[vtkusers] Fixed point recast mapper problem

[Vidyadhar]

Dear VTK users
I found out the problem. My entire volume is smaller the ONE unit. I had set sampling distance to smallest dimension of the voxel. During interaction it was getting changed to default value of ONE and hence the volume was disappearing. Now I am adjusting the interactive sample distance also and now during interaction the volume does not disappear.

Dear VTK users
I was using ray cast mapper (unsigned char/short) as it was in VTK 4.2. During interaction, this used to blur but show some approximation of volume.
Now I am trying to use fixed point ray cast mapper in VTK 5.0. During interaction, this one is completely blanking the volume. Interaction is not slow. Only when interaction ends, the ray cast volume gets rendered. Is this behavior intentional? If not, what could be problem?. What can I try or check?
