## Volume toon shader

Play with this, sorry for errors I use Houdini 16.5. You can implement this on the explosion toon_v15.zip toon_smoke_final.hip www.linkedin.com/pulse/toon-explosion-houdini-seyed-morteza-kamali?trk=portfolio_article-card_title

## looping over an integer array with itoa()

why not just taking integer number then? if user enters 3, one group will be 0 1 2 and another 3 4 5 ir in another words if you have integer paramerer "n" then one group field will be: 0-`ch("n")-1` and another: `ch("n")`-`ch("n")*2-1`

## looping over an integer array with itoa()

while I don't completely understand what you are going for, but this s@integertostring = itoa(s@mystrArray[i]); should probably be this, as you aferall want to convert int to string s@integertostring = itoa(i@cleanArray[i]); but I doubt it will help your code as you are clearly dealing with strings and want output as a string not string array, what exactly are you trying to do? Why would someone enter only sequential 0 1 2 3, what if user enters 0 3 4 6? what would you expect the rest to be? 1 2 5 7? what if there is not 8 points in the geo? sounds like too many assumptions usually you want to use groups for this, you pick your points as group A and then one copy uses group A and another !A if however you still want to pursue VEX then have a look at functions like split() and join() to avoid unnecesary code, also you may want to use variables instead of attribute bindings unless you want the values to be atually output into an attribute

## Fuel Based Rocket Launch

I made an attempt at "upresing" this fuel based rocket launch. Treating the original file as the a low resolution simulation does allow me to enable OpenCL. The uprezed version is on the right. A 500,000 voxel low res source drives a 4,000,000 voxel upres. ap_upres_smoke_pyro_setup_032520.hiplc

## Q: Building Gas Fields, Masks, Custom Forces

Hi, the mentioned masterclass is probably this: https://vimeo.com/42988999 I also like this tutorial: https://vimeo.com/119694897 Matt Estela has great tutorials: http://www.tokeru.com/cgwiki/index.php?title=HoudiniDops# http://www.tokeru.com/cgwiki/index.php?title=Smoke_and_Pyro I don't know if there is any new video tutorial, which describes the low-level principles. I learn by digging into the "shelf" solutions https://forums.odforce.net/topic/41800-gas-analysis/?do=findComment&comment=199863 https://forums.odforce.net/topic/42101-how-do-pyro-collisions-work/?do=findComment&comment=201007 Btw, when I am digging, I use this script "Find all parms referencing this parm". http://lex.ikoon.cz/find-all-parms-referencing-this-parm/ Here is an attachment, microsolvers_dev.rar with lots of experiments, just for an inspiration. Unfortunately lots of it is outdated (it is from the year 2011) https://forums.odforce.net/topic/13748-learning-microsolvers/?do=findComment&comment=101666

## Make Curve In VEX

please take a look at the attached file. it´s an example how you could create bezier curves with arbitrary degree and another one relying on beziers in hermite form since you wrote about blending curves... petz curves_vex.hipnc
