Drawing test in a Virtual Texture ( video version of this post ).

You can admire my special coder art drawing skill….

I have also implemented a Undo/Redo mechanism and a simple Brush who is drived by the velocity and the pressure of a Wacom stylet.

The fps is clamped to 30 because of the video capture but the application run in full 60 fps all the time.
Due to virtual texturing caching and full hardware rendering it’s possible to cover very large part of the picture without sacrifying the fluidity of the application ( unlike a lot of drawing software who suffer server lag in that case ) and then to produce some kind of nice Calligraphy.
