A: Who created it? / Copyright?
B: Anyone have a larger resolution copy of this image (or a vector so I can do a large resize).
Long and short - I'm an artist and I'd like to make a quilt out of that image. I need a decent resolution copy of it so I can do a huge resize and get a 76" x 80" crop out of it. I've tried resizing it in Photoshop, but by the time it's large enough, the quality has dropped below what is usable for my needs.
Thanks in advance! I totally understand I'm relying on the kindness of strangers here. (Also if this is inappropriate to post - please delete. Thank you)

e section which wont recompute with owner.expiresolution(true). Am I missing something ? I cannot declare buttons and form and all that stuff in run script, cause it doesnt accept withevents property. My idea is to recompute all the script component stuff...
This is my code :
Private Sub RunScript(ByVal x As Object, ByVal y As Object, ByRef A As Object)
If x = True Then frm.Controls.Add(b1) t1.location = p0 frm.Controls.add(t1) frm.show a = zmienna Else frm.Dispose End If
End Sub
'<Custom additional code> Dim frm As New system.windows.Forms.Form WithEvents b1 As New system.Windows.Forms.Button WithEvents t1 As New system.Windows.Forms.TextBox Dim p0 As New system.Drawing.Point(30, 30) Dim zmienna As String
Private Sub b1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles b1.click
zmienna = t1.Text owner.ExpireSolution(True)
End Sub

(1) I have been exporting small sections of a larger model into Maya from Rhino as FBX. In Maya I rotate and scale the models (-90 in X, Scale XYZ 0.001). The Named Views are being saved, but do not have a successful import into the Maya model. They do not appear as in Rhino, and the problem is not solved by scaling or rotating the cameras.
(2) If I try going the other direction, the cameras exported from Maya as FBX are also not aligning with the model in Rhino as they are in Maya.. I will do my best to post some images of the problem and hope you can help.
error !!
This is what the named views look like
here I am trying to the other way with a good view from Maya
strange placement..
This is the best result I can achieve, after I scale the camera by 1000
Any Advice???
Thanks, Robert.

When you run the simualtion you will notice on the batch terminal that Daysim is also being called, so you may want to consider how Daysim uses Radiance files & data.
Regarding your current problem, I think you stumbled onto something weird and interesting.
Interior and exterior readings appear to differ by 40 in the best case scenarios. Even setting the transmittance to 1 yields similar results. I tried changing from cummulative sky to climate sky and got similar values. Changing the test points did nothing either.
I think, (yet I'm too lazy to prove this) that the difference in values stems from diffuse radiation over the sky dome.
If you delete everything except the glass you'll notice that interior values are like 80-90% of the exterior values (this seems like the expected behaviour with a transmittance of 1). So, if we consider that a vertical window, part of an opaque box, is receiving radiation from 25% of a sphere, as you start to inset the interior test points the radiation they receive will be a fraction of the 25%.
Let me try to explain this better...The exterior surface receives radiation from a section of a sphere calculated by 180degrees on the xy plane (let’s call this angle theta) and by 90degrees (let’s call this angle phi) in azimuthal elevation. If you integrate this over spherical coordinates (theta from 0 to pi; phi from 0 to pi/2) you will find that it comes to a quarter of a sphere. By comparison, the interior surface will not integrate theta from 0 to 180degrees,nor phi from 0 to 90degrees, instead it will be the subtended angle from the exterior surface as a function of their separation; the farther in you go the smaller the view of the outside.
If my hypothesis is correct there shouldn't be that much difference since the separation is only 10cms...the subtended angle would be like 170 instead of 180 for theta and 85 instead of 90 for phi...overall if you integrate both spherical areas there should only by a difference of 10%.
In conclusion, I believe the unexpected behaviour stems from the previous subtended angle thing. If direct radiation was the only factor the difference would be the aforementioned 10%, which suggests that an additional source of energy is also affected by this. Perhaps indirect and diffuse radiation from other areas of the sky dome.
I’m definitely intrigued on why this is happening. Please post if you figure it out.

Mauricio

TB of RAM. I think I'm going to start a GoFundMe campaign to buy one for myself :)
2- The server's cost is about $13 an hour. I get free access to supercomputer through my university and xsede.org because I earned an NSF Honorable mention last March, however, the supercomputers available through both resources are a little complicated for me to use, as opposed to the one available from amazon that has Microsoft server 2012 already installed.
3- I wanted to run 400 annual glare simulations for 400 different views.
4- I tried a to perform annual glare simulation for one view on my Dell XPS that has Intel Core i7-6700HQ processor and 16GB of system memory. The simulation took 2 hours to complete. Radiance parameter ab was set to 6.
5- I wanted to obtain the batch file for each view so I can run them on the server. So I used the fly component to run all 400 simulations and closed the cmd windows, that wasn't bad ( for me at least) because I asked my son to this job for me, he was just glad to help me :)
6- I created one batch file using this cmd command:
dir /s /b *.bat > runall.bat
This created a file with the path to each .bat file. I edited this file in Notepad++ to include the word "start" at the beginning of each line. This was done using the "find and replace" dialogue box.
7- I split my newly created batch file into 3 batch files, each one has about 130 file names and " start" before the file names.
8- installed radiance on my server
9- Ran the first batch file on the server, this started 130 cmd windows performing my simulations, CPU usage was anywhere between 90% to 100% and about 105 GB of RAMs were used.
10. It took about 5 hours to complete all 130 simulations, I expected to run all in 2 hours but can't complain because this would've taken about 260 hours to run on my laptop. After the simulations done I ran the second and then the third batch files ( total of about 15 hours).
11. I got 400 valid dgb files. Couldn't be happier!

he time to work with it.
the project is about facade strips which turns along height. the top angle is
parallel to the facade and the bottom is max. 90 degrees twisted, but the strips
should turn diffrently to achieve more dinamic look.
first i have tried to achieve this by calculating distance between the rotation angle from points of the grid and a single point.
then i have tried to ad some more effecting points and used the distance to the divided surface (the circles are just to control the area of effection):
i manually lofted it.
the result is a bit annoying becouse the points that effect the angle are always visible:
i have triend to solve this by drawing a line and divided it to recieve points along the bottom of the geometry. the result is not working properly:
Anyway,
there must be a better/smoother way to achieve this. i would like to effect the twist of the surfaces by distance to a spline, but im just lost. can you help me please?
the problems im encountering:
0- distance spline to grid to effect the angle
1- list of x/y coordinates and angle of rotation for each point of the grid
2- export points to excel
3- lofting lines in one direction only (x1, x2, x3...)
4- reduce the list data to 2 decimal (0,00)
5- maybe angle from radian to degrees
thx…

assume we want to format two numbers, one integer and a floating point value. The integer represents an index and it should appear inside square brackets, then we want the floating point number rounded to a maximum of 4 decimal places (but always using at least one decimal place, even if it's zero), and then, in parentheses a scientific notation representation using 8 decimal digits of the number.
So, assuming the index is 16 and the value is 47.280006208, what we are after is:
[16] 47.28 (4.72800062E+001)
To make this work, we need a formatting pattern that looks like:
[{0}] {1:0.0###} ({1:E8})
The square brackets, spaces and parenthesis are just part of the output, they have no meaning whilst formatting. Everything inside the curly brackets though will be replaced with a specific formatting of one of the values.
When using the Format component as shown above, the formatting pattern is just text data. The component knows that it is supposed to use the Format() function using the pattern text and whatever additional data is provided.
When you invoke the Format() method in an expression, you do need to make sure that the pattern is actually text:
So here the pattern needs to be encased in double quotes, otherwise it will be treated as code, rather than text.
You cannot use the formatting method in the internal expression of a number parameter, because this method returns text, whereas the number parameter is only capable of storing numbers. Any expression that you put into a number parameter had better return numbers as a result.…
ort and export from the images below and also from the HELP file of DB in attachments (Page 71: Importing Geometric Data; Page 78-80: Import 3 - D CAD Data). In their HELP file, they mention about "import geometric data".
However, regarding the input of schedules, loads, constructions and etc., DB normally uses "Component " and "Template" (Page 29: Templates And Components; Page 591: Templates; Page 533: Components). "Templates" are databases of typical generic data, including Activity templates, Construction templates, Glazing templates, Facade templates, HVAC templates, Location Templates, and etc. "Component " are databases of individual data items (e.g. a construction type, material, window pane).
Both "Component " and "Template" are allowed to be imported and exported by using "Import / Export library data" command (.ddf format - DB Database File; Page 734: Import Components/Templates, Export Components/Templates). DB also allows us to build up our own libraries of templates and components (Page 731: Library Management; Page 733: Template Library Management).
In order to import both geometric information and other information related to schedules, loads, constructions and etc. from GH to BD, we supposed the following two ways:
1. GH(HB+GB) --> gbXML (both geometric and "Component " and "Template" information) --> DB
This is the way we most prefer. We did see information related to schedules, loads, constructions encoded in the gbXML file generated by GB, but still do not know the reason why DB did not take this information (I also mentioned this in Q6 within the gh file). We assume this might because the gbXML file we create encodes the schedules based on a different template / schema than the one DB expects. We also post this question to the DB forum for help.
(http://www.designbuilder.co.uk/component/option,com_forum/Itemid,25/page,viewtopic/p,13755/#13755)
2. GH(HB+GB) --> gbXML (geometric information only) + .ddf ("Component " and "Template" information only) --> DB
If the first way doesn't work and DB only takes geometric information from the gbXML, then we might think of the other way - generating the .ddf files from GH(HB+GB) to pass the schedule, load and construction information to DB.
I was wondering if it is feasible for HB and GB to have this function? And what is your suggestion to achieve this?
In addition, we notice that DB can export XML files (not gbXML), so we are trying to figure out if DB also accepts / reads the XML file. If so, we might be able to convert the gbXML (with both geometric and schedule information) to XML. What do you think about that?
Thank you again for all your help!
Best,
Ding

n make it possible to Motivation generate
a variety of interesting objects, from abstract fractals to plant-like
branching structures, their modeling power is quite limited. A major
problem can be traced to the reduction of all lines to integer multiples
of the unit segment. As a result, even such a simple figure as an
isosceles right-angled triangle cannot be traced exactly, since the ratio
of its hypotenuse length to the length of a side is expressed by the irrational
number √2. Rational approximation of line length provides only
a limited solution, because the unit step must be the smallest common

1
√2
denominator of all line lengths in the modeled structure. Consequently,
the representation of a simple plant module, such as an internode, may
require a large number of symbols. The same argument applies to angles.
Problems become even more pronounced while simulating changes
to the modeled structure over time, since some growth functions cannot
be expressed conveniently using L-systems. Generally, it is difficult
1.10. Parametric L-systems 41
to capture continuous phenomena, since the obvious technique of discretizing
continuous values may require a large number of quantization
levels, yielding L-systems with hundreds of symbols and productions.
Consequently, model specification becomes difficult, and the mathematical
beauty of L-systems is lost.
In order to solve similar problems, Lindenmayer proposed that numerical
parameters be associated with L-system symbols [83]. He illustrated
this idea by referring to the continuous development of branching
structures and diffusion of chemical compounds in a nonbranching filament
of Anabaena catenula.
The following is an example of its application:
starting string: A
p1: A F(1)[+A][-A]
P2: F(s) F(s*R)
which I think is basically trying to say
F(s) = move forwar a step of length s > 0.
