Navigation Cube/ja

Controlul cubului de navigație sau "cubul de navigație" "este o interfață grafică pentru a reorienta vizualizarea 3D. Implicit, este vizibil și se află în colțul din dreapta sus al afișajului 3D. Dacă vă uitați la vizualizarea 3D standard, aceasta arată după cum urmează:



Cubul de navigarea este compus din următoarele piese:
 * Directional Arrows
 * Main Navigation Cube
 * Mini-cube Menu

Planarea/plasarea cursorului indicatorul mouse-ului peste o caracteristică a cubului de navigație transformă funcția în albastru; clic va reorienta vizualizarea 3D așa cum este indicat de către funcție. (Notă: De la această scriere, pointerul nu se înregistrează perfect cu unele caracteristici ale cubului de navigație. Dacă o funcție pe care încercați să o selectați nu devine albastru, mișcați mouse-ul până când găsiți un loc care face ca funcție să devină albastră.) În exemplul de mai jos, vizualizarea 3D a fost rotită printr- un mouse gest într-o orientare "non-standard". Indicatorul este peste un colț (indicat de culoarea albastră); clic va reorienta vizualizarea 3D la o vizualizare axonometrică standard cu colțul care vă privește.



Directional Arrows
There are six directional arrows: four triangular arrowheads, one at the top, bottom, left and right; and two curved arrows, one on either side of the top arrow.

Clicking the triangular arrows will rotate the 3D view 45 degrees around a line perpendicular to the direction of the arrow. Clicking the curved arrows will rotate the 3D view around a line pointing towards you.

Main Navigation Cube
The main navigation cube ("nav cube" in the rest of this section), tracks the orientation of the actual object in the main part of the 3D view. Any operation which reorients the main 3D view will reorient the nav cube as well.

The nav cube is essentially a 3D view of a cube with its three main component types (faces, edges, and corners) enhanced so they may be easily clicked with the pointer. Clicking on a particular component will set the 3D view to have that component centered and facing you. The nav cube is somewhat "squashed", as if the feature farthest from you were larger than the feature directly facing you. This allows the features adjacent to the feature facing you to be seen and consequently selected. For example, in a "normal" view of a regular cube, when one face is facing you, you can also see the four edges of that face and the four corners of that face. In the "squashed" nav cube, you can also see features representing each of the adjacent faces, the four edges connecting the corners of the face facing you with the opposite face, and the corners of opposite face. This allows you to select any of the possible standard views except the opposite face and its edges (21 out of 26 possible views): Not possible:
 * The face facing you (does nothing, since that is the current view)
 * The four edges of the current face
 * The four corners of the current face
 * The four adjacent faces
 * The four edges leading to the opposite face
 * The four corners of the opposite face
 * The opposite face
 * The edges of the opposite face

Note: As of this writing (v 0.18), there are some problems with the nav cube; not all features are currently selectable. In particular, edges are not selectable, nor are the four corners of the immediately facing face.

Face Selection
Clicking on a face will orient the 3D view with that particular face facing you. From a face view, other selection points are available as noted above. There are four thin "bars" on each of the outside edges, representing the four adjacent faces; clicking them will select the view corresponding to the adjacent face. There are four round corners which may be used to set the corresponding axonometric view. There is also an interior set of edges and corners, which are currently non-functional.

Edge Selection
Unfortunately, edge selection is currently broken. Attempting to select an edge will select the face which lies behind it. Clicking an edge should center that edge so it is facing you.

Corner Selection
Clicking one of the corners will give you an axonometric view as seen from that corner. As noted above, currently when a face is directly facing you, the corners of that face are not selectable.

Mini-cube Menu
In the lower right corner of the navigational cube is a small cube. Clicking on this cube will bring up a menu you may use to change the type of view (Orthographic, Perspective, Isometric) and to do a "Zoom to Fit".

Moving the Navigation Cube Display
You may move the entire navigation cube control structure to another location in the 3D display by pressing the mouse anywhere in the main navigation cube and dragging. As of this writing (v 0.18), the structure will not begin to move until the mouse pointer has moved past the edge of the main navigation cube.
