
|
`demo/muon-monitor/application/run` task.
|
|
|
|

|
|
|

|
|
|
### GDML Example
|
|
|
|
Visualization example for geometry defined as GDML file.
|
|
|
|
To build the app, run `demo/gdml/Tasks/distribution/installJsDist` task, then open
|
|
`build/distribuions/gdml-js-0.1.0-dev/index.html` file in your browser, and
|
|
drag-and-drop GDML file to the window to see visualization. For an example file, use
|
|
`demo/gdml/src/jsMain/resources/cubes.gdml`.
