If I know the [x y z] coordinates of a star in space, with earth as the origin (units in light years to be specific), how can I transform that coordinate vector into an [x y] coordinate that I can plot with the centre of the constellation at the origin. I would like to be able to input the [x y z] coordinates of the stars to a program and have a automatically generate the image of what the constellation would look like from earth.
Once I know I don’t have to physically draw the what the constellation would like from looking at others.
Any input will be accepted.
Thanks,
Justin
