2D LSystems

Bracket-Rule

---

Stochaic Replacement Rule

---

• Put %x behind a rule
  • x is a double with "." as decimal point (always type a decimal point)
• If you don't use %x, then the probability of this rule is automatically 100%
• The percentages get added in order
• What if the sum is under 100:
  • The resting percentage get filled with a "do not replace" rule
  • Eg: Rules: F -> "F+F" %50, G->"F-(F+F)" | Now there is a 50% chance F->"F"
• What if the sum is above 100:
  • This wil not cause an error, it will only result in unexpected outcomes
  • Eg: Rules: F -> "F+F" %70, F->"F-F" %50 | The chance for "F-F" is actually 30% not 50%
  • Eg: Rules: F -> "F+F" %10, F->"F-F" | The chance fo "F-F" is actually 90%
  • Eg: Rules: F-> "F+F", F->"F-F" %70 | The chance for "F-F" is actually 0% not 70%

Lighting

---

Ambient Light

---

Diffuse Light

---

Infinity Light

This light only has a pointing direction.

---

Point Light

This light onlyl has a location.

It could be a spotlight, if the spotangle != -1.
