Editting mesh 1
This page explain major operation of editting mash. After that, you can check in a practice page later.At first, go to the edit mode.
Object center
Before the editting, you need to know the object center.
All created object have a purple dot in the shape. This is the object center. Object center is used as a reference for various operation. For example, the tracking camera target is referenced by this center.
But if you move its mesh in the edit mode, as you can see in below, the object center will be out of the mesh. To return the object center is to press "Cursor New" button in the object mode. To return the object center into the object mesh is to press the "Tab key" to go to the object mode. And while you are selecting the object, press "Cursor New" button in the button window. Or move the 3D cursole into the object and press "Center Cursor" button. This have the object center move to the object center. "Center" button moves the object to the object center.
Selecting Vertex
You can select vertex by clicking right mouse button. If you want to select several vertecies, click right mouse button with "Shift key". pressing "B key" one time, you can select all vertecies inside of box area which you draw it by mouse.
If the object has a depth(thickness), you can select selection mode for the depth by turning on the button on the header menu.
The left image shows "On". The right image shows "Off".
If drawing mode is "Wireframe" or "Bounding Box", the button doesn't appear. (Drawing mode is explained later. - drawing mode)
If you press the "B key" twice, the cursole will be changed to circle. Vertecies inside of the circle can be selected by clicking left mouse button. If you click middle mouse button, the selection is cancelled. The diameter of the circle can be adjusted by "+ key" and "- key" in the keypad, or can be adjusted by mouse wheel. To disable this mode is to press "ESC Key" or click the right mouse button.
One pressing the "A key" is to select all the vertecies. And pressing the "A key" again is to deselect all vertecies.
Pressing "L key" is to select vertex near the cursole and select linked vertecies to the first vertex. If you press "Shift + L key", this is cancel the "L key" selevtion. For example, two cubes are not connected. If you select right side cube by the "L key", only right side cube will be selected.
If two cubes are connected as below, two cubes will be selected by the "L key".
There are some way to select several vertecies at once. First, select edge pressing the "Alt key". Then, you can select all edges which connect each other in a loop. If you are pressing "Shift key" during this operation, you can select several loops.
Slect edge pressing "Alt{Ctrl key", you can select all edge which connect each other and positioned in parallel to the selected edge.
Pressing "Alt{Ctrl{Shift{M key" selects all cut edge.
If mesh consists complicate, these selection can't work due to lacking clear loop. (Following image is a result of selecting "Alt key" selection. Slection worked in partially).
In this case, "Select Vertex Path" may be help. For example, if you want to select from upper lip to lower lip, select star vertex and end vertex.
Next, press "W key" in the 3D window and select "Select Vertex Path" from appeared menu. And then, following menu shows up. You select either one to meet your operation. The "Edge Length" is to select shortest path physically. The "Topological" is to select shortest path topologically.
This is result of the "Edge Length".
Transfer
"G key" is to transfer created mesh or vertex. Press the G key and transfer object / vertex by moving mouse. And to determine is left mouse button.
This trasnfer operation is same in the object mode.
Rotation
"R key" is to rotate. Rotation follows mouse moving. And left mouse button is to determine. This is same in object mode.
Resize
"S key" is to resize. Resizeing follows mouse moving. And left mouse button is to determine. This is same in the object mode.
