Emu – emil poulsen. Emu is an interactive structural analysis and form-finding tool based on a 6DOF (6 degrees of freedom) formulation of the dynamic relaxation method allowing engineers and designers to run bi-axial bending and torsion simulations in the parametric environment of Grasshopper3d.

It is aimed to be used in early design stages but yet giving real structural feedback. Emu was developed as part of a Master’s thesis in Structural Engineering and Building Technology at Chalmers University of Technology, with the aim of simulating the very non-linear process of elastic gridshell erection. The thesis can be found here. Other useful links:EXAMPLES, TUTORIALS AND WIKIMASTER’S THESISGRASSHOPPER3D GROUPMCNEEL DISCOURSE CATEGORYRELEASE LOG AND OLDER VERSIONS.

Tutorial 3 - Populate Surface. Introduction The Result of this tutorial A strong feature of Grasshopper is it's ability to populate surfaces.

Tutorial 3 - Populate Surface

In this tutorial we will populate a double curved surface with structural triangles. At first we will start making the component, which we will then use to populate the surface. The Design Before we start building the grasshopper model we should determine some of its basic properties. These variables/parameters could include: number of triangles in both directions open/closed specific shape variations (round corners, etc.) In this tutorial we will try to keep it simple, so we skip the complicating variables (for now). Step 1 - Starting the grasshopper model Create a surface First of all we need to define the triangles.

The size of the surface does not matter that much, but it is easiest to make it more or less the estimated size of the final triangles that will make the surface.

Local variations of the density of a random point distribution. Hi everybody!

local variations of the density of a random point distribution

Sorry to bother you with such a simple issue, but I can't figure out how to create a random distribution of points which local density would be based on some sort of "mapping"... For example: I wish to populate a rectangle with some random points, but I need them to be more dense at the base of the rectangle and then linearly getting more and more sparse towards the top. This is how I worked it around: 1) first I have created a triangular prism, 2) then I've populated its volume with some random points 3) and finally I've projected them on the plane I'm wishing to populate.

But I don't really like the final result since the points are not as nicely spaced as if they were produced by the "Populate 2d" command. Do you have any better idea? The best thing would be to be able to put a grayscale bitmap underneath and use it as a "density map"... Here you have the .gh file I made: Thank you very very much for the help! By the way:
