See for example <a href="https://uk.mathworks.com/matlabcentral/fileexchange/27390-mesh-voxelisation">here</a> (note, I have never used this function).</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/how-to-import-a-geometry-stl-file-to-use-as-a-propagation-medium#post-7170 Thu, 16 Jan 2020 07:42:18 +0000 mohi 7170@http://www.k-wave.org/forum/ <p>hi fahim<br /> i am interested in your problem.and have same problem.<br /> can you give your mail for more speak about it?<br /> thanks<br /> <a href="mailto:mohi1a2@yahoo.com">mohi1a2@yahoo.com</a> </p> http://www.k-wave.org/forum/topic/how-to-import-a-geometry-stl-file-to-use-as-a-propagation-medium#post-7169 Wed, 15 Jan 2020 18:21:51 +0000 MFMIAH 7169@http://www.k-wave.org/forum/ <p>Hi,</p> <p>I am trying to import a specific geometry into my kgrid to use as a propagation medium. I will then want to assign the parameters such as sound_speed, density, alpha_power, alpha_coeff, and BonA to the geometry.</p> <p>How would I be able to do this?</p> <p>I have seen in previous posts that the function hounsfield2density can be used. However I don't think this will work for me as I am not using a CT scan (DICOM file), I am trying to import an stl file.</p> <p>Thanks,<br /> Fahim </p>
