Hi Chris,

Yes, SCIRun can still do that.  If the values in the input to ShowField are Vectors, they can be directly rendered as RGB by selecting the "Conversion to RGB" option (note: this works for all Mesh types, not just ImageFields).  The components can range from -1 to 1, and the absolute value of each component is used.  For example: (0,0,0) maps to black; (0.5, 0.5, 0.5) and (-0.5, 0.5, -0.5) both map to medium gray; (1,1,0) and (1,-1,0) are both yellow.

I'm attaching an example network and a snapshot.

Cheers,
Dave

Hi everyone,

Way back in the early days of scirun I think there used to be a datatype called an Imagefield (or imageplane or something similar) which would provide a way to load and visualize 2D images with RGB values. I can't remember the exact image formats supported but it was probably some kind of bitmap format (and in any case this can be changed easily). Does anyone know if it's still possible to do this with the current version of SCIRun?  Thanks.
