Compute

Starts a curvature calculation. Settings below can be changed before and after the calculation.
 

A new calculation will overwrite the color map values, if ''Freeze min/max values'' is off.

Visualization

Curvature type

▪Gaussian

▪Mean

▪Maximum

Choose the type of the curvature analysis to be displayed. Each curvature point has a minimum and a maximum curvature value and those can be interpreted differently:
- GAUSSIAN: The product of both curvature values is used to detect surfaces curved on both sides (extreme or saddle points).
- MEAN: Arithmetic mean of minimum and maximum curvature values. Helps to identify surfaces with abrupt curvature change.
- MAXIMUM: Displays the maximum curvature values. Helps identify problematic surfaces for milling and toolpath planning.

Use absolute value

Off: Use positive and negative values of the curvature calculation for the display of the color map. Turn off when using ''Gaussian'' type.
On: Instead use the absolute values.

Limit values to min/max

Off: Values above the maximum or below the minimum values of the defined ''Color map'' will be shown in the color defined by ''Outside min/max color''.
On: The color of the minimum or maximum value will be assigned to the values outside the color map range.

Outside min/max color

This color will be assigned to values outside the ''Color map'' range, if setting ''Limit values to min/max'' is off.

Outside min/max transparent

Off: Show values outside of the color map value range in the color defined with ''Outside min/max color''.
On: Values are hidden, if they are outside of the color map min/max values.

Freeze min/max values

Off: New calculations will overwrite the ''Color map'' values.
On: Color map values will be kept for new calculations.

Color map presets

Presets that contain predefined colors and the ''Number of values'' for the ''Color map''.
Shows ''User defined'' when no preset matches the ''Color map'' settings chosen.
 

Presets can be adjusted and added:
Installation directory\Resources\presets.xml.

Reverse colors

On: Reverses the color sequence of the ''Color map''.

Show color bands

Off: Shows a gradient transition between colors on the geometry and in the legend.
On: Shows color bands instead.

Color map

Number of values

Number of values and colors.
 

Changing the number will trigger a recalculation of the intermediary values and colors.

Reset min/max

Resets all ''Color map'' values to the min/max values of the calculation.
 

Ignores ''Freeze min/max values''.

Value automation

Update intermediate values

Interpolates the intermediate values of the color map.
 

Helpful after editing the min/max values of the color map.

Apply quantiles

Removes outlying values from the color map. The top and bottom 5 % of values are ignored to focus on the values in the middle.

Apply logarithmic scale

Uses a logarithmic scale on the color map.
 

Sometimes linear intervals obscure very small but important value ranges that are close together. This spreads those small ranges and assigns them a larger color spectrum, making them more expressive.

Miscellaneous

Apply selection to others

Color map results with different settings cannot be meaningfully displayed in the legend. This applies the settings of the selected result to all other visible results and updates the color map and legend accordingly.

Unify properties

If two or more heatmap nodes (of the same type) with different visualization properties are selected, they have to be unified before we can display the visualization settings.

Legend

Show histogram

false

On: Color legend shows a dotted line indicating the frequency distribution of the values.

Number of decimal places

4

Specifies the displayed decimal places of the color map values.

Show equidistant values

false

Off: All legend intervals are spaced according to their numeric value.
On: All legend intervals are spaced with equal distances, irrespective of their numeric values.
 

This improves visibility for very small intervals.
