grasshopper point cloud to surface

Units for this value are meters. What i want to do is to put random points on surface.

Features larger than this value will be maintained in the surface. It is pretty straight forward. A point cloud and 3D scanning library for Grasshopper. What would be the best method?

I have created a boundary of my site and where I require surface.

I put rhino file with two surfaces, you can try on them.I still have one doubt: how exactly would you define "better points on surface than freeform cloud"? Component Index Grasshopper Surface Freeform SrfGrid. This data will not exist, but even so it will require 64-bits of storage.I would like to manipulate the point cloud to be able to select ranges x,y,z data, to effectively cut slices through the model and get sections out of them. Inputs. Create a nurbs surface from a grid of points. It works fine in the example I …

Each point would have its color set by object - and it retains the color of the custom     previewer. In general it would be very useful to be able to manipulate real 3D surveys to use as context for sculpting apertures in buildings, visualizing in-city views accurately etc.. Each point must be stored separately, which greatly increases the memory footprint.

What would be an effective way for me to diagnose where effectively Memory is being used up?I see this thread is a bit old, but maybe this plugin helps for future pointcloud queries within gh! I am able to create a mesh but not a surface… Very easy and fast to use Please check your browser settings or contact your system administrator. The X,Y,Z data of the points is being read by reading a text file with the information in csv format.


What i want to do is to put random points on surface.First i tried with freeform cloud, but i dont want to have I would like to get some deffinition with random points INsiDE surface,do you mean inside like "in" the volume enclosed by the surface or like "on" the thin skin of the surface?It's a geometric solution to random points ON any surface.Hmm.. i tried it but it wont work??

More likely 28 bytes as colours are probably stored as 32-bit integers, allowing for an unused alpha channel.28 * 800,000 equals roughly 22 megabytes, which is Grasshopper stores points as instances of classes, so on 64-bit systems it actually takes 64+64+3*8 = 152 bytes per point*, which adds up to 122MB, still way less than 9GB.

What exactly are you trying to achieve?I want to create points on surface for voronoi diagram.But all definitions for points that i tryied create voronoi that is I want to offset lines so i will get surface for extrude.The solution I gave will result in some unclosed curves, here is a way to get correct curves:(If you don't need exact offsets, scaling and reproject curves should work well enough)I want to offset lines of voronoi, and than to trim "holes" I think there is problem with offset, i dont know if there is some other solution, because this make some parts with no offset.I read on some deffinitions, where points follow curvature (number of points) of surface or area of surface...but i couldnt find deffinitions.use evaluate surface with reparameterize option and domains between 0 to 1 like this:Please check your browser settings or contact your system administrator.I want to get points that will create voronoi less stretched and with "

The x,y information are real world coordinates so a gps point of a person inside this particular space would appear referenced as a dot. But I am looking into ways of manipulating all this data directly inside grasshopper.

You just need a surface that has more control points, right now you’re using a surface that has only control points in the corners. Rebuild the surface with Rhino rebuild command, make the number of control points higher. Ideas/suggestions are more then welcome.- How can you bake these points with the color information stored with the point?

But if this is not possible I can always reduce the extents of the observable space. Adjust this value to set the resolution (grid size) for processing ground surface points from the point cloud data.

This makes most sense on a macro space like a 1km^2. First i tried with freeform cloud, but i dont want to have groups of points that stick to edge of surface. Create a nurbs surface from a grid of points. This library's primary purpose is to add the point cloud functionality already apparent in Rhinoceros 5 to Grasshopper, with the ambition of treating point clouds as another useful data type, rather than an exotic type. What is the best way to handle point clouds with Grasshopper/Rhino. Hi Everyone, I am trying to create a surface using point cloud information of topography.

I would like to get some deffinition with random points INsiDE surface, or some witch have better deployed points. Surface From Points.
