Incorrect overlay of vti and stl from the same dicom series

Thank you for your comment.

The coordinate system of vtk.js seems to be LPS.

I am currently following your advice.

The STL was exported based on the LPS system. The exported stl seems binary, is there an option to choose ascii?

Because my code does not seem to read the binary right now. So I have to select the ascii through the blender and save the stl file to render it.

As a result, the same result was obtained. Is it a problem to re-export stl files in ascii format via blender?

Thank you!!
