hi, i am using im4.0 , i am practicing the reconstrunction of human face following your example--alex. but there is a big problem that at the 2 step in your general workflow. that is: how to put the modelling locators on the face? i have to put about 200 modelling locators one by one on the face by my own hand ? is there any efficent way to do this? and is there any more detailed tutorial for this face reconstruction?
thanks

hi,
not pathetic at all, we provide an example with ImageModeler 4, you can download it at:
ftp://ftp.realviz.com/private/support/Alex.zip
I am not sure that you will be able to load it in IM3.5 but at least you will see the two sets of images.
the first set with lines in the face are for calibration and modelisation, then you export the model or simply save the project in .rzi format.
The second set of images without lines drawn in the face are for texturing.
You calibrate these images, you load the model you saved in the first project, and you texture the imported model with the nice images.
Here is the workflow:
First when taking your shots, it is advised to take two types/sets of pictures:
- one set for the textures (+ 3 crosses drawn on the face).
- another set with a grid on the face to help modelisation (+ same 3 crosses)
General workflow:
-----------------
0- start a project with the grided face pictures (00_face_grid.rzi)
1- calibrate this scene (01_face_grid_calibrated.rzi)
2- put modelling locators on the face with the help of the grid (02_face_grid_modelling.rzi)
3- create a mesh from the modelling locators (03_face_grid_mesh.rzi)
then export it as an obj file (face_mesh.obj)
4- start a new project with clean face picture and calibrate it (04_face_clean_calibrated.rzi)
5- now import the mesh into this scene and pin it on the face (05_face_clean_mesh_import.rzi)
6- extract the textures (06_face_clean_mesh_textured.rzi)
7- retouch the textures within a 2D software to clean the last marks (07_face_clean_retouched.rzi)
Note: in the clean pictures, the little markers on the face are there to help pinning the mesh on the clean face.
