Houdini:L-system sample02

Houdini Advent Calendar2016 I paticipated on the16th day.
It is an example fo Houdini’s L-System in the last continuation.

Sample011

Permise F-F-F-F-F-F-F-F
Rule 1 F=F–F+F+F+F+F+F+F–F
Angle 45
Generations 1

 

Sample012 – Koch_Curve 01

Koch curve

lsystemsample_v001t04-koch_curve01-0001

Permise -F
Rule 1 F = F+F-F-F+F
Angle 90
Generations 4

 

Sample013 – Koch_Curve 02

This is also Koch curve. Famous shape(rotated 90 degrees)

lsystemsample_v001t04-koch_curve02-0001

Permise F
Rule 1 F = F-F++F-F
Angle 60
Generations 4

 

Sample014 – Koch_Curve 03

An annular version of the Koch curve.

lsystemsample_v001t04-koch_curve03-0001

Permise F++F++F
 Rule 1  F = F-F++F-F
 Angle 60
 Generations  4

 

Sample015 – Koch_Curve 04

This is probably the Koch curve….maybe

lsystemsample_v001t04-koch_curve04-0001

Permise F
 Rule 1 F = F+F|F+F
 Angle 60
 Generations 5

 

Sample016 – Koch_Curve 05?

Is this Koch.

Permise F-F-F-F-F
 Rule 1 F=F-F++F+F-F-F
 Angle 72
 Generations 4

 

Sample017

Permise F
 Rule 1 F = FF[+F][-F]
 Angle 60
 Generations 8

 

Sample018

Permise FX
 Rule 1 F = FF[+F][-F]
 Angle 120
 Generations 6

 

Sample019

Permise F+F+F+F+F+F
Rule 1 F=F++F-F-F-F-F++F
Angle 60
Generations 6

Sample020

Around and aournd.

Permise L
Rule 1 L = S
Rule 2 S = F”+[f-Y[S]]F;G
Rule 3 Y = –[|F-F–FY]-
Rule 4 G = FGF[+F]+Y
Angle -3832
Generations 30

 


I increase it while rotating the shape using Copy(SOP)

For example. rotate by 60 degrees to increase to 6 pieces.

Things like snowy crstals can be made quite easily.
Those kaleidoscope type things can not be judged because they make fun patterns even if made properly.
Also, it’s interesting to change the pattern by moving parameters such as Angle.


Sample021 – Snowflake01

Permise F
Rule 1 F = FF[+F][-F]
Angle 90
Generations 6

これ、Angle違いでいろんな模様がつくれておもしろい。

I changed Angle Value.

Sample022 – Snowflake02

Permise F
Rule 1 F = ffF[++FF][–FF]
Angle 60
Generations 4

Another Angle Value.
Angle=30

Sample023 – Snowflake03

Permise GF
Rule 1 F = F[+”F][-“F]FG[+F[“F]][-F[“F]]FG
Angle 122
Generations 3

Sample024 – Snowflake04

Permise GF
Rule 1 F = F[+F][-F]FG[+F][-F]FG
Angle 122
Generations 3

Smaple025 – Snowflake05

Permise fff+fff–F
Rule 1 F = F[+F][-F]FG[+F][-F]FG
Angle 60
Generations 3

Sample026 – Snowflake06

Permise ffffffffffffff+++F
Rule 1 F = F[+F][-F]FG[+F][-F]FG
Angle 60
Generations 3

that’s all!
It was an example of L-System.
