Examples of geographical data visualization with Unity VFX Graph

GeoVfx

This is a Unity example project that shows how to use Visual Effect Graph (VFX Graph) for geographical data visualization.

The data shown in this visualization is based on Gridded Population of the World (GPW) v4 provided from NASA. Please see the SEDAC page for further details.

In the example project, geographical data is contained in .geodata custom texture files. These files were generated from .geotiff files using this notebook. You can use Jupyter, Colaboratory or your own local Python environment to run this script.

UnityEngine.VFX.Utility error

Hi, while trying to run the project I encountered a couple of errors that I can't solve.

• error CS1061: 'VisualEffect' does not contain a definition for 'HasGraphicsBuffer' and no accessible extension method 'HasGraphicsBuffer' accepting a first argument of type 'VisualEffect' could be found (are you missing a using directive or an assembly reference?)

• error CS1061: 'VisualEffect' does not contain a definition for 'SetGraphicsBuffer' and no accessible extension method 'SetGraphicsBuffer' accepting a first argument of type 'VisualEffect' could be found (are you missing a using directive or an assembly reference?)

It seems that both errors has something to do with a dependency called UnityEngine.VFX.Utility. I searched the web for info but I haven't been able to find it. Do you know what can be done about it? I'm very new to VFX.

Having a hard time building this - something about KlakMath?

Thank you for this amazing work! It is a fantastic way to learn about Unity and VFXGraph.

Unfortunately, I have a problem. When I open the GeoVfx project, I get:

Unity Package Manager Error

An error occurred while resolving packages:
  Project has invalid dependencies:
    jp.keijiro.klak.math: Error when executing git command. xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun


A re-import of the project may be required to fix the issue or a manual modification of /Users/gianpablo/Documents/Unity Projects/GeoVfx/Packages/manifest.json file.

Click on Retry to relaunch Unity and reopen your project.

Click on Continue to launch Unity.  Some or all packages may not be imported which may cause compilation errors.

I downloaded the Klakmath repo, but I can't seem to import it as a package.
