set spherical mapping programmatically

Hi,

Does anyone know how to set spherical mapping in rhinocommon (C#) ?

We apply a material programmatically with the code below but don't succeed in getting the spherical mapping set up for the same object...

//init objects
RhinoObject obj = RhinoDoc.ActiveDoc.Objects.Find(myobject_guid);
Material mymaterial = new Material();

//set enviromment texture
mymaterial.SetEnvironmentTexture(examplecolor_path);
mymaterial.CommitChanges();

//set material on object
obj.Attributes.MaterialIndex = RhinoDoc.ActiveDoc.Materials.Add(mymaterial);
obj.Attributes.MaterialSource = Rhino.DocObjects.ObjectMaterialSource.MaterialFromObject;
obj.CommitChanges();

//init spherical mapping
Rhino.Render.TextureMapping map = Rhino.Render.TextureMapping.CreateSphereMapping(new Rhino.Geometry.Sphere(new Point3d(0, 0, 0), 1));

//set spherical mapping
?????????

many thx,

Elco & Jan

Hi Elco & Jan,

The TextureMapping has to be set directly on the RenderMeshes of an object. You can do so with the TextureCoordinates property of any Mesh.

As far as i know it's not possible yet to set a custom RenderMesh to a RhinoObject. But you can do texture mapping for display purposes of your own geometry objects.

Here is an example in GH C#:

Cheers,
