<body class='hmmessage'><div style="text-align: left;"><br> Hi vtk-users, I am with a problem. I am reading xy point into a vtkStructuredPoints and I would like to save like a image, but I cant... my vtkRenderWindow shows ok, but my image dont have colors and I know why, I need to set the scalars range into the vtkStructuredPoints but I dont know what method to use, that a part of my code:<br><br>vtkStructuredPoints points = new vtkStructuredPoints();<br> points.SetDimensions( 128, 73, 1);<br> points.SetOrigin( 0.0, 0.0, 0.0 );<br> points.SetSpacing( 1.0, 1.0, 1.0 );<br> points.SetScalarTypeToUnsignedChar();<br> points.SetNumberOfScalarComponents(id);<br> points.GetPointData().SetScalars( scalars ); // <--- Doesn´t work :/ with that my image only be red <br><br>the scalars vector are double in Scientific notation I dont know if its bad.<br><br>I have been trying all possible methods but I hadn´t success.<br><br>my mapper renders ok:<br><br>vtkDataSetMapper conjunto = new vtkDataSetMapper();<br> conjunto.SetInput(points);<br> conjunto.SetScalarRange(points.GetScalarRange()); <---- But it works here<br><br>I´m thinking that a need a method like SetScalarRange from my mapper to use before in my vtkStructuredPoints.<br><br>besides, I am using vtkImageMapToColors to convert my structured points into a image. I also can post my entire code, but I made the same like this link, without the beginning because I generated my points :) http://public.kitware.com/pipermail/vtkusers/2005-December/083147.html<br><br><br>Well, someone suggest me a method for my vtkStructuredPoints? thanks in advanced.<br><br><br></div><br /><hr />Receba GRÁTIS as mensagens do Messenger no seu celular quando você estiver offline.
