I copied the example to apply a texture to an object in c#. It works if I apply a bitmap or a trasparency but not a Emap
the code
protected override Result RunCommand(RhinoDoc doc, RunMode mode)
{
const ObjectType filter = Rhino.DocObjects.ObjectType.Surface |
Rhino.DocObjects.ObjectType.PolysrfFilter |
Rhino.DocObjects.ObjectType.Mesh;
Rhino.DocObjects.ObjRef objref;
Rhino.Commands.Result rc = Rhino.Input.RhinoGet.GetOneObject("Select object to add texture", false, filter, out objref);
if (rc != Rhino.Commands.Result.Success)
return rc;
Rhino.DocObjects.RhinoObject rhino_object = objref.Object();
if (rhino_object == null)
return Rhino.Commands.Result.Failure;
// Select texture
Rhino.UI.OpenFileDialog fd = new Rhino.UI.OpenFileDialog();
fd.Filter = "Image Files (*.bmp;*.png;*.jpg)|*.bmp;*.png;*.jpg";
if (!fd.ShowOpenDialog())
return Rhino.Commands.Result.Cancel;
// Verify texture
string bitmap_filename = fd.FileName;
if (string.IsNullOrEmpty(bitmap_filename) || !System.IO.File.Exists(bitmap_filename))
return Rhino.Commands.Result.Nothing;
// Make sure the object has it's material source set to "material_from_object"
rhino_object.Attributes.MaterialSource = Rhino.DocObjects.ObjectMaterialSource.MaterialFromObject;
// Make sure the object has a material assigned
int material_index = rhino_object.Attributes.MaterialIndex;
if (material_index < 0)
{
// Create a new material based on Rhino's default material
material_index = doc.Materials.Add();
// Assign the new material (index) to the object.
rhino_object.Attributes.MaterialIndex = material_index;
}
if (material_index >= 0)
{
Texture texture = new Texture();
texture.FileName = bitmap_filename;
texture.Enabled = true;
Rhino.DocObjects.Material mat = doc.Materials[material_index];
mat.SetTexture(texture, TextureType.Emap);
mat.CommitChanges();
//Don't forget to update the object, if necessary
rhino_object.CommitChanges();
doc.Views.Redraw();
return Rhino.Commands.Result.Success;
}
return Rhino.Commands.Result.Failure;
}
Thanks
