Houdini Lsystem Rule Codes for procedural tree setup
Houdini procedural tree , bush and leaf orient calculating system node view for our cartton tv series
Calculating point denstiy through red and black. Black parts are close to the tree and that parts emiting minimum points and red parts emitting maximum count of points. And also my system calculating area and scattering by area size.
Creating new orient data with calculating each bushes' centroid and multiplying normals with -1 and creating new orinet with this vop
Creating new orient with taking data from new normal. This vop giving us a new orient shape like top part of the bush taking straight normals and as long as it goes to down of the bush , normals going down.
Exporting data to XSI
Wind dynamic sim vop. This vop allow us to create a wind using worl scale turbulance
Created this procedural tree system while working at Lighthouse VFX. This system allow us to create buch of trees , creating leaf , leaf orientation , wind simulation and so.
This system creating procedural tree using Houdini Lsystem , VOP & VEX:
-Calculating Tree's bush size and emitting asme amouth of points. With this method , each meshes emitting same number of points and tree looks more natural
-Creating new normal & Orient. System creating a new normal point between center of mesh and top of mesh and each normal looking apoosite of that direction. With that data creating new orient for leaves
-Creating wind dynamics for leaves and bushes with VOP.
-Creating 4 color and scale leaves. Created 16 polygon grid and projecting a leaf texture. After teture is done creating 3 more shape and giving them darker and brigther color to make them look more natural.
