Softimage|XSI to SideFX Houdini
Posted: 10 Oct 2016, 14:22
Hey there!
As there is some discussion on the soft list about this, I´ll start a specific thread where people can add their knowledge on transfer Softimage knowledge/workflows over to Houdini. Maybe start with some explanation acronyms (Chris Marshall on the list asked about) that sound pretty cryptic at first. I´ll try to find some similarities to Softimage:
BSDF = "bidirectional scattering distribution function"...controls how light reflects off a surface
PBR = Physically based rendering
VEX = Vector Expressions ..the internal Houdini Language, so to say
VOP = VEX Operators ..some ICE like subnetworks, where you can manipulate all kinds of fetched data
SOP = Surface Operators ..means operators, that deal with all kinds of surfaces (poylgons, nurbs etc.) and manipulates them
VOP SOP = Vector Operators - Surface Operators.. networks that allows to work on a surface in a node based way like mentioned in the VOP
SHOP = Shader Operators ..a network where you can build and manipulate data for shading (render tree..)
ROP = Render Operator ..operators which deal with all kinds of rendering such as image calculation but also caching (geo or points etc.) stuff to disk
DOP = Dynamic Operators ..subnets that contains dynamic stuff like all kind of simulation (RBDs, Cloth, Particles, Flips and so on..)
AutoDOPNetwork = Automatically generated Dynamic Operators Network
CHOP = Channel Operators ..basically everything that has to do with fcurves and animation and stuff..
POPObject = Particle Operators ..a node that creates and manipulates particles
HDA = Houdini Digial Asset ..one way to store and share ready to use networks and import them into Houdini. A little like a mixture of an "emdl" and "ICE compound(s)" in Softimage
COP = Compositing Operators ..a compositing network inside of Houdini
Please correct me and/or add stuff ;)
cheers,
oli
