for someone who may have the same question
the solution is to check the Use VEX and then simply type in "wind = @N"
seriously some of the parameters are so ambiguous for accessing them,
if you try to copy & paste the relative parameters like Wind Velocity and Air Resistance,
you'll only get the value instead of the reference.

even if it's difficult to maintain and provide the samples of the usage for each nodes,
the documents could at least shows up all the local variables name.

Houdini Indie and Apprentice » PopWind Set Velocity by Normal?

Hi I'm trying to simulate a simple wind environment with Popwind,
the pop works fine with any number input for velocity,
but when I tried to multiply it with local variables like $NX and $NZ
I didn't get the result I was hoping for.
Please help me if there something I was missing.
thanks in advance :]

looks like its working to me. You need to render it with mantra or karma or some other renderer to see it correctly. the opengl view is just so you can vaguely see something while you work. alpha compositing doesn't work how you expect it the scene viewer. Partial alpha makes the color blend with the background, not accumulate with other geometry.
Hi jsmack, thanks for your explanation,
I'll try getting the correct result on rendering then :]

Hi, I'm trying to set the opacity to the edges
so that I can see through the grid patterns on the ground.
I tried to set the @Alpha value,
but neither point nor primitive wrangles work;
Is there an SOP node or how can I set the opacity value in VEX?
thanks in advance;

Houdini Indie and Apprentice » How to create a double precision parameter in VEX or by a node

tamte
first thing you need to do is make sure your Spreadsheet is showing full precision (View/Full Precision)
and then you should see the correct answer (instead of rounded number) even with default 32bit single precision float
then if you still need your floats to be double precision, set Bindings/VEX Precision to 64 bit
Hi, thank you for the reply
I haven't noticed I can tweak the settings in Spreadsheet views,
thanks it really help.

I investigated something similar recently:
https://www.tokeru.com/cgwiki/HoudiniVex#itoa_and_64_bit_precision_limits [www.tokeru.com]
"The fix required to swap to 64 bits, which you can do on a wrangle by going to the bindings tab, and changing 'VEX Precision' to 64-bit."
Hi, thanks for your help,
the website is a good learning source for a newbie like me
I changed the VEX Precision to 64-bit and now it works :]

Hi, I'm new to HE
trying to convert Calendar date to Jdate
but since the number is over 7 digits,
I can't get the correct results via VEX like coding in other language,
so How can I create a double value via scripting in Houdini?
or is there a node to handle double attribute in obj Network?
Thanks in advance :[

Hi, I just started learning HE,
and some of my learning material were based on 18 or early 19,
since I'm using 19.5 indie,
I don't know whether there are difference by versions,
or those nodes are simply disabled and cannot use anymore?
https://www.sidefx.com/docs/houdini/nodes/sop/partition.html [www.sidefx.com]
https://www.sidefx.com/docs/houdini/nodes/sop/copy.html [www.sidefx.com]
by the way,
why is my looks so different than the source?
How can I settle this so my nodes will be exactly the same as the tutorials？
Thanks in advance.
