Marc Hoppermann replied to brendon_carlin's discussion 'construct NurbsSurface from control points with weights'
Hi Florian,
The Problem lies in the way that Rhinocommon deals with control points.
In rhino control points are pre-multiplied whereas in RhinoCommon they are euclidian coordinates.
That means that you have to multiply the x,y,z coordinate with the…
Marc Hoppermann replied to Sander Boer's discussion 'Inserting a Rhino Block using grasshopper / VB'
Hoi Sander,
Currently thats not possible in grasshopper but you can use the SDK to do it.
Just copy this function in the "custom additional code" body of a vb script and call it from the main subroutine:
Function…
Marc Hoppermann replied to brendon_carlin's discussion 'construct NurbsSurface from control points with weights'
Hey Brendon,
how are you?! It's been a while!
Thought it was a nice idea so I gave it a shot.
Don't know what you were planning to do so I just created a simple example with an attractor point.
One thing: it only works if the InputSrf not…
Marc Hoppermann replied to Jachym Pesek's discussion 'input as 2d array to VB component'
Hi Joach,
If I understand your question correctly you would be better of switching to the new vb component (using Rhinocommon). These have 3 ways to access input variables (item access, list access and DataTree access). If you output data from…
Marc Hoppermann replied to Olivier Pasquet's discussion 'Visual Basic vs python'
Hey Luis,
I've seen the presentation, too and I have really enjoyed it but I am curious how long it will take them to implement it in their products... but definately worth following what they come up with...
I've uploaded his Robert…
Marc Hoppermann replied to Arthur Mani's discussion 'Network Surface'
Hey Artur,
Some time ago I put together a definition that uses the Rhino "patch" command from within a VB-component. I slightly altered it to make it work for a networkSrf.
What it does is:
- bake the inputCurves
- create a networkSrf
-…
Marc Hoppermann replied to Jesse Pietilä's discussion 'When comes the UnrollSrf ?!?!?!?!'
Hey Jesse...
did it actually work out for you with the definition I uploaded? Just curious as I have only tested it on one pretty simple case so far..

Marc Hoppermann replied to Theunis du Toit's discussion 'Create perpendicular line to 3d elipse?'
I assume that the ellipse lies on xyPLane?
Then just take the cross product of the tangent with the worldZ-Vector.
The result will be the perpendicular Vector...
Marc Hoppermann replied to Jesse Pietilä's discussion 'When comes the UnrollSrf ?!?!?!?!'
Hey Jesse,
As far as I know there is no unroll component yet.
You will have to utilize the Rhino command for it using app.runScript()
I've attached a ghx file that does just that.
As an input it takes the IDs of the surfaces. The output are the…
Marc Hoppermann replied to Lars Renklint's discussion 'Rhino patch in Grasshopper'
Hey Lars...
needed to have a patch from gh today and managed to automatically reference it back.
VB_patch.ghx
-bakes input Curves and runs the Patch command
-finds the last created object and returns it from the component.
- It also gives the…
Marc Hoppermann replied to Thomas Bildsøe's discussion 'Creating list of EH_box in Vb.net'
I get the same error...
If I use the full namespace it works fine:
Dim box_list As List(Of Grasshopper.Kernel.Types.EH_Box)
should be working without it, though. There is an import statement with that namespace...
Marc Hoppermann replied to Chris Wilkins's discussion 'Placing light objects from GH.'
now that you are placing them with code you might aswell add sime lines for the light_settings itself like:
newLight.m_diffuse = New OnColor(clr) ' just add a color input to the script
newLight.m_shadow_intensity = shadowInt ' to control…
Marc Hoppermann replied to Chris Wilkins's discussion 'Placing light objects from GH.'
Hey Atsuo,
If you replace the code by the following you will give the lights a Name that you can then find back in the scene and delete the next time the vb component get's active. This way you make sure that you don't keep pushing new…
Marc Hoppermann replied to Chris Wilkins's discussion 'Placing light objects from GH.'
sorry... forgot to attach the ghx file...
here you go

- can u please help me out with this mess thing of file?
what can i change here?
i got a bit confused because of trying a lot.
actually my aim is, at this point, doing kind of roof panels which overlap in theire 4th point the one under.
the next problem, as u can see, is the oriantaion of the panels. they need to oriente like panels on roof over another in falling direction.
so i need an input like 3 points for one panel.
thanx a lot
henri (from your last workshop at abk)
