hi
just trying to help. assuming the camera distance/focal length is 2
one unit would give 0.667 which is close to what you observe
two units would give 0.5 not 0.25 is that what you see?
If not sorry to waste your time.
regards
Mark

maybe the difference is that you need to take into account that the
default camera is some distance away already and its not set to 1. If the
default distance was 2 units then another z unit would need 0.667 shrink to
simulate.

....and maybe* not.* You may wish to consider testing what you are relating
about unit size. Moving something back 2 units in z ends up with something
that isn't 1/4 size of something that is at z=0. Your statements are
invalid.

Last night, I pushed a sprite back in z one unit and a sprite that wasn't
pushed back was something like. 637 to be the same size when at z equals
0.

hi
isnt it just 1/n?
1 unit away same size
2 units away 1/2 size
3 units away 1/3 size
4 units away 1/4 size etc

Quoting George Toledo <[email protected]>:
What kind of equation would be needed to utilize Z coordinates in QC in
a
way that doesn't change Z translation, but could be used to reduce X/Y
scale
in a way that makes the object appear to be equivalent size that they
would
be if translated in Z? In addition, is it possible to emulate the
apparent
reduction/exaggeration of horizontal or vertical movement of a sprite as
it
is moved in z by performing math on x/y translations on an object where z
isn't at 0?
Forgetting the x/y translate, it would be nice to know the equation to
make
a sprite the same size it is at z=-1, z=-2, z=-3 and so on, by
manipulating
x/y scale for instances when one wants everything to work in only 2
dimensions. The relation isn't linear, and I'm not sure how to back into
it.
If this has been covered, forgive me.
