Colormaps enable the representation of data attributes with gradient-based color schemes. These can currently be applied to:

• Borehole Data → Drillhole Colormap
• Volumetric Data (Voxel Grids) → Volume Colormap

Key Colormap Features:

• Pre-Defined Colormaps: Choose from a variety of built-in colormaps. The default is the opaque Viridis colormap.
• Grouped by Type: Colormaps are categorized as opaque, transparent, or solid colors.
• Colormap Min Max: Adjust the value range the colormap spans. Use Rollback to restore the minimum and maximum values from the volume data.
• Pop-Out Colorbars:
  • Colorbars can be popped out into the main view for constant visibility.
  • The outer window hides when not hovered over.
  • Multiple colorbars can be popped out simultaneously.
  • Colorbar Label: Add a custom label to pop-out colorbars for better dataset identification.

Volume-Specific Feature

• Alpha Multiplication: Adjusts the transparency of applied colors in Direct Volume Rendering, making it possible to see deeper into the volume. The control is visible in other render modes but affects Direct Volume Rendering only.

For volumes, transparent colormaps can be applied. In this example, the colormap is also displayed as a pop-out panel.
