Back when VES started VTK rendering was based on the old fixed pipeline which does not work with OpenGL ES. To render on Android/iOS they needed to implement a rendering engine built on OpenGL ES. Due to cost and time constraints they felt they did not have time to put that codebase into VTK proper. Now we have the time and funding to work on that. It is a work in progress and still at an early stage but VTK master includes alpha support for compiling and rendering on Android and iOS. More specifically:</span></a></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoListParagraph" style><span
