That’s not video, because i think watching a video takes times.
Most of the time when i look for a particular answer, i don’t want to watch 30 minutes of video. That’s my point of view.
Tell what you think of the tutorial:
Clarity?
Difficulty?
Innovation?
Thanks for the great tutorial 
I’ll have to try the tip about converting to webgl.
i don’t get this post where is the tut?
tutorial is step how to make something from 0 to done, these?
Videos are very good to discuss and teach a concept because you have to show all steps.
This prevents you as an author writing something and the user might not be able to fully
follow because you skipped a step you might thought would not be important.
You can also jump to specific markers in a video so you do not have to watch everything.
However a video cannot be searched inside while with a text based tutorial you can keyword
search specific topics.
They all have the ups and downs.’
BTW thank you for the WebGL link - I just started to work on a project and was thinking about
using it.
