Vex SOP

(I am new to Houdini.Please bear with my lack of technical knowledge of Houdini)

How does the velocity attribute work in vex?

I mean for testing it, i created a new SOP type in vex.

In the vex code i wrote the following

sop

sop1()

{

v={1,1,1};

}

After compiling it succesfully,i saved the otl file.

Then i dropped this sop in the network view and connected a line to its input and activated the sop.

The line is still at rest.

Nothing happens.What did i assign the velocity to? Where is the action?

Well you've given it a velocity attribute, but that doesn't mean it's going to move along the velocity path.

You need to stick it in a solver to do that...

You could test it with a sop solver (think it's just called "solver" in SOPs now) and add the velocity to the position every frame...

hi ,

#pragma label velo VELO

sop addVelo_vex( vector velo = { 0, 0, 0 } )
{
v = velo;
}
[/CODE]
