s the "Surface Populating" definition: I manage to populate my geometry over the surface, but after I bake it, I have to delete the boxes that define my components limits as well! Is there any way of populating and baking only the chosen component, without having to delete the boxes afterwards?
Secondly:
Basically: I am trying to cover a surface with two types of components [ an open one and a closed one] , which will be proliferated over my tubular surface according to the main sunlight direction.
1. I introduce the surface component.
2. I use "Divide Interval2" in order to have division into U and V.
3. i generate the target boxes [ "surfaceBox"] .
4. I use "Isotrim" ( same intervals) and "BRepArea" to find centroid of each area.
5. My "Curve" component introduces sun angle, with its "End Points".
6. I use "Vector 2Pt" to specify sun-light direction.
7. I want to measure the angle between sun-light and the surface normals, at the position of each component; after generating the centre points, I need the normals of each centre point to get the surface's points' UV, and "Evaluate" the srf at points.
8."Angle" and "Vector" components: I use them in order to evaluate the angle between the sun direction and the srf.
9. I convert this angle to degree by using a "Function" [ to see if the angle is bigger from the max.angle or not...]
10. Function "x,y" gives me boolean data.
11. Data become "Dispatch"ed...
12. Two "Morph" components , each one linked to one part of the "Dispatch" data, generate "closed" and "open" components over the srf.
The result should have been different types of components, based on the surface's curvature, diraction and sun-light direction...
I do not understand where the mistake is in this definition...
Thx in advance1

cessary for Empety Branch??For example, I have a list of 59 line-like curve and 12 breps. I use the BCX component to show the intersection conditions .What I expect is, if they intersect somewhere, point(s) is dectected, if not ,a null item appears.But now empety branch appears.Then I found it's much harder to handle these empty branches than null items.For short, see picture below:
what I expect here is: {0;0;0},{0;0;1},{0;0;2},and otner empty branches contains one null item each..And I cant insert a null into an empty branch..So my wish this time is Empty Branch would be canceled or at lest reconsidered..what do you think??hope someone can help me out~

a given with the third set of information (at the 6th minute). From that, it will then match - for the same exact boats - the speed data given at the 4th minute. Finally it will do a matched subtraction of V(4th) from V(6th) for each boat. Those numbers - whether then scaled up / down or somehow manipulated - will act as the Z dimension which will create the topology. Since V2 - V1 can have a minus value, the overall topology will be a mix of mountains and icebergs this time.
Perhaps to be more accurate, we could divide V2-V1 by 120 and let the topology show the change in speed in a second within that two minutes; the XY coordinates belonging to the latter position of the ships, not the first.
Your definition as you say helps for the linear drawing as it continues from it's stopped. I used that in the current sketch as well for again doing the same thing.However when, I tried to use it for what I am trying to do with the acceleration thing, the result was different. I will try to explain this again;
Let's say that until this point 6 sets of data has arrived - so 12 minutes has passed -. Within that 6 sets, the number of of boats for each one differ as not all of them are able to send data every time. Let's assume in total there are 25 boats and 18 of them have always managed to send data in those 12 minutes. So 18 from the beginning until the end, and finally let's say the remaining 7 of them only could manage to come into the picture at the 4th set of data (so 4,5 and 6).
Now, if I were to build a topology of acceleration for the 6th minute which would mean that I would have to subtract V(4th minute) from V(6th minute) of all 18 vessels, I would need index 2 and 1 from all the branches. If I do this only after 6 minutes has passed from the beginning it would probably work, however if I do it later like at the 12th minute, it does not.
And the very reason for that is when the remaining 7 join the crowd at the 8th minute they obtain an index number of 0, and then 1, and then 2 - at the 12th minute. Because of that when I try to match the V2-V1s with Coordinates on the Unary Force component, while there are 18 sets of coordinates, there are 25 different speed values.
Of course this is quite a simplified scenario and perhaps your vessel matching could solve this specific one but there are cases where its more complicated and random.
I do still want to show vessels' position in a specific time with such pipes you have suggested, but I am trying to construct a collective model, in its simplest form being equal to pipes + topology
For the time thing, what I meant was in this version when you click play the mountains just keep on rising and the topology is constantly deformed. I was wondering if we can set up a timer so that it runs the physics engine for couple of seconds and then freezes the topology as it is. Otherwise I would have to press pause manually everytime, which is not that big of a deal tbh, just for the accuracy sake it would be good to run the engine for the same interval for each model.
All the best,

entations (0, 30, 60, ..).
I use a simple definition with native components to extract this information from the epw file. However, I run into some 'trouble'.
There seem to be a lot of 0 values in the wind velocities. Most of these 0 values seem to be associated with the 0 direction (north direction is common in this weather file, i.e. Singapore, but I doubt it is so many 0s).
I then proceeded to cull all the hours with 0 wind velocity and did the averaging over all the remaining hours (around 7100 for this weather file). However, I still get a bit of odd results that don't coincide with other data I have for the area. For example, average wind velocity in the north seems to be 1.12m/s while officially Singapore reports 2.1m/s. More discrepancies arise in the frequencies of the wind directions (the hours of each direction per year divided by total hours) from publically available data.
Anyways, I don't want to tire you with so many specifics. The question to the forum is if anyone has used .epw files to collect wind data before and if we believe they are dependable for such calculations? If not, do you have any idea on where I could find open wind data of good quality?
Thank you very much in advance.
Kind regards,
Theodore.
P.S.: Will be adding the definition once I'm in the office, even though it is quite straightforward.…
E. With the Servo library you can control up to 12 servo motors using an Arduino Uno (there is one limitation in that the servo library disables PWM capabilities on pins 9 and 10). You can find out more about how the servo library works here: http://arduino.cc/en/Reference/Servo
The biggest issue in controlling more servo motors is the amount of power you need to supply to each motor. It's likely that a single Arduino powered directly from the USB cable will be able to supply enough power to control more than 2 motors. You will likely need to provide an external power supply that has the proper voltage and amperage specs to properly power your motors. I don't know which servos your using (and how many) but you should look at the datasheet and determine your power requirements. Adafruit sells a pretty beefy regulated (switching) power supply which may work for your application (http://www.adafruit.com/products/658). This one will supply up to 10 Amps of current and 5V regulated voltage. Does this help?

y I have 25 surfaces, and so 25 directions. Everything fine.
But I wanted to have 12 go in one direction and 13 go in the other direction.
What I did was to create both negative and positive directions, having 50 directions for 25 surfaces. So I then proceeded to weave these directions, and split the list in 2.
To the left is what I achieved in grasshopper, to the right is the desired result.
As you can see the first story of prisms is extruded in the wrong direction.
Thanks for any insight.…
