I get “TypeError: a is undefined” when I try to load specific VTK file

问题

I try to load VTK file using three.js, I have changed only one line in example file:

loader.load( "models/vtk/srtm.vtk" );

Here is my VTK file. There is TIN vector map, prepared in GRASS GIS, and converted using v.out.vtk command.

I am very new in Three.js and 3D Graphics, I just want to check some possibilities of Three.js for further work.
