[Ves] [vtkusers] Compiling VTK for iOS????

[Joachim Pouderoux]

Hi Abhishek,

VTK as is will not compile on iOS because a lot of VTK code is based on the
OpenGL rendering API which is not available on handhelds.
VES provides a modified version of VTK where all the rendering modules are
disabled. VES provides a rendering engine (based on OpenGL ES)
which is totally different as the one implied in VTK for desktop.
For now only geometric models are supported, and no volume rendering is
available for use with OpenGL ES
with VES (however I guess the CPU fixed raycasting engine -
vtkFixedPointVolumeRayCastMapper - could work as is but you may expect
slow rendering times...) Also think that OpenGL ES has many limitations,
GPU volume rendering is computation intensive and handheld GPU
are far having the same performances than desktop one.
If you need to visualize large volume models, you may consider to use a
remote rendering scheme as the one provided by ParaViewWeb.
