2D Point Cloud Density

Hi Everyone,

I'm looking for some help to create point cloud density diagrams on a 2D plane. I have found something similar on the foruc but I cant seem to recreate the script properly!

Basically I want to have a 2d surface where its brighter in the areas that there are more points (some points are also "over each other"). I've attached the script Im currnetly working with, as well as some examples of what I'm looking to achieve. Hope someone can help!

There is another way.... follow this...

Slider objects have the ability to output animated frames.

You can place a dummy slider on the canvas and follow the steps in the image posted above. (The output is bmp, but if you're fine with photoshop shouldn't be to much hassle to select and alpha mask it if you need transparency in .png

Image 1, place the slider and set it up by double clicking on it. You want as few frames as possible. (i.e.3)

Image 2, access the animate

Image 3, export animation, set filepath, setting the resolution, line up your view port.

Some people have produced plugins that can bake from grasshopper with colours, (but they since your file uses the blurry dots object, this bakes as a sphere in rhino since it doesn't support blurry dots)

rhino viewport method....

advantage - png and transparency supported

disadvantage - sizing the viewport big enough to capture a good resolution

Printing Method.

Advantage - very large scales can be achieved, as well as transparency

Disadvantage - file format limited to whatever printers you have installed. (There are png printers out there). Possibly too large which means you need to increase line thicknesses either in the layer palette or in the print overrides

You can do it from the rhino viewport, or rhino print.
(Baking is only to fix the file as native rhino 3d geometry.)

Thanks for all of these options!

I was in a bit of a rush so just ended up screen shoting them in the end, but it did he trick and my crit went well! I'll defiantly have a go at these methods for the final thing though!

Thanks again
