# fsbrain surface-based animations

These are animations created using the [fsbrain R package](https://github.com/dfsp-spirit/fsbrain/), with a lot of internal help from [rgl](https://CRAN.R-project.org/package=rgl) and the [ImageMagick library](https://imagemagick.org).

![Vissurfaces](https://github.com/dfsp-spirit/fsbrain_gallery/raw/master/surface/animations/fsbrain_morphnat_curv_web.gif?raw=true "Rotating brain mesh with mean curvature plotted onto it, rendered with fsbrain")

**Animation 1:** Rotating visualization of [mean curvature](https://en.wikipedia.org/wiki/Mean_curvature) plotted onto the white surface of a subject (native space).


# More descriptors and brain parcellations (GIF format)

Have some bandwidth to spare? Try some of these large versions for different surface-based morphometry measures in native space:


* [Mean curvature (12 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_morphnat_curv.gif)
* [Jacobian white (9.3 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_morphnat_jacobian_white.gif)
* [Sulcal depth (9.0 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_morphnat_sulc.gif)
* [Mean Geodesic distance (11 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_morphnat_geodesic_white.gif)


Here are some brain surface parcellations:

* [The Desikan-Killiany Atlas (5.9 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_atlas_aparc.gif)
* [The Destrieux atlas (6.8 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_atlas_a2009s.gif)


Here is some standard space data, smoothed at FWHM 10 and visualized on the *fsaverage* template:

* [White surface area (10 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_morphstd_area_fwhm10.gif)
* [Mean curvature (12 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_morphstd_curv_fwhm10.gif)
* [Local Gyrification Index (10 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_morphstd_pial_lgi_fwhm10.gif)
* [Sulcal depth (11 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_morphstd_sulc_fwhm10.gif)
* [Cortical thickness (11 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_morphstd_thickness_fwhm10.gif)
* [Cortical volume (11 MB)](https://github.com/dfsp-spirit/fsbrain_gallery/blob/master/surface/animations/fsbrain_morphstd_volume_fwhm10.gif)


# Encoded videos

If you prefer videos over GIF animations, you can check out the [fsbrain channel on vimeo](https://vimeo.com/channels/fsbrain) or the [fsbrain channel on youtube](https://www.youtube.com/channel/UCJAJZDnPS9Xtng-TTbIn2Dg).

These videos were created from the animation frames using [ffmpeg](https://www.ffmpeg.org/).
