version 3.05, released in 2000
version 3.07 released last week
quite a hiatus
jepler: have you every played with VPython?
it is very cool
get the ubuntu package
the start python (interactive)
>>> from visual import *
a window pops up, with a red box in it
green ball appears
you can move the camera around and zoom, similar to the axis preview window
>>> ball.radius = 3
>>> while (ball.pos.x < 10):
... ball.pos.x = ball.pos.x+0.1
ball steadily moves along X
that seems like it could be useful in the same way gnuplot is sometimes useful
it would have made writing vismach much simpler
in my case, I've found a GPL finite element package that does text in, text out, and VPython will make it rather easy to visualize the output
I think I'll be able to have the structure bending back and forth as you watch
ramp between the undeflected and deflected node positions over time
(with the deflections multiplied by some large factor so they become visible)
wow, that sounds very cool
the FEA program is called Felt
its the only one I've found with a learning curve that I have a chance of climbing
very good manual
is it by design that no rapids show up in the axis backplot until the first feed move?
you don't say
hmmm looks like I'm still at work and at a customer
EMC: 03bigjohnt 07v2_3_branch * 10emc2/docs/src/gui/axis.lyx: add info on disappearing rapid moves in axis preview plot
cradek: why is that by design?
it would be nice to see how the tool is going to approach the work
although I guess at preview time, EMC doesn't know where the tool will be when you hit run, so it can't show the very first move
if there are two or more rapids before the first feed, it seems like it could show all but the first one

jmkasunich: that's one problem it solves - the other is I think the extents are less useful if you include these long entry moves. I made this change after working on a part the size of my thumbnail, but the preview showed mostly lines a foot long to and from the tool change locations, with the extents showing those huge numbers, and none of the actual part visible without a lot of zooming/panning.
if there is a toolchange in the middle of the program, don't you have the same problem?
those are hidden too.
how does it know to hide them?
also right after a TLO change, because otherwise you get a bogus-seeming line as the position jumps from the old to new tool point.
I bet it only hides moves to TOOL_CHANGE_POSITION, and etc
I forget the exact implementation details.
I've had the "long lines" issue - but I don't have a toolchanger, and in some cases those long moves are just to a "get the tool clear so I can measure (or unload the part)" position
nothing that would let axis know they can be hidden
you could program (AXIS,hide) etc if they are in your way
or, turn off preview of rapids
I don't tend to think of it when I'm programming
I like preview of rapids - prevents rapiding thru things
they no longer allow sellers to accept checks, money orders, etc
fuckin bastards are forcing people to use paypal

* jepler wonders if that doc change is prompted by a user report
