4.9. Projection
The projection frame allows the user to quickly and accurately place the location, zoom, orientation of the viewport as well to save and recall (bookmark) locations in the geometry
The dialog shows/hides with the has the following tabs
Press [Enter] or the to apply the change
- [Origin] move the center of the viewport to:
- x:
center of viewport
- y:
-//-
- z:
-//-
- [Extends] zoom viewport by setting the Du extends:
- Du:
half width of the horizontal axis
- Dv:
half height of the vertical axis (Read-only)
- [Move] move relative to current projection the center by:
- +u:
along the u (horizontal axis)
- +v:
along the v (vertical axis)
- +w:
along the w (towards the viewer axis)
- [Basis] quickly set the axis-basis of the plot:
- ux,uy,uz:
u vector components.
Note
it doesn’t have to be normalized to 1.0
- vx,vy,vz:
v vector components
- x-y:
z-x, z-y
- swap:
swap orientation u <-> v
- -u:
inverse u
- -v:
inverse v
- [Euler] define the orientation by entering the Euler rotations:
- Rx:
rotation in X axis
- Ry:
rotation in Y axis
- Rz:
rotation in Z axis
The order of rotation is Rz → Ry → Rx
- [Rotate] rotate relative to current viewport:
- Ru:
rotation along u axis
- Rv:
rotation along v axis
- Rw:
rotation along w axis The order of rotation is Rw → Rv → Ru
[Transform] transform current viewport with the following ROT-DEFI
:
- Rotdefi:
roto-translation (normal or inverse) Selecting a
LATTICE
region the Rotdefi is automatically selected
- [Bookmarks] save/recall geometry views:
- Plot:
all saved views are stored as Geometry plots in flair
:
add a new bookmark
:
delete currently selected one
:
save the present location to the selected bookmark
:
apply the bookmark
Note
the first field x, Du, ux, vx, Rx, Ru accepts either: - Numerical value - Vector with 2 or 3 values to substitute on the other fields
- e.g Entering on “X:” the value “10.0 50.0 -100.0”
Will set on X:10.0, on Y:50.0 and on Z:-100.0
It can be practical when you want to copy paste the values
