Scalar fields\Arithmetic

Menu / Icon

This tool is accessible via the 'Edit > Scalar fields > Arithmetic' menu or the icon in the upper main toolbar.

Description

This tool allows to:

• perform standard arithmetic operations between two scalar fields of the same cloud (+,-,*,/)
• or apply mathematical functions to a single scalar field

Edit > Scalar Fields > Arithmetic dialog

Other than the standard operations (that can be applied to a second scalar field or a constant value), the other supported mathematical functions are:

• square root
• power of 2
• power of 3
• EXP (exponential)
• LOG (natural log)
• LOG10 (base 10 log)
• COS (radians)
• SIN (radians)
• TAN(radians)
• ACOS
• ASIN
• ATAN
• Integer part
• Inverse (1/x)

Since version 2.6.3:

• the user can select a constant value instead of a secondary scalar field for the standard operations (+,-,*,/)
• the user can choose to update the first scalar field directly ('in place'). Otherwise a new scalar field will be created. Anyway the source scalar fields are never deleted.
