generative modeling for Rhino
is it possible to create a flexible domain for the image sampler? or would that requiore a rewirering of the image sample component as it is?
it is because I have two series hooked up to a pointgrid, where I would like to change the spacing of the points, but if I do so then I change the domain for the image sampler, at the image will not scale....
I have attached the file and image...
Are you sure that will work for points? you know since the image sampler ask for points not a numerical domain?
Because the problem is not to remap/reparametrize a numercial domain, but to make the working domain of the image sampler to scale as you scale the spacing between your points... so in a sense the problem is not so much on how to deal with domains, but how to make the image smapler understand when you change the size/domain/whatever you want to call it for your point grid...
ahhh okay... thank you very much... This is just my first time to mess around with the image smapler component, and I am having a little trouble wrapping my head around it...
I find the best way to use the image sampler first time around is to:
1) insert a Picture Frame of your chosen image into Rhino.
2) Reference Surface from Rhino.
3) Reparameterise the Referenced Surface.
4) Use the SDivide Component to generate you Points.
5) Use the UV output of the SDivide component
6) Have the Image sampler Domain as 0 to 1.
This approach allows you to apply your "Manipulation" directly to the SDivide points so that you can see what is happening in the Rhino Document on top of your chosen image.. This quickly highlights any irregular or unexpected behaviour.
cool thanks for the tip!
hi, do you have any idea on how to map a image sampler onto a 3d surface? i have a points based on centrepoints of trangles. I want to use these centre points to be based on a image sampler from ecotect to determine the radius of the circle. My surface however is 3d.
i figured it out if anybody is interested. I used [Surface CP] obtain the UV values based on the inputs of Points and Surface. The uv values is then fed into image sampler. The circles created then can be adjusted to the normal of the surface through [evaluate surface] component. Oh, and ensure that the domain of the image sampler has the same values as the grid size. Or, you can just change the domain as what danny did above. =)
