axis.obj has X axis/bar on negative X axis?

[davidsummers]

Thanks a lot for your videos.

I'm using them to experiment with some things in 3D.

One question I have is whether the axis.obj is the correct orientation?

It appears to me like the X bar and X symbol are on the negative X axis rather than the positive X axis.

Is this correct? If so, why was it done this way?

I would think that each axis bar and symbol should be on the positive axis for that direction.

If not, what am I missing?

If so, could it be re-drawn/modeled with the X axis on the positive X axis?

The main reason I mention it is because it caused me a lot of confusion when I was trying to debug my 3D routines, the numbers kept coming out opposite or negative to what I thought they should, until I realized that the model was drawn that way.

I don't know any way to fix it other than to re-do the model.

Maybe I'll try importing it into Blender and re-working it.

Thanks!

I created PR #40 to fix the problem.

I loaded the original axis.obj into Blender3D and flipped the X axis and saved it and tested.

This fixed the problem in my experiments.
