algorithmic modeling for Rhino

using the image sampler the height of a grid of points was transformed on the Z these points were then machined as a drill cycle using a v-groove bit, By using the v-groove bit the diameter and depth of cut became directly related and made for a simple process.

maybe .1 for max depth on a .5 inch sheet

thx!
I have made it , but i didnt use a cull ( which I guess deletes the highest point), what do you think was your maximum depth of milling in mm? This is just a great tool! I hope I can get one milled at my job, I ll send you pictures if I do
keep it up

It does relate to size but it's size in rhino working units. For example, you can keep your domain on the image from 0-1 and then you can feed in a range of numbers with a domain from 0-1 and 10 steps into a point component to produce a grid with 121 points. If you transform those sampled points in Z you will have the output taking place between 0-1 working units in the X and Y. Based on this I just got my grid to be the size I needed for my final parts and then set the domain on the image accordingly.

i tried again last night, i got a couple question. when i double click on the image sampler , what settings do i need to put?
and about the ranges in the definition, do the x and y range correspond to the size in pixel of the image? (does it matter)?
i put my image in black and white bitmap ( tide option in the right click menu of the image sampler?).
is the multplication value (18.9) important?
whats the culling function?
thank you for your time

well it samples every point on a defined grid against the image and based on the value of the image at that point it stores a value. you can then pass along the value to control the radius of a circle or the height of a point in space (like the height field tool in rhino).

i have never used the image sampler, does it make every (black) pixel a point?

the cull allows me to extract just the points I plan on machining - so essentially it acts as a cropping tool
