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

grab-geometry-projection1.gif

The dialog shows/hides with the has the following tabs Press [Enter] or the ok.gif 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.gifROT-DEFI:

Rotdefi:

roto-translation (normal or inverse) Selecting a LATTICE.gifLATTICE region the Rotdefi is automatically selected

[Bookmarks] save/recall geometry views:
Plot:

all saved views are stored as Geometry plots in flair

add.gif:

add a new bookmark

del.gif:

delete currently selected one

save.gif:

save the present location to the selected bookmark

ok.gif:

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
