jk/new 3daxis attempt

[jkrumbiegel]

• add 3d axis
• check axis with can_be_current_axis
• gridlines, ticks, fix inv eyepos
• axis3 as default 3d axis
• add ticks
• change to ax3 for fps as well

I'm testing this locally on my own projects now. Thanks a lot, I am really desperate of unified look between 2D and 3D ;) .

This is the test code i used:

fig, ax3, surf = surface(1:100, 1:100, randn(100, 100))
display(fig)
angles = 0:0.01:2π
for angle in angles
    ax3.azimuth = angle
    sleep(0.001)
end

Which works really well. Two comments for now.

1. perhaps it is better to auto-scale the axes, if the user does not explicitly provide bounds, so that they all have the same size, instead of data size indicating a much smaller axis. This is a problem the old 3D axis also has. For example, 2D plotting does not do this by default: if I plot 1:100 versus 0.00001:0.0001:0.0001, I don't get a super-stretched line as an AXis, but a square.
2. Attempting to change GLmakie window size after the plot leads to the error:

[jkrumbiegel]

can you try setting ax.data_aspect = :equal for the scaling thing, it should do the different scaling behavior. The symbols are super confusing right now, :same vs :equal, but I haven't come up with good ones yet and it's all preliminary anyway

[Datseris]

It works:

I would still argue that this should be the default behavior in 3D

[jkrumbiegel]

sure I was just testing the other mode last

[Datseris]

Calling xlims! etc. does not have a method yet for Axis3. I currently do manuyally ax3.limits[] = FRect3D(...) . Doing ax3.limits = Frect... directly also does not work, but works for 2D axis.

P.s.: If you don't like me reporting problems, let me know

[Datseris]

For large tick labels, they cover the axis labels:

Furthermore, the nice gray lines that connect the ticks are not shown in this example. I have not disablerd them myself, perhaps the size is a problem.
