1. ## My experiments, with source files

nice implementation, after thomas help, i got these triangle forms, his research is quite nice about quantization Thomas Dotheij R'n'D November 2016 : Vector Quantization computer vision seams pretty interesting
2. ## Houdini 16 Wishlist

casting user defined functions from one wrangler to another wrangler,
3. ## Creating a Subway network in VEX

tutorialminmax.hip
4. ## Creating a Subway network in VEX

i dont get it why you are using closestpoint, you want to find the bluest/greenest color value for each sector and store the bluest/greenest from each sector to a list right ?
5. ## Creating a Subway network in VEX

i am sorry i answered in affect when i saw the picture, but "seek" is not defined, int extreme[] = pcfind(0, "Cd", seek, 2, 1); is maybe what you are looking for
6. ## Creating a Subway network in VEX

you could sort your points by their polar angle and range them for exemple 300-330 is blue "converting between polar and cartesian coordinates" https://en.wikipedia.org/wiki/Polar_coordinate_system

8. ## Divergent noise

you can use https://www.orbolt.com/asset/animatrix::cameraFrustum::1.00 from animatrix points from volume, and create a vector field (@P - cameraposition )
9. ## lightning effect round an object (eg torus)

i guess you mean ? http://www.orbolt.com/asset/joz::jr_lighting
10. ## [novice] Adding gravity to geo at the Object level

yeah sure, tough its clear, when the other forces are not affecting the torsus in dop, thanks for the heads up!
11. ## [novice] Adding gravity to geo at the Object level

you can use simple euler integration. http://www.tokeru.com/cgwiki/index.php?title=The_solver_sop

fett!
13. ## FLIP smorganic/sheeter effect?

thats very kind! thanks for sharing it !
14. ## How to creat subdivision pattern ?

i am also working on some custom subdivisions @f1 you are really a sensei!

code ?
16. ## Diagrid

can you post some ref pictures, you can triangulate the mesh for your needs, and use the wireframe sop
17. ## [Arnold] Porting Osl,Glsl into ArnoldShaderNetwork with Vex

i am trying to create custom shaders for arnold, and i really hate c++! it works fine with sopcontext and "user data", but i am a little bit lost with creating the right operator type and using a vex script to extend the arnoldvopnet, has some one tried it so far, or is it even possible to avoid c++ code and create custom shaders for arnold ? Thank you in advance
18. ## Move Points

"linear interpolation" linear.hipnc

stunning !
20. ## Calculate Curl on a grid sop using attrwrangle sop

you get the curl if you take the cross product from your vector and gradient, if you want compute the gradient from a grid in vex, you have a ode with 2 components x,y and you can compute the gradient for each component, but if you have 3 components and they depending from eachother like a vectorfield, you can use a gradient descent (jacobian) algorithm it does the exact same thing what sensei pusat described to compute the partial deriative, to get the gradient for a vectorfield with x,y,z, its my understanding i can be wrong
21. ## How to enter my code presets in a Wrangle ?

edit parameter interface, "Vexexpression", parameter description "Menu", "vexpressionmenu" is under Houdini 15.5.480\houdini\python2.7libs

24. ## Python install version?

i used anaconda and created a python2 environment for houdini, http://conda.pydata.org/docs/using/envs.html but the download libraries were for py 2.7.11 some of the scipy functions working, some of them dont, scikit-learn crashes can i update the pre-installed libraries ? or pointing to a other "lib/site-packages" path
25. ## Python install version?

i dont get it anyway, how to use the python libraries in houdini,
