first experiments to achieve Global Illumination using Voxel Cone Tracing.

Adding diffuse indirect lighting. As you can see noise and perfomance impact are still very noticeable. I hope to reduce those issues in the near future.

I am taking inspiration by studying the following amazing resources:

. …

Finally implemented proper day/night cycle inside my custom OpenGL render.

Now the engine can vary sun position according to hour and day of the year, and also according to the latitude, with a good approximation.
