which I understand analyses only 2 octave bands (500 Hz and 2 kHz) instead of the 8 bands (for which the STI component requires background noise.)
Or have I misunderstood this metric and the three values mean something else?
For reference / a minimal definition I have the open office example (gha and 3dm attached) which includes 20 receivers and the sti results show three values for each (see the image).
Thanks in advance Roly…
o a random name the component just uses 3 of the 5 total beams (img 1), and I don't know why.
I tried to change some parameters and I found that if I name the beams with the id 1 everything works (img 2). Am I missing something or is it just a bug?
Thank you for help…
cross a doubly curved surface. The beams are also cambered to make them more stable, so they weave under and over the surface, which is why the pattern can be hard to see in the photo. Our process was as follows:
Essentially the stages are:
1. Project a pattern onto a doubly curved surface.
2. Smooth the pattern over the surface with dynamic relaxation (we used this: http://parametricmodel.com/DynamicRelaxation-fixednumberoftimes/12.html)
3. Rotate each line of the pattern so it becomes reciprocal. This is probably the hardest step as you want everything to be straight and you want all the lines to terminate cleanly.
4. Turn that pattern into beams & construction drawings.

mmed triangular NURBS surface. However, please notice that the parametrization will be small in the area of the two coincident vertices.
I'm attaching a very simple example (Gh 0.6.0059)
I hope this is helpful,

country and in particular London. Point clouds are available online and perhaps there could be a way that they inform the building heights. I have been exploring the following process:
1. the mesh produced with the point clouds. Rather accurate but using the delaunay meshing, the shapes are very rough and dented.
2. I populate the mesh on GH.
3. Using Gismo 2D shapes, I test for point inclusion for each shape and find the highest point. Its height (z) extrudes the 2D shape.
4. The result is very convenient in many cases, though it is not easy to control which shape is extruded to the eighest point as larger polygons could contain smaller ones.
I am still looking for a way to filter more the OSM shape component so that the 2D shapes are strictly buildings.Although the LIDAR files are rather very heavy, perhaps there would be an automated way to query the databases with GISMO.Food for thoughts.

, toggle component change corresponded one to each item automatically.
I guess this result would be something like this
is it possible? if so, please tell me!!!! thanks a million in advance!!!!!!!!…
