Color mapping of VTK blocks
- Loads the dataset
can.ex2, applies a blue-gray background, shows it as a surface in a render view, and fits the camera. - Uses block coloring globally, then overrides one block (/IOSS/element_blocks/block_2) to be colored by the X component of the point-data array ACCL, rescales that block’s transfer function to its data range, shows its scalar bar, and applies the cool-to-warm color map.
- Orients the camera to −Y, refits, and saves a screenshot to
color-blocks-screenshot.png.
