Houdini - Procedural Volume trail


感謝大神John Kent傳授的小技巧

1. Create line, resample it.

2.  Create a "polygon" circle sweep it with the line and skin it.

3. Convert to mesh

4. uvtexture - type: Rows & Columns, set attribute type to point

5. Point vop

6. Carve anime with Second U

7. Using Carve separate different section, polycap and vdbfrompolygon

8. Merge all  (optional :  Primitive > adjust visualization )
