What's Up? The Demo Collection contains some little apps related to mathematical topics I wrote out of my desire to know. In most cases inspired by lessons at FHT Esslingen

Bézier.exe: I simply wandted to create a Bezier screensaver... :)

Exponential.exe originally (Option a) demonstrated the exponential growth of water lilies to saturation in a lake.
Here C is the saturation, D the starting value and lambda the speed of growth.
In a second variant (Option b) the formula has been slightly modified.

Foruriersynthese.exe draws periodical oscillations by using fourier synthesis.
The Output is a rectangle signal (Option a), a sawtooth (Option b) or a free definalble curve (Option c).
Each oscillation can be scaled and animated by dynamical shift.
The resulting curve can be put out as sound.
Special Features
  • Lots of key commands...
  • generates nics looking images.
