hi all does anybody know a way to change axis of the gemwin.
if i make a rotation to square, it rotate around an axis which is the middle of the gemwin
if i first make a translation to the square and after a rotation, it still rotate around the axis in the middle of the gemwin.
is it possible to move the axis of rotation in gem?
one message for 2 questions (discount message!)
when i apply a texture to a polygon (still in Gem), a strange event occurs to my texture
with the following patch, my texture "breaks" in the middle. it would be nice to texture a free form like polygon and to resize the form as i wish without such perturbation in the texture.
have nice time nicolas

if
gemhead | translate | rotate | square
does not work, try :
gemhead | rotate | translate | square
transformation order is important.

hi.
just a quick comment, as i believe, from nico's last email, that it is not clear why "this works and that does not"
if

does not work,
this is *wrong*, it works!!!
try :
gemhead | rotate | translate | square
this works "too", but both patches are _different_
transformation order is important.
this is the magic!
imagine following:
- you are standing at the "origin"; you turn 90° to the right; you walk
5 steps forward 2) you are standing at the "origin"; you walk 5 steps forward; you turn 90° to the right
now think: is the result of 1) and 2) the same ? (this is: after the 2 "transformations", are you standing at the same spot and are you looking in the same direction ?)
this is the way, openGL works

and it works well
and what do you think about my polygon and texture question?

whenever you do a transformation (rotate, scale or translate) you are actually changing the local coordinate-system (this is exactly what i would call "move the axis of rotation", but a bit more powerful)

when i apply a texture to a polygon (still in Gem), a strange event occurs to my texture
with the following patch, my texture "breaks" in the middle. it would be nice to texture a free form like polygon and to resize the form as i wish without such perturbation in the texture.
could you make some screenshots of how it looks like and how you would like to have it ?
i am not really sure what "break" means; to me it sounds like the texture would not be continuous any more, which i cannot reproduce when trying your patch (which btw, is bug-prone due to undefined behaviour)
mfg.a.sdr IOhannes
the white line is "break"

hello,
it look like the white line is folowing the shape of the polygone. can you anable lighting to see a little bit better what is appening?

i've draw line to show the break i believe that texture is following the deformation of a square diagonal

thanks for the screenshot.
unfortunately i cannot see a white-line when i try your patch with (e.g.) anim-1.mov (i see it, of course on your image)
hmmm...
mfg.a.dsr IOhannes
the white line was on my original film...
don't you notice a strange deformation of your picture if you extend a little bit more the polygon corner Le 26 nov. 04, à 11:11, Johannes M Zmoelnig a écrit :

hello, I think it's cause by the shape of the primitive. can you try to texture a square if that help? c

yes, of course. that also why the texture is ok.
what do you expect while moving the polygon corner? in your exemple, the poly is drown with 2 triangles. so the corner of the texture is made by the shape of your primitive. juste look at the shape of your primitive and you'll undersand the "corner" in the texture. (take your primitive, remove the texture, enable lighting and make it rotate : you'll see a corner in the shape of the primitive. the texture is apply to the shape in a logical way)
if you wish smouth deformation of the shape, maybee curve3d could help.
otherwise, i don't understant what you want.
