Detailed App Info:
Application Description
Tap or draw and watch CRYSTALS GROW before your eyes!
CRYSTAL FARM! What is it? It's a way to make crystals with your fingers!
Tap or draw and watch CRYSTALS GROW before your eyes: TAP to set a "seed" point, then watch the crystals grow, or DRAW an invisible curve, then watch as crystals grow along the curve!
- Draw your name, watch it grow crystals!
- Send a snapshot of the result to a friend, or use it as your lock screen.
- Select Colors the crystal start and end their growth with
- Set how long they keep growing
- Try different types of crystals -- choose from Coral (rounded), Frost (spikey), Salt (blocky) or Mutant (mixed)!
Created by working Hollywood Visual Effects artist Jeff Wolverton.
TECHNICAL QUESTIONS & ANSWERS ABOUT CRYSTAL FARM:
Q: How are the crystals grown?
A: With an algorithm I call GROWIT: it's a diffusion-limited aggregation Laplacian growth algorithm which I extended to be curve-seeded by using Euclidean distance fields via 8SSEDT. (Hey, you asked.)
Q: Huh. And are you aware that Kim, Sewell, Lin, et al. published an algorithm that is orders of magnitude faster than diffusion-limited aggregation, and hence much better than yours?
A: Um...yeah. Are you aware that I totally don't care?
Q: Is that your way of saying you read the Kim & Lin paper, but you were too dumb to figure it out?
A: No, that's my way of saying you have a big stupid head. Who ARE you, anyway?
