Grasshopper

algorithmic modeling for Rhino

I thought this may be the ticket to applying texture maps to some objects in GH using

Rhino.sdk in a Legacy component. The geometry component outs okay and I dont have any errors but it doesn't succeed in applying the custom texture map. Any help would be great.

Thanks

Sam

Only 6 months late! I have figured this out in C#. If you need other languages I'm sure you can adapt it but the SDK has made this operation quite easy now

Rhino.Render.TextureMapping tex = Rhino.Render.TextureMapping.CreateBoxMapping(MyPlane, MyX, MyY, MyZ, true);


Rhino.RhinoDoc.ActiveDoc.Objects.ModifyTextureMapping(MyObjectGUID, MyMapChannel, tex);

Hi Mr VanMater.

Hope all is well, long time!

Just came across this. Do you, or anyone else know how to access the box mapping information of an object.

I got here:

https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_Render_T...https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_Render_T...

But I don't know how to use it.

I know this post is 5 years old. But hey never too late.

Hope all is good in the states

Cracked it!


Rhino.DocObjects.RhinoObject obj = doc.Objects.Find(ID);

var txt = obj.GetTextureMapping(1);

var pln = new Plane();
var d1 = new Interval();
var d2 = new Interval();
var d3 = new Interval();


bool b = txt.TryGetMappingBox(out pln, out d1, out d2, out d3);


A = new Box(pln, d1, d2, d3);

Is it possible to create this definition below for a box mapping (human plug in) without grasshopper using python or rhinoscript so that I could input and output surfaces or polysurfaces and not only meshes.
