# Bevy Voxel Plot

A simple and efficient Voxel Plot for [Bevy](https://bevyengine.org).

Developed for data visualisation purposes (e.g. pointclouds/voxelplots of 3D structures).

It uses instancing and is an adaptation of the

`custom_shader_instancing.rs` [example of bevy](https://github.com/bevyengine/bevy/blob/main/examples/shader/custom_shader_instancing.rs)

which also supports opacity control.

Able to plot 2 million voxels on an M2Pro Macbook Pro.

## Examples:

```shell

cargo run --release --examples bevy_egui

```

- Bevy Pan Orbit Camera

Simple implementation of the Voxel Plot along with the `bevy_panorbit_camera` crate.

- Bevy Egui

More advanced implementation of the Voxel Plot along with the `bevy_panorbit_camera` crate inside an `egui` image

texture, implemented with the `bevy_egui` crate.

- Bevy Pointcloud Bunny

Load the test file `bunny.pcd` from [pcl](https://github.com/PointCloudLibrary/pc) and display it as colorful voxels with

low alpha.

## Version Compatibility

| bevy | bevy_voxel_plot |
