Simple wave effect.

I was tinkering around with creating a diffusing function earlier today. It occurred to me that if I added a velocity state that it could make a wave effect. Lo and behold, it worked!

waves.c

Execute the following command to run it.

Code:

gcc waves.c -o waves -std=gnu99 -framework OpenGL -framework GLUT && ./waves

I simply run vertlet integration after the diffusing function. This can be easily extended to animate a 2D array.

I just spent a half hour hacking with it, its still working but now I get this error

Code:

waves[1096] *** -[NSBundle load]: Error loading code /Users/theuser/Library/InputManagers/

Smart Crash Reports/Smart Crash Reports.bundle/Contents/MacOS/Smart Crash Reports 

for bundle /Users/theuser/Library/InputManagers/Smart Crash Reports/Smart Crash Reports.bundle, 

error code 2 (link edit error code 0, error number 0 ())

If there were tutorials based on fun looking stuff like that, I might get past "hello world", I just might break out those C/C++ books buried around here somewhere.

That looks like you've installed the nasty "Smart Crash Reports" input manager, nothing to do with Skorche's code...

Ah, wonder when that got thrown into the mix. Xcode install?

No, Apple doesn't do or endorse such hackery. Some devious piece of third-party software, mostly likely.

I get this error when running it:

Quote:2007-04-17 15:03:59.989 waves[300] *** -[NSBundle load]: Error loading code /Users/jeddhaberstro/Library/InputManagers/Menu Extra Enabler/Menu Extra Enabler.bundle/Contents/MacOS/Menu Extra Enabler for bundle /Users/jeddhaberstro/Library/InputManagers/Menu Extra Enabler/Menu Extra Enabler.bundle, error code 2 (link edit error code 0, error number 0 ())

But I get that everytime I run and compile something, and it doesn't seem to affect anything (Skorche's demo seems to run fine

)

Hey guys, stop bashing my beloved InputMangers!

There are already rumors that Apple won't allow them in Leopard because of "issues" like those mentioned in these posts.
