不知道怎么下啊

Great plug-in, thanks for sharing it! I've just discovered a strange bug when I try to use the Custom Preview Materials component in a definition where I've clustered other components. If I try to add a bitmap to the diffuse or transparency channels, the maps fail (meaning the object previews as a solid, white material). In some cases it will accept a map smaller than 512x512 pixels. Without clustering, the component works fine with any size image. The component isn't part of the cluster or receiving data directly from the cluster. Just wanted to call it to attention. Thanks again!

Hey Andrew! Great work on this plugin. While working with the Item Selector component I noticed that the layer order doesn't match the layer structure in my Rhino file. Instead, everything is sorted in order by which they are created.. From a workflow standpoint this starts to get very confusing when my projects will regularly grow to A LOT of layers. Is it possible to have the selector match the structure from Rhino?

Hi Tim - this one-line c# script should get you a "sort index" property for all layers that you can use to sort the output of the layerTable component.

    A = RhinoDocument.Layers.Select(L => L.SortIndex);

I don't do this naturally - I use the layer index by default so that as new layers are added/rearranged, the entire order of the set doesn't change in unpredictable ways. The SortIndex changes every time you click one of the headers (Sort by color, linetype, visibility, name, etc).

Thanks for the response Andrew. So I have used the script to gather the layer indexes and sort them but I'm not sure how to apply your suggested sorting techniques. (By Material, Color, etc..) My thought or question is this: Can there be a unique identity number tagged to each layer as it is created? This way, no matter how I choose to organize my layer hierarchy in Rhino, Grasshopper can track along and not break the connection. In the example image, this simplified Rhino file is focusing on the facade development. I typically have separate top-level layers for each major component of the project similar in scale to Revit Worksets. It would be ideal to keep the flexible layer control from Rhino and have Grasshopper responding. 

- The other thought was a selective sort. So, for example, my top level layers are organized by a number (03-Facade, 04-Interiors, 05-Lobby, etc..) but then keeping the nested layers in their current organization inside.

- Final thought. Maybe I am simply overthinking this and I need to adjust my layer naming strategy from the beginning to be more methodical. What do you think?

Hi Andrew- I got it working. You can see in the image that I was able to extract the naming preface. The example added to brand new layers to my Rhino model tagged with "04-" and you can see how they are used to sort the data. I wasn't aware until now there was a separate text sorting component. The result in the 2 panels on the bottom right is a sorted list either by full name or layer name. This little move should really help stay organized moving forward. Thanks for helping to clear this up for me!

As I've been working and adding new layers with GH iterations, the layer will shuffle and get screwed up. How were you thinking to use the persistent layer ID to match? When the C# code gathers up the data, it was giving me an error because there were more IDs than layers to match.

Hi Andrew - loving these tools! I've been working on a definition to let me animate and render a point light along a curve, but have come across a roadblock: the CreateLight component doesn't allow access to all of a light's properties. Specifically, I'm looking to change the Decay option and to radically increase the light's intensity (giving CreateLight a maxed-out intensity of 1.0 in GH results in a light intensity of only 10% of what I need in Rhino).
Am I missing some way to alter these properties? I tried using LightProperties to grab the attributes of an existing reference light, but the intensity just went back to 1.0). Any thoughts?
Thanks,

Hey Andrew -

is there a way to move already existing layers with geometry in them into sublayers?  i'm working up a definition that turns off a bunch of layers when importing geometry from Revit, but i'd also like to move those layers to an 'off' layer automatically. 

Hi Dan - 

Try the attached script. It will move an existing layer to be the child of another existing layer. MakeChildLayer.gh

You are a beautiful human.

Hey all;

I have a problem, I used the "Render Tet to Screen" Component, the problem is that it goes behind the scene's objects when I'm rotating the view ... is there any way to solve the problem?

I have a excel number set that i'd like help assigning relative line thickness to at different directions. For example, at 10 north would be thicker than 5 East, 3 South, 7 West, etc. I took the spreadsheet reader to extrapolate the data, then sort and partitioned to make a relative range of data. From there, I was looking to assign line thickness and typology and a direction, but I'm a little stuck. Any help would be appreciated. 

test.gh

Hi Bomin Kim - 
without your excel document or the plug-in you used to read excel, the document you've attached doesn't help me help you very much. However, there are two basic ways to think about lineweights using Human:

1. Line thickness in Grasshopper Display. For this, use the "Custom Preview Lineweights" component, and supply the lineweights you want and the curves/lines you want to display. It has two modes - Relative (the default) where the supplied number is a pixel width, regardless of zoom, and Absolute, where the supplied number is provided in the units of your document, so that a line will always display as "20 cm" thick and scale with your zoom.

2. Line thickness in Rhino object Attributes. For this, use "Create Attributes" and supply your desired lineweight to the "plot width" input - then feed both these created attributes and your geometry to a "Bake" component. This will bake your geometry to the Rhino doc with the proper plotweight - which will show when you print, or if you enable "PrintDisplay" in the rhino command line.

Hope this helps - if not please supply a little more information so I can get closer to the problem at hand.

I am really pleased to see the new version! It is great to see you have included the Viewport properties. I have two comments:
1. The "modify viewport" is missing a camera up setting.
2. When the viewport is switched to parallel(orthographic) view, the CPlane and Camera position will drift in the background. When you then switch back to projection view, the camera will be far from the target. It also seem to drift more if the updating is more rapid. Is it a Rhino bug? I do not think it's specific to the Human plugin. Video: https://www.dropbox.com/s/buns398xf59de6u/Grasshopper_Viewport_Drif...

Is there anything to do with this?

Hi Martin - 

You're correct that Modify Viewport lacks "Camera Up." Personally I've never seen the use of this setting, but I'd be open to adding it to the viewport components if it would be of use to you.

The distance hop you notice is a Rhino thing, definitely. No idea why it does that... Strangely, if you use a different mechanism to switch between perspective and parallel, it doesn't happen. I have an alias set up to the following command: 

'_-ViewportProperties _Projection _Toggle _Enter

This will let you quickly switch between perspective and parallel without any "hopping." Hope that helps.

Hey Martin - added camera up to viewport properties and modify viewport components. See if this works for you! 

Human.gha

Hi Andrew,

That is great! Thank you very much. I have done some quick testing, seems to be working fine.

About the drifting problem, this is slightly annoying, but can try the toggle command.

Many thanks!

Hi Andrew! First of all thanks for your work, it is exactly what I needed! Great job!

My problem was to change line display thickness in rhino viewport. I enabled "PrintDisplay" and I wrote a tiny VB script component referencing the object and changing its linewidth but, of course, I got it changed directly in the Rhino model, not in an output copy from GH.

I know that it is a newbie question, but may I ask you what is your approach in this case?

Thanks!

Hi Stefano - 

Grasshopper curves do not have an intrinsic "line width" property. When I draw lines with my custom preview component, I am overriding the DrawViewportWires method and calling args.Display.DrawCurve with the optional thickness argument. 

Hopefully the above script will get you started. 

Thanks Andrew! I was following a completely wrong path.

I will practice more just to understand, but your components work like a charm!

Cheers!

Hi Andrew.

Great plugin.

I am working on an animation and using create light component, but once it gets baked the intensity of baked light in rhino does not change.

Any suggestion will be really helpful.

Thanks

Hi Jayant. What render plug-in are you using? V-ray ignores the intensity of rhino lights in favor of its own intensity value, which my components do not currently control. You should however see a difference in the Rhino Rendered viewport. 

Also, make sure your intensity is between 0.0-1.0. 

Hi Andrew.

Thanks for the reply. I am using v-ray render.

I understand now why it isn't happening. I will try to find a way around it.

Thanks.

Hi Andrew, I downloaded Rhino 6 WIP and started to play around a bit. The Human Layer Table and Object Attributes components are red.

This is the error:

1. Solution exception:This object cannot be modified because it is controlled by a document.

Hi Martin - This appears to be a bug with the new RhinoCommon shipping with Rhino 6 WIP. I am following up with the rhino developers here: https://discourse.mcneel.com/t/sdk-change-linetype-table-access/360...

In the meantime the attached update to Human should eliminate the error. Human.gha

Hi Andrew.  It seems that there is also an issue with the CreateHatch component in Rhino WIP.  There are no error messages but it is not outputting any hatch geometry.  I only tested this after loading the update that you posted for Martin.  

Is that only for Rhino WIP?  In Rhino 5 I am just inputting closed curves generated by grasshopper and then the CreateHatch component is generating hatch geometry. 

You have to add some hatches to the document first - of the particular hatch patterns you wish to use when baking. I believe this to be a RhinoCommon bug - I complained about it a long time ago on the Rhino forum. The problem is that hatch patterns do not exist in the document's "Hatch Table" until they have been added once to the document - I believe the reason for the inconsistent behavior may have to do with document templates - some may have the hatches already included while others do not. 

As a test, try creating a rectangle, hatching it with "Hatch1" or whatever, and then creating the same hatch in GH/Human. I can confirm that as long as I do this, I am able to create hatches with the Human component in the current Rhino WIP. If this doesn't solve the problem for you we'll have to look more closely. 

Andrew - I tried your suggestion and I am able to bake the hatch into the Rhino document but the hatch geometry output is still not generating any results.  I'm basically just trying to run that output into a custom preview component so that I can see the hatch pattern and assigned colors before baking them. 

I'm having an issue with accessing object attributes after using the Move component - after a set of curves is moved by a set of vectors, attaching the resulting geometry to the ObjAtts component results in an error "1. Solution exception:Object reference not set to an instance of an object." . Flattening/grafting/etc the geometry does not resolve the issue. See attached image 2016-10-24_17-21-53.png

Andrew - thank you. I should be able to figure something out now.

Hi !

I noticed that I could not retrieve the "Material name" attribute from blocks.

sorry for noob question. how do you use wildcards. i saw some Regix stuff going on but.. 

thnx

Hi, I am wondering if there is a way to generate full layer paths (create the layers+sublayers in the Rhino doc) from within the "CreateModifyLayers" function through ghypythonlib. At the moment I can only get it to generate parent layers, even using the proper syntax (parent_layer::sublayer). Using the Grasshopper component itself presents no problems, but I see no keyword argument or input that would allow me to do this in python. Thanks for any help. 

Hi Andrew,

First of all, thank-you for your incredibly useful plugin.

I have been mapping images (.tif with alpha masks) to surface geometry using your custom preview materials object (connected to DB).  In the previous Rhino WIP (June 2017, I believe), the alpha channel was working quite well.  With the new WIP (2017-07-25) the alpha channels aren't being recognized.  Do you know why this might be?

Thanks for your time.

Ah, okay.  I have separated the Tif into two Jpegs (one for the DB and one for the TB) and it is working well for what I need.  

Thank-you for the quick response!

Andrew. how can i use the mapped mesh color in order to play with the height . visually it is being presented but i cant use the values. 

thnx

Could the SaveView component also have an absolute input for pixel width and height? I understand the approach with the scaling of the current viewport but sometimes you want to have uniform aspect ratio from several files. 

Has any testing been done of Human components in Grasshopper1.0 in the Rhino6 Beta releases?

I've been working on a very large definition in Grasshopper1 which was very unstable and crashed frequently until I removed the Human: Directory Contents and Human: Item Selector components. I'm guessing there may be stability issues with either of those two components in GH1.

I also witnessed a some performance decrease in Rhino6, with files that worked fine in Rhino5 I think in my case it was due to the texture mapping components in human but I'm not entirely sure..   

Hi! Sorry for the potentially stupid post - you mention in the video included on the download page an examples file download - where can that be found? I want to use Human for continuous baking but can't quite figure it out (new to grasshopper!)

Thanks!

Hi Lucy - http://food4rhino.com/app/human is the best place to download the latest versions. And for future, since this forum is mostly dead, I've set up https://discourse.mcneel.com/c/grasshopper/human for discussion about this plug in :) 

Andrew, it's possible to retrieve a Bloc ID with Explodes blocks compoment ?
