Fig 2. Mesh Colors

Import 

Load in another PLY file as a separate mesh. Fig 2 shows the different coloring applied when multiple meshes are loaded. As you can see, its possible to have many meshes loaded, but only the 2nd "red" mesh can be moved around or sculpted. To avoid confusion, its recommended that you only work with 2 meshes at a time, that is, the 1st "white" mesh and the 2nd "red" mesh.

Fig 3. Postioning Meshes

Fig 3 shows the mouse controls you use to move the 2nd "red" mesh about. You don't need to aim the mouse pointer at the mesh, just have it anywhere inside the graphics window to perform the action.

Replace 

If two meshes are loaded, a file selection window pops up, and the PLY selected will replace the 2nd mesh. If three meshes are loaded, the 2nd is deleted and the 3rd is moved into that position. This tool is normally used to substitute a hirez mesh for a decimated copy that has already been positioned in the scene.

Cut 

Removes <G> marked faces from the 1st mesh and puts them into a new mesh at the end of the list.

Copy 

Copies <G> marked faces into a new mesh.

Roll 

Changes the mesh ordering by one step. If there's only 2 meshes, this swaps the 1st and 2nd meshes around.

Paste 

Copies the faces in the 2nd mesh into the 1st mesh, then deletes the 2nd mesh.

Blend 

Smoothly blends in faces from all the other meshes, then deletes those meshes. You will be prompted for a brush size in the 3D window; if the overlapping faces aren't intermixed that well, then you may want to increase the default brush size to make sure that faces further apart are still blended together. If the brush size is too small then you will end up with a double skin in the overlapping areas.

Delete 

Delete all other meshes, leaving just the 1st mesh.

Space Mode 

Normally the 2nd "red" mesh is rotated by holding <Space> then click'n'dragging the <LMB>, and moved with <Space-MMB>. For safety reasons, you can only scale the 2nd mesh by first selecting Scale next to the Space option, then use <Space-RMB> to resize.

Mirror 

Mirrors the last mesh in the list about the Y-Z plane (i.e. its X coordinates are reversed).

Refine 

When you are happy with the initial position, select the Refine button. In the CyEat Display window you will see a whole bunch of wobbling error vectors. These illustrate the differences between the two meshes, and throughout the refinement process they should get shorter and shorter.
