Data mapping GUI – basics
• Mapping type choice:
• cmap – colour map
• rgb – RGB components
• texture – texturing (only in Viewer 3D)
• Transparency:
• transp – image Alpha component
• Colour map
• mapped data component
• mapped data range
• colour map choice
• view and brightness of the colour map
• map quantization
• map reversion
