Black Hole
I made a black hole. I know, there is absolutley no beat detection, but I just think it looks very real. Tell me what you think.

doesn't look very black-holey to me. Black holes are black because all light escapes them. To see a black hole, you have to see the material being sucked in. To me, this looks more like a low-end galaxy.

Your DM is very unoptimized
t=6.9; You never use t, so why do you define it?

t=7*pow(.23); pow() needs two inputs- a number and the power you raise it to. This is useless also.

alpha=d*acos(-1);r=x/y;

r is never used because you have "no movement (just blend) selected.
Also, you don't need to calculated acoS(-1) in every frame. change acos(-1) to p and put p=acos(-1) in init.

In the bump:
x=0.5+0*0.3;
y=0.5+0*0.3;
t=t+0.1;

t is never used, so remove it.
Any number times 0 equals zero, so you can remove the +0*0.3 in both x and y.

I would put the colorfade before the DM- it looks smoother that way and you can remove the blur.

actually.... it does look pretty real except that more towards the center there would be an area where it becomes totally black where (as previously stated) the gravity becomes too strong for the light to escape. In my opinion it would look great if you changed the colors and added a background so it would look like satellite photos of a hurricane.

Good job by the way!

I think its a cool preset. More like a nebula than a black hole in my opinion though. Good preset either way.

More like a galaxy.

Nice, whatever it looks like :D. Actually, it kinda looks like a spinning black hole's gravity field.

I was bored...
oh and sorry about the fps :D

Not bad...the land looks a little too dynamic. The hurricane should have denser twirls and be more opaque.

wow! Akuso makes some cool rmx's:D

Fix this please!

Too dynamic, I agree. But it looks like it should be more dense...

You could try using a BMP of earth (like UnConeD did in Nuclear Warfare) and use that for your land.


19th July 2003 17:05 UTC

thats not me though... and I already tried and it didn't turn out right

The land looked better in my Earth&Sky preset but its already WAY to similar (the DMs, The overall concept, The way I used the water effect to make land)

you know of anyway to make the land movement not look so....
fluidy?
fluid-like?
watery?

whatever

What you could do is add the landscape gen to an EL that is enabled onbeat for one frame (add a custom bpm of skipping 10 beats). It should output the land once, making it change every ten beats. If you want, for your landscape gen, you could try something like i did in "lscape" in utter psychosis i (it is in this forum) and toy with it until you get a good-looking generator.

yeah... it looks great and I'd lave to do stuff like that but I suck at scopes... still trying to learn it

Its not that hard at all, it basically just draws randomly.


oxp=xp;oyp=yp; This sets the starting point of the new line to the endpoint of the old line

xp=xp+(rand(200)-100)/1500;yp=yp+(rand(200)-100)/1500; This adds a random value to the last endpoint to form the new starting point

oxp=if(above(abs(xp),1),-sign(xp),oxp);oyp=if(above(abs(yp),1),-sign(yp),oyp); xp=if(above(abs(xp),1),-xp,xp);yp=if(above(abs(yp),1),-yp,yp);The wrapping code
cnt=0;Sets cnt to 0 (used in line creation)

x1=oxp;
y1=oyp;
x2=xp;
y2=yp;
x=if(cnt,x1,x2);
y=if(cnt,y1,y2);
cnt=cnt+1;
/\ this is pretty straightforward. If cnt=0 then it draws the starting point. If cnt = 2 it draws the ending point.

The wrapping code allows for seamless tiling with DMs

When doing this, I started with dots and it just moved around the screen. That left gaps, so i turned it into lines. Then, I realized that I wanted a DM to zoom, pan, and scroll, so I added the wrapper.

Brilliant!
