[solved] - Compute point at Normal

[archat]

Dear Team,

i have a cloud point in which i can see the normal lines in vizualizer. Also, i can see a call pcd.normals[0] gives a vector of 3 values. i would like to understand what this value stand for? is it a orientation value? if so how to calculate the point (C) of the straight line similar to normal drawn.

As shown in below figure, point A is my first point in PCD, and corresponding normals value is B (though it is not a x,y,z position), now i would like to compute or get a x,y,z value and its orientation corresponds to point C in the image. Request to guide me on the understanding and steps to get the point C.

Answer : A + B gave the point which is unit normal and passes through C, so depending on distance or length i required i can calculate the point C dynamically and able to draw the line.

Thanks in advance.

Got the clarity of normal values, also I am able to get the points i was expected.
