Scalar Data Assignment: Isocontour vs Image Scaling
In case others have the same question, I'm posting this email here:
Quote:I have some questions about the assignment. Yes, you are correct that you should first calculate the isocontours on the original, unscaled data. You can then simply scale the isocontour coordinates to the target image size, and then draw lines using those coordinates. Figure 5 is an example of this; the grey intensities in the background come from bilinear interpolation, but the isocontour overlay uses coordinates based on the original dataset (hence the straight lines - they would be smooth if you calculated the isocontours based on the scaled, interpolated data). |
