whitewater - generic questions

[cily]

A couple of version about the whitewater in H

 

PART A:

cached out the whitewater, I have the 3 group foam spray and bubbles, 

to see in viewport the result as in the dop lvl I'm running this wrangler

 

if (inpointgroup(0,'foam', @ptnum) == 1) {
    @Cd = {0,0,.5};
    }

if (inpointgroup(0,'bubbles', @ptnum) == 1) {
    @Cd = {.5,0,0};
    }

if (inpointgroup(0,'spray', @ptnum) == 1) {
    @Cd = {0,.5,0};    } 

folloved by a vop with lenght and fit to manage the luminance based on velocity, 

 

question

1) there are a faster way human friendly to have this result?

2) vex doesn't have elif statemnt?

 

PART B:

whitwater solver is an asset using pop Solver,

anyone tried to switch it in Flip? just to have more kernel structure of the 'fluid'. - other sw are using flip also for whitewater .

 

thanks

there is an else in vex, not no elif.

 

for a more straightforward approach, i would suggest you use the groups in the group field of a color sop (or three color sops) to set your colors.

 

you can also do "@group_XXX" to check ownership of a group.  so "if (@group_foam == 1)" can replace the whole "inpointgroup()" thing.

I believe Miles meant, there is an "else if" in vex.

 

This works,

if () {}

else if {}

I never use "inpointgroup", I would just do this:

 

if(@group_foam==1)@Cd={,,.5};

if(@group_bubbles==1)@Cd={.5,,0};

if(@group_spray==1)@Cd={,.5,.5};

 

sorry, just saw @fathom already posted that...

sho!

 

yeah, i figured the "if" was implied.
