3 Point Angle
Calculate the angle between 3 different points. These points are selected based on their index in the point domain, with Index B being the centre of the calculation.
In the video example, the same calculation that is occurring internally inside of the MN_topo_edge_angle node, is being handled explicity by this node. If the Index is being used as Index B then the current point that is being evaluated is the centre of the angle calculation. If this value is changed, then the point at the corresponding index is used, which results in a smaller angle in the example video.

| Angle between the points around Index B in radians | Angle |

2 Point Angle
Calculate the angle that two points make, relative to the current point being evaluated. Points are selected based on their index, with the centre of the angle calculation being the current point’s position. Equivalent to using 3-Point angle and using Index as the Index B.
In the example video, the angle calculation is similar to that of the 3-Point Angle node, but the middle point is always the current point.

Point Distance
Calculate the distance and the vector between the evaluating point and the point selected via the Index.
In the example video, each point is calculating a vector and a distance between itself and the indexed point. When the Point Mask node is used, this index is then on a per-group basis, so each point in the group points to just the group’s corresponding point.
