To find the 3D point on a 3D line with a given distance and a 3D point, you can use the following formula:
x = x1 + t(x2-x1)
y = y1 + t(y2-y1)
z = z1 + t(z2-z1)
where (x1, y1, z1) and (x2, y2, z2) are two points on the line, and t is a scalar value representing the distance along the line from point (x1, y1, z1).
Yes, you can use the distance along the line to find multiple 3D points. By varying the value of t in the formula mentioned in the previous answer, you can find multiple points that are a specific distance away from the given point on the 3D line.
If the given distance is negative, it means that the 3D point you are trying to find is in the opposite direction of the line from the given point. In this case, you can use the formula mentioned in the first answer but with a negative value for t.
No, it is not possible to find the 3D point on a 3D line if the given distance is greater than the length of the line. This is because the point you are trying to find would lie beyond the end points of the line and therefore cannot be reached by a distance along the line.
No, you cannot find the 3D point on a 3D line without knowing the coordinates of the line's end points. The formula mentioned in the first answer requires the coordinates of two points on the line to calculate the coordinates of the desired point. Without this information, it is not possible to find the point on the line.
