Hello, I'd like to add coordinate labels (-2,1,0,1,2,... onto the ticks in the graph) to a specific axis in my graph in my program - z-axis.
There's a method add_coordinate_labels() in the repository, which unfortunately only seems to work for the x and y-axes.
Does anybody know how can I make it/something else work for the z-axis, or even more in general, for an arbitrary axis in any 3D graph?
Thank you for all the possible answers.
So I was printing and in the middle of the print, the filament got stuck ( my fault- dont ask๐) but the printer kept printing without filament. When I noticed, there was an inch above the printed material of just nothing. So I paused the print in Octoprint. I took a picture of the current position on the Ender's screen. But then I accidentally reset the machine. The nozzle is still in its paused position which is also the position I have a picture of. But because of the reset Ender doesn't know any of its position and flashes ??? . So how do I send the printer the coordinates that's it's at right now? What command? My thoughts was to tell it what position it's currently at. Then command it to move the nozzle to the last layer and place it at a corner. Get the layer and coordinates info from the screen and then edit the Gcode so it can start up again at that spot and finish the print.
I'm new to this so am I thinking this through correctly or is there an easier way?
Thanks for your help! Chad
Hello, im fairly new to mapping and I always find myself with the Problem of rotated Boxes, Floors aรณr walls, that i cant fit together perfectly. they are always either overlapping or they have a tiny gap in between. Furthermore I dont really know how to get a 90 degree angle, if e.g. 2 walls are not in line with the coordinate axis. Is there a way to get a "local" coordinate system or something like that? Can you build the whole room aligned and then just rotate the group?
Thanks already for helping!
I am attempting to write my own cad/cam software...
I already know about left-hand and right-hand coordinates (I'm using right), and I already know about axis rotation (clockwise when viewing the axis from the origin point). What I am wondering is if there is a common "zero-degree-rotation" point defined for the three axis. It would be useful to have an absolute rotation reference.
For the x and y axis I would suppose you could say that they are both aligned horizontally, so their zero-degree-rotation points could be the plane of the other axis of that pair--so that "zero degrees rotation" would mean basically "flat". That's my assumption though, I haven't seen this mentioned anywhere yet.
And then where would the z-axis zero-rotation point go?
When i solved it i got x=-5, x=-1, but the answer says, no x-coordinate.. some help would be appreciated.
I work with a lot of C3v-symmetric coordination complexes in my research and for years now, to draw out descent-in-symmetry d-orbital splitting diagrams I start from an ML4 tetrahedron, but with one of the M-L bonds collinear with the z axis, such that the 3-over-2 splitting diagram has z^2 , xz, yz in the "t2" set and x^2 -y^2 , xy in the "e" set. I put the t2 and e irreducible representations in quotes as the actual Td point group lists xz, yz, xy under t2 and z^2 , x^2 -y^2 under e. This is because the coordinate axis for Td is arbitrarily chosen to bisect the two L-M-L angles, rather than be collinear with z in my desired orientation. Effectively what I'm doing is relabeling the d orbitals in the C3v subgroup of Td, such that the "t2" set, under C3v IRRs, has an a1 (z^2 ) degenerate with an e set (xz, yz), with another e set (xy, x^2 -y^2 ) lower in energy.
So my question is, what's the mathematically rigorous way of performing these axis reorientation transformations? My method of doing it is super qualitative (basically you recognize that with an M-L bond aligned with z there are no ligands in the xy plane, so xy and x^2 -y^2 must be degenerate and nonbonding, and the rest of the orbitals must be in the "t2" set) but I figure there's probably a way to do this with any arbitrary point group and axis orientation. I've just never learned it in any of my inorganic or p-chem classes.
I'm confused about this because I've seen both being used in reaction coordinate diagrams (attaching two pictures here). Are they used interchangeably in most cases? I know the concepts are not the same, so I'm confused on how to discern whether we are looking at the change in enthalpy or Gibbs free energy in a particular situation when the y-axis is simply labeled "energy."

On the wikipedia page for spherical coordinates, it shows how to convert from spherical to Cartesian and vice versa, but when converting from spherical to cartesian it assumes the 'Up' direction is 0, 0, 1 (X, Y, Z).

How would I convert spherical coordinates to cartesian given an inclination angle, azimuth angle and a axis normal vector?
Here is the F(x):
I assume that for this type of question you have to differentiate it right of the bat, but I have no idea what to do aside from that.
Thanks for any help!
I know the easy answer for most objects is to simply rotate the object's pivot so Y is up when you export it, but changing pivots for something like bone systems doesn't really work and when you get something into Unity that has Y-axis as up but the bones use Z, animations work properly but the bones themselves are like 90 degrees to the model, which is awkward to look at (though it does work). Is there any setting for Max that lets you just uniformly have Y be up?
