I have two Vectors on a sphere, and I am trying to figure out how to plot points along a curve between the two Vectors at an arbitrary distance between the two. I know the position of the start and end Vector, as well as the radius of the sphere. Can anyone help me formulate and come to an understanding of the equation I would or could use to achieve plotting these points? I looked into the great circle distance, but was unsure how to get more than just the distance from the equation, as I want to plot objects along this course. I have included an image for reference, of what I am trying to achieve. Thanks in advanced for any help and understanding that you may be able to provide!
