Questions about speed and sound

[Exan]

Stone-D. I speak english as a second language and so I don't know all the terms. And since my friend is a finn, I speak finnish with him so I don't use words like raytracin or 3D rendering. I use finnish terms though they aren't much better than my english ones.

Besides I'm very dum when it comes to 3D so I try to avoid talking too much of it and make fool of myself. Doesn't work most of the time.

I guess the point is, prepare to tolerate strange and funny english on my behalf.
