hi, I am looking for a way to specify every other point in a regular triangular mesh?...I tried culling but this only works with rectangular mesh...please help...Continue

"Since the input is a perfect grid of points (is this always the case?) one simple approach would be to assign a value to each point which indicates how much it deviates from the elevation implied by its neighbours. If it's exactly at the…"

pointcloud(polygon) reduction

Hi,I have a long term problem...I am trying to make a terrain model which would be triangulated depending on the steepness or curvature of the landscape...for example places which are more complicated will be more populated with points or triangles and the ones closer to flat would have less of geometry...the best thing would be if the amount of the geometry could be overall also increased or decreased, depending on the needs...thank you for help...See More

Hannes Löschke replied to Jiri Tomicek's discussion central point
"How would that point be defined by density? Do you some sort of gravitational center? That would just be the average of all the points."

understanding vector fields

Hi, I am not very sure if I understand the exact difference of two vector field types that I am working on...the first one is simply based on the attraction curve showing the vectors at specific points...the other one is already an interpolated vector field showing only the resultant vectors...are these two completely different results or can they be combined? for instance, would it be possible to show a vector at a specific point in the interpolation model, like in the first example?thank you…See More

Millipede

Millipede is a structural analysis and optimization component for grasshopper. It allows for very fast linear elastic analysis of frame and shell elements in 3d, 2d plate elements for in plane forces, and 3d volumetric elements. All systems can be optimized using built in topology optimization methods and have their results extracted and visualized in a variety of ways.In addition millipede implements a few basic geometric features [extraction of iso surface meshes from volumetric scalar fields…See More
