Technical Discussion » How divide ngon with specific points ?

How divide the polygon 1 between 10 to 43 and 8 to 42 ?
What i want is 3 rectangular polygons (2-6-10-43; 10-8-42-43 ; 8-5-1-42)

If i use divide node, i get 4 polygons (2-6-10 ; 2-10-8-43 ; 8-5-42-43 ; 1-5-42)
And polysplit node doesn't work directly on points.

I know i can delete polygon 1 and make 3 polygons with an Add node, but i want to know if there is a way to do it directly.

Thanks for replies

Solved.
In fact the problem is if you exclude any light on a geometry, instances lights will be exclude too…

I have a setup of instanced lights and all works fine except the reflection of lights on geometry. My instances are in Full point Instancing.

Obviously, the light used for instance object is reflected fine on my geo.

Any idea ?

Thanks for reply.

Hi twod,

Did you test the new Quadro K5000 ? Under Linux ? It would be useful to have a forum section with some graphic cards tested hardware.

tamte
you simply assign some keywords to lights Categories parameter

then to any object you can add Light Selection parameter and specify keywords there as well

as a result that object will be illuminated just with lights containing any of the keywords on object

Thanks Tamte, it's a long time ago i try to use categories…

Houdini Lounge » how to make the crown shape splash?

Thank you for suggestion.
I already watched it though, and I think it is more like for random rough looking splashes..

I would say not so random because the splashes direction/velocity/alpha/color are based on FLIP fluid simulation.

i exported an ifd sequence without specify the output image.
So by default is ‘ip’ and render in mplay interactively.

When i render in command line with mantra and the -o option, in mplay, the image is what i can excepted, the pic file is created, but is not readable at all, his size is 0 or 4 Ko….

I tested to export another ifd with a path in image output and the pic file is good.

If i can avoid to export again my sequence, it would be helpful

render with H12.0.683

Thanks for your help

HI

Playing again with point instancing, I wonder how to vary the scale of my instanced object independently in x,y,z ?
Pscale works only for uniform scaling …

Any idea ?

Check in the first page of this thread, the examples from halfdan

There is a cvex transform example

Hi fsimerey,nice work any chance you can make the image smaller currently it fills my browser . Feel free to show an example of how you did it or any hip files for others.

Sorry for time to reply, i was very busy…
And i resized the picture !! Sorry for that.

vbk!!!
very nice work, fsimerey
I woud love to check an .hip file if possible : I am trying to make the same kind of stuff so …

My file is very simple given that all characters are at this time, without animation. It will be the next step…

I have 3 attributes:
- pscale (for adjust size of characters)
- numcast (between 1 to 45, to identify characters)
value exp: ceil(rand($PT+1232654) * 45)
- instancefile (to get the geometry based on numcast)
value exp: $HIP/geo/public_europe/rocket_casual_bat_`point(“../attrib_numcast”, $PT, “numcast”, 0)`.bgeo

The only trick here is in foreach SOP by ‘Each Attribute Value’ to setup material with an override for ‘BaseColorMap’ based on numcast attribute to avoid oversize memory.

I can uplaod an hip file, but without characters geometry, it's not very helpful. But let me know.

P.S. vbk, si tu es sur Paris, on peut se rencontrer. Ca serait plus simple pour te passer des fichiers
