The geometric representation of the combined data value for a given location is larger if the Scale by Value option is not set reflecting the area of the grid for which it represents data The combined value and direction are calculated using the mean values of the combined values Increasing the LOD distance gives greater visual detail in the scene but may result in slower 3D rendering performance and a poorer visual overview of the dataset decreasing the usability of the software Scale by Value By default the geometric representation of values is the same size for all value in the grid If Scale by Value is selected the size of the geometry is also affected by the value at the grid area represented The lower the value the smaller the geometry within the area of the grid it represents 4 7 2 Cautions and warnings None 4 7 3 Procedures To modify volume options 1 Select View gt Options to open the View Options dialog 2 The Volume tab is selected by default 3 Change parameters to the preferred settings 4 a Press Apply to use the new settings without closing the dialog b Press OK to use the new settings and close dialog c Press Cancel to close the dialog without saving settings 4 7 4 Probable errors and possible causes An error message is displayed if a non numeric value is entered into the LOD distance field 4 8 Slice visualisation options 4 8 1 Functional description The Slice options can
