Comment on: Topic 'Water and vegetation features in Honeybee': u list here. The question of whether you can model these features in the way that you envision depends largely on whether you can find suitable EnergyPlus objects in that web page. The swimming pool seems like it will be sufficient to model the water features but the vegetation may be a bit more complex and you might need to find a substitute. Since there are no Grasshopper components in Honeybee to model these things, you will have to add them to the HB EnergyPlus model using the additionalStrings_ input on the Openstudio or EnergyPlus components. Here is an example of how to add additional IDF text to a model in grasshopper: http://hydrashare.github.io/hydra/viewer?owner=chriswmackey&fork=hydra_2&id=Evaporative_Cooling_Tower&slide=0&scale=1&offset=0,0 This example is specifically for modeling an evaporative cooling tower, which could be a workaround for vegetation if you get the evaporation of the tower to match your anticipated evaporation from plants in the space (you might have to heavily schedule the cooling tower's use to do so). Here is another example of using custom IDF text to model a green roof: http://hydrashare.github.io/hydra/viewer?owner=chriswmackey&fork=hydra_2&id=Green_Roof_In_Energy_Model&slide=0&scale=1&offset=0,0 The only reason why I think this green roof might to be suitable to model your vegetation is that the E+ reference stresses that this vegetation is only intended for exterior surfaces like green roofs and not interior vegetation. It is also seemingly only intended to model low-lying vegetation and not vegetation from trees, which it seems you might have in your model. I'm very interested in hearing the answers to the unmet hours discussion as my my suggested workarounds for indoor vegetation are very hacky. -Chris…; Added by Chris Mackey to Ladybug Tools at 8:04am on August 3, 2016

Topic: New Firefly Build, Website, and More!: with the latest version of Grasshopper (0.9.0006). This release has a lot of new features including: an entirely re-written Firefly Firmata, multiple web-cam support, a new Load Image component, several new filters and effects, a re-written Pachube/Cosm component, and a Frequency Visualizer component. For more information about all the new features, be sure to check out the ReadMe text file included in the download. I've also been working on an entirely new website for firefly. Starting from the ground-up, I rebuilt the interface so it's more user-friendly and informative. I still have plans to incorporate other features in the site... so expect more new here in the future. But, for now I'd love to get your feedback on the new site http://www.fireflyexperiments.com Lastly, I've also been hard at work on a new Firefly User's Guide (called Interactive Prototyping). This manual is still a work-in-progress but it is intended to teach the basics of electronics (using an Arduino) as well as various digital/physical prototyping techniques to people new to the field. It introduces Arduino (including programming in the Arduino IDE) and runs through several different examples. It also features an introduction to Firefly and has many step-by-step tutorials to teach you the basics of how to use Firefly as an Interactive Prototyping Environment (IPE). I intend to add new chapters to this in the coming months (including chapters on computer vision and networking). But, I wanted to release it now to give people a basic understanding of the interface. Again, I look forward to your feedback.

Topic: Accessing Rhinocommon DisplayPipeline methods from another function: questions; I am at very early stages of learning Grasshopper and Rhino SDK. I am somewhat familiar with programming but mostly for web using Javascript and PHP. However, with the new Rhinocommon libraries out, there are really trace amounts of information regarding this new API. This place might actually be the most valuable resource since Grasshopper was completely rewritten against the new API. So here is a thing I really do not understand in Rhinocommon: Let's say I am building a plugin which involves a panel with a button. When I press the button, I want a sphere to be drawn. As far as I understand, I have to write a function which would create a sphere and draw in the viewport. I also assume that the drawing is handled by DisplayPipeline method DrawSphere(). So the function would look something like this (I am using c#): public static void AddSphere(Rhino.Display.DisplayPipeline doc) { Color color = Color.Bisque; Rhino.Geometry.Point3d center = new Rhino.Geometry.Point3d(0, 0, 0); const double radius = 5.0; Rhino.Geometry.Sphere sphere = new Rhino.Geometry.Sphere(center, radius); doc.DrawSphere(sphere, color); } Now, if I want to call that function from a button_click or, for the that matter, any other method, how do I call it? private void button1_Click(object sender, EventArgs e) { AddSphere(???); } Am I on the right track at all? Any help would be greatly appreciated.…; Added by Andrey Guskov at 8:14pm on January 16, 2013

Topic: Using Image Sampler - Example Script: e curve and uses the resulting surface/subdivisions to: 1. Smooth wall surface, varied via the Image Mapper 2. Segmented wall surface, varied via the Image Mapper 3. Populate the surface with spheres (with or without the "wall" surface) 4. Ribbed wall surface (Horizontal and / or Vertical) 5. Protrussions from the surface, driven by Image Sampler 6. Wall of Tubes, driven by Image Sampler 7. Gridded Web Surface The options have to be enabled/disabled to achieve various results, but the idea is that this script permits a variety of looks, all in one script. See attachments at bottom. I think this is a decent example file showing a variety of things that can be done using the Image Sampler Component in Grasshopper. This is a working version, so I am sure there are a lot better ways to achieve some of these effects. Hopefully, this will help some of you out and / or inspire some ew idea. In the script, there is a User Object I downloaded from digitalsubstance. It is a self contained point attractor cluster, super cool, super fun. Link to the site is below. http://digitalsubstance.wordpress.com/subcode/ If there is interest, I will update this post with an annotated version.

Topic: [New Development] Pollination for exploring multi-dimensional data: ssibilities for better data visualization. Pollination<Vis> in particular is designed for exploring multi-dimensional data. The idea of Pollination born at the AEC-TECH Hackathon last year. I want to thank all the team members for the great original work. Also many thanks to Kai Chang for developing ParallelCoordinates library for D3JS. Creating Pollination would be very very hard without his development. Here is a very short video that shows how you can interact with data and load your own files. As you can see in the video I added to components to Honeybee that helps you generate an structured .csv file from Grasshopper. You can also generate the files manually. The data doesn't need to be results of Honeybee or Ladybug. Feel free to use pollination for any other studies including your multi-dimensional optimization cases! OK! That's all I have for now. Check the webpage here and the source code on github. Enjoy! Mostapha PS: If you are interested in data visualization and multi-dimensional data then I strongly recommend you to watch this presentation by Kai. …; Added by Mostapha Sadeghipour Roudsari to Ladybug Tools at 5:06pm on February 22, 2015

Comment on: Topic 'Best language to learn for beginners and is it worth it?': guages I'd recommend all use the RhinoCommon SDK and thus all have access to the same functionality. How long would it take me to understand and write my own code? If you already know how to program, it probably won't take too long. If you're past the hurdle of what it means to declare and assign variables, how conditionals and loops work and what scope is, you've already rounded the hardest corner. Is it even worth it? That really depends. "Learn programming" is clearly not blanket good advice. Most people out there do not have to learn programming to be happy with their lives and successful in their careers. For some people it can make a small difference, and for a few people it can make a huge difference. If you feel you're in the 'some' category then this is indeed a question you have to answer. Note that the investment for learning programming is a continuous process. Unless you keep up your skills and learn about new stuff that becomes available, you'll lose the ability to write successful code over time. Where do I start? Step 1 is to answer the previous question. It is unlikely that anyone besides yourself can answer it, but you can start by making a list of things you do manually now that may be programmable. Then make a list of the things you are unable to do now but which you might be able to do with programming. If while looking at these lists your reaction is: "meh", the answer is probably no. Step 2 is to pick a language. This is again a very personal thing; there's no wrong answer, because there's no right answer. Step 3 is to start learning this language. My experience is that the best way to learn a programming language is to try and solve a real problem that you understand very well. If the problem statement is nebulous or poorly understood, you'll be learning two things and that's a recipe for unnecessary frustration. Here are my thoughts on language: Python: I don't use Python myself, I can sort of read it while moving my lips. I don't particularly like Python though. The indentation sensitiveness stresses me out, and I find the lack of type-safety disturbing. However it is a good language for mathematical/scientific programs. There are lots of additional code libraries you can easily import that will ease the development of mathematically intense algorithms. C#: I like C# very much, but it does suffer from geekerosis. A lot of the keywords used in the language are not self-explanatory (abstract, sealed, virtual). For me this is no longer a problem as I've memorised what they all mean. C# is designed to be an efficient language to write, rather than an easy one to learn. The great thing about C# though is that there's a huge amount of material out there for learning it. It is one of the most popular, mature and modern languages you can hope to pick. VB: I learned VBScript as my first language, and then moved on to VB5, VB6 and VB.NET. It is somewhat more friendly than C#, and functionally it is almost identical. The switch from VB to C# is reasonably low-threshold and there are excellent tools for translating VB code to C# and vice versa. Since you already know some Python, it probably makes the most sense to continue on that path. If you want to switch, C# is more like Python than VB, so C# would be my next suggestion. As for where to get information... you have 4 major options when developing code for Rhino. If it's a question about the language itself, StackOverflow is a great resource. It can be a pretty hostile place for beginner questions, but I find that mostly the questions I'm asking have been asked already and the answers on SO tend to be good. In fact usually when I google my questions, the first few hits are always SO posts. If it's a question about the Rhino SDK or Grasshopper, you can ask it either on the GH forums (where we are now), or on Discourse. We're not as quick on the draw as SO, but we do know about Rhino. If you're looking for a basic explanation of what a keyword or a type is for, perhaps with an example, MSDN is the best first choice. In fact if you google the name a of a .NET type, the first hit is almost always an MSDN page.…; Added by David Rutten at 2:03pm on December 3, 2014
