## 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 developed as a [Kotlin multiplatform](https://kotlinlang.org/docs/reference/multiplatform.html)
|
|
application, currently targeting browser JavaScript and JVM.
|
|
|
|
## Requirements
|
|
|
|
JVM backend requires JDK 11 or later
|
|
|
|
## 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.
|
|
|

##### 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 `SolidGroup` class via `PrototypeHolder` interface, and
|
|
`SolidReference` class helps to reuse a template object.
|
|
|
|
##### Styles
|
|
|
|
`VisionGroup` has a `styleSheet` property that can optionally define styles at the Group's
|
|
level. Styles are applied to child (descendant) objects using `Vision.styles: List<String>` property.

|
## Visualization for External Systems
|
|
|
|
The `visionforge` framework can be used to visualize geometry and events from external,
|
|
non-Kotlin based systems, such as ROOT. This will require a plugin to convert data model
|
|
of the external system to that of `visionforge`. Performing such integration is a work
|
|
currently in progress.
|
|
|
|
|
|
## Demonstrations
|
|
|
|
The `demo` module contains several example projects (demonstrations) of using the `visionforge` framework.
|
|
They are briefly described in this section, for more details please consult the corresponding per-project
|
|
README file.
|
|
|
|
### Simple Example - Solid 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.

## Thanks and references
|
|
The original three.js bindings were made by [Lars Ivar Hatledal](https://github.com/markaren), but the project is discontinued right now.

|
|
All other libraries are explicitly shown as dependencies. We would like to express specific thanks to JetBrains Kotlin-JS team for consulting us during the work.
