Surface fading
I got a question.

How to make a surface fade in the distance?

I use the following code to make a surface:

d=d/((y*2.2+3)*2)

Now this works perfectly, but if i make the last 2 bigger (for example 5) it gets a little messy in the further parts of the surface.

Is there an easy way to make a sort of fade or smog in that distance? Any help would be greatly appreciated,

Thanks in advance,

You want to use alpha blending. Search the forums to figure out how.

ok, since something about movement is started, i wanted to ask a question, but didnt want to start a new thread for it, because it is probably stupid.
in static movment for polar coord d=0..1. then how does d=-d work.
does avs convert polar into rectangular coords?

It reverses the distance from the center of the screen for each pixel. This effectively rotates it about the origin(I believe).

so id d=-1 then does avs convert it into rect coords so:
x=sin(r)*d;
=sin(r)*-1
y=cos(r)*d;
=cos(r)*-1;
i think this will rotate the thing, otherwise how can distance be negative?

Arg, my reply didn't post. :mad:

Imagine a series of lines all going through origin (d=0). Each point on the screen is identified a distance down the line. When d is negative, it goes down the line in the opposite direction.

Shreyas: ALWAYS start a new thread if it's about something else. Adding stuff to non-related threads makes the forum harder to search.
