PlyEdit: G - Mark

Marking lets you select faces in various ways for later hiding, smoothing or removal. There are several marking operations, all accessed via the <G> key. Marked faces are drawn green, that's why the <G> key is used.

Figure 1. Marking Menu

Figure 1 shows you what you get once you have hit the <G> key; a handy reference to the various operations towards the bottom of the window.

<LMB> - Marking Inside Box

You can draw out a box by holding down the <LMB> while dragging the mouse; let go of the mouse button and all faces inside the drawn box will be marked (see Figure 2). This includes faces that might be on the other side of the object, obscured behind the faces at the front. Hidden faces will not be marked.

Figure 2. Marking Inside a Box

<RMB> - Unmarking Inside Box

Draw out a box using the <RMB> and all faces inside the box will be unmarked (see Figure 3).

Figure 3. Unmarking Inside a Box

<G> - Painting

You can use the mouse pointer to mark faces in a more interactive way using the painting method. By typing <G> a second time you'll paint a single dot under the mouse pointer. Unlike the box selection method, only the faces you can see are marked; the painting doesn't go all the way through the object.

Figure 4. Painting

If you want to paint more than one dot, just hold down the <G> key and faces will be marked wherever you move the mouse pointer (see Figure 4). When you want to stop painting, let go of the <G> key.

If you want to unmark using the painting method, use <Shift-G> instead.

<F> - Filling

To mark an area of unmarked faces in a flood fill fashion, move the mouse pointer into some part of that area (see left side Figure 5) and type <G><F>. The flood fill will not cross a boundary of already marked or hidden faces ( see right side Figure 5).

Figure 5. Filling

In Figure 5 the smile of the face has been extended to fully encircle the ankle, before filling, otherwise the whole leg would have been marked.

You can unmark using the flood fill method by just pointing the mouse pointer at an area of marked faces before filling.

<=>/<-> - Grow and Shrink

Use <G><=> to grow or <G><-> to shrink the current marked area by one row of faces. The marking menu will remain active after the change, so you can use <=> or <-> again to further expand or shrink the marked area.

<S> - Swapping

To swap the marked and unmarked status of all visible faces, type <G><S> (see Figure 6).

Figure 6. After Swapping

<U> - Unmarking

To unmark all visible faces, type <G><U>.

<Home> - Focus

To focus the camera on all visible marked faces, type <G><Home>.
