[edit] What it does

A file SOP will read in geometry from disk. Specific information as to which formats are supported can be found in the $HFS/houdini/GEOio file. Currently though, here are the file formats supported in Houdini7 :

• bgeo
• geo
• bpoly
• poly
• dxf
• eps
• iv
• lw
• lwo
• med
• obj
• sdl
• igs
• iges
• ply
• gz

[edit] How Do I?

[edit] Example 1

The great thing about the File SOP is that it can easily read in sequences of geometry without much work.

If one has an geometry sequence called foo (foo.1-100.obj). Merely replace the frame number with $F to read in the relevant geometry for that frame. ie. foo.$F.obj.

[edit] Example 2

Expressions can also be used to exactly define which geometry to read in. Expressions should be enclosed with ` ` (the tilde key). For instance if I want to clamp my frame range down from 1-100 to 20-60 I would enter :

foo.`clamp($F, 20, 60)`.obj.
