This is the same as the implicit ``` ``` conversion used when setting the node's data type to *Float*. ``` ``` :Dot Product: ``` ``` Compare the dot product of the two vectors with the separate *C* input, using the selected operation. ``` ``` The dot product outputs a single value that says how much the two vectors "agree". ``` ``` :Direction: ``` ``` Compare the angle between the two vectors with the separate *Angle* input, using the selected operation. ``` ``` The vectors are normalized, so their length does not matter. ``` ``` ``` ```Operation ``` ``` :Less Than: ``` ``` True when the first input is smaller than second input. ``` ``` :Less Than or Equal: ``` ``` True when the first input is smaller than the second input or equal. ``` ``` :Greater Than: ``` ``` True when the first input is greater than the second input. ``` ``` :Greater Than or Equal: ``` ``` True when the first input is greater than the second input or equal. ``` ``` :Equal: ``` ``` True when both the difference between the two inputs is smaller than the *Epsilon* input. ``` ``` :Not Equal: ``` ``` True when both the difference between the two inputs is larger than the *Epsilon* input. ``` ``` :Brighter: ``` ``` True when the first color input is brighter than the second. ``` ``` :Darker: ``` ``` True when the first color input is darker than the second. ``` ``` ``` ``` ``` ```Output ``` ```====== ``` ``` ``` ```Result ``` ``` Standard Boolean output. ``` ``` ``` ``` ``` ```Examples ``` ```======== ``` ``` ``` ```.. figure:: /images/modeling_geometry-nodes_utilities_compare_direction.png ``` ``` :align: center ``` ``` ``` ```Here, the compare node is used with the *Direction* mode to compare the direction of the ``` ```sphere's :doc:`face normals ` to the "direction" ``` ```of the cube object's location. Anywhere that the directions are less than 32.9 degrees apart, ``` ```the faces will be selected, and deleted. ```
