Primo prototipo di utilizzo dell'encoder/decoder Corto in Unity.

https://github.com/cnr-isti-vclab/corto

Per l'utilizzo abbiamo seguito questi passi:

1. Download ed installazione di CMake: https://cmake.org/download/
2. Configurazione per la generazione della solution (in questo caso Window per Visual Studio 2017 Community Edition)
3. Compilazione delle librerie libcorto, utility e decoder per Unity
4. Tramite KenShape abbiamo creato tre semplici mesh 3D poi compresse con l'utility corto

Esempio:

 ./corto -o bottle-potion-texture.corto .\bottle-potion-texture.obj
Encoding time: 1ms
Nvert: 610 Nface: 428

5. Creazione della cartella "Plugins" in cui inserire "cortocodec_unity.dll" (saranno necessari le altre versioni (linux, macosx, etc..) per renderlo cross-platform)
6. Creazione cartella "StreamingAssets" dove inserire i file .corto
7. Modifica degli script originali che usavano Resource.Load di Unity e nelle nuove versioni con caricavano i diversi file .corto, abbiamo preferito usare appunto "Streaming Assets" e fare una piccola modifica:

   UnityCortoSDKTest/Assets/Scripts/CortoMeshLoader.cs

   Line 14 in 762eaa1

   var PathAllFile = Path.Combine(Application.streamingAssetsPath, assetName);

8. In futuro stiamo studiando come create a runtime il materiale e la texture associata!

ENG:

First prototype to use the Corto encoder / decoder in Unity.

https://github.com/cnr-isti-vclab/corto

For use we followed these steps:

1. Download and install CMake: https://cmake.org/download/
2. Configuration for the generation of the solution (in this case Window for Visual Studio 2017 Community Edition)
3. Compilation of libcorto libraries, utilities and decoders for Unity
4. Using KenShape we created three simple 3D meshes which were then compressed with the corto utility
5. Creation of the "Plugins" folder in which to insert "corticodec_unity.dll" (the other versions (linux, macosx, etc ..) will be needed to make it cross-platform)
6. Creation of the "StreamingAssets" folder where to insert the .corto files
7. Modification of the original scripts that used Resource.Load of Unity and in the new versions with loaded the different .corto files, we preferred to use "Streaming Assets" and make a small change: https://github.com/Vytek/UnityCortoSDKTest /blob/762eaa168f3b1f568d8a12b0ff9c25094d4e2b4b/Assets/Scripts/CortoMeshLoader.cs#L14
8. In the future we are studying how to create the material and the associated texture at runtime!
