AlDi:
Dear HiHosilver and Claude,

Thanks for the Input.

One of those DOH moments for me I guess :)

I have another question. Does anyone know how to the decipher or formulate the VOODOO coordinates to make them useful for Anim8or? I would prefer to use Voodoo.

Icarus is straight forward as the Rot_Quaterion is the Field used in Anim8or below:.....

# Camera track exported by ICARUS v2.09

The Voodoo for the same Frame is below......

# fov : Horizontal Field of View [degree] = (2*atan(0.5*Width*sx/f)*180/PI;
# (H0x, H0y, H0z) : RotationAxis0 [unit vector]
# (V0x, V0y, V0z) : RotationAxis1 [unit vector]
# -------------
# (x, y) : image coordinates [pel]
# (X, Y, Z) : 3D coordinates [mm]
# -------------
# Projection of 3D coordinates in the camera image:
# [ x' ] = [ Hx Hy Hz ] [ 1 0 0 -Cx] [ X ]
# [ y' ] = [ Vx Vy Vz ] [ 0 1 0 -Cy] [ Y ]
# [ z' ] = [ Ax Ay Az ] [ 0 0 1 -Cz] [ Z ]
# [ 1 ]
# or
# [ x' ] = [f/sx 0 ppx] [ H0x H0y H0z ] [ 1 0 0 -Cx] [ X ]
# [ y' ] = [0 f/sy ppy] [ V0x V0y V0z ] [ 0 1 0 -Cy] [ Y ]
# [ z' ] = [0 0 1 ] [ Ax Ay Az ] [ 0 0 1 -Cz] [ Z ]
# [ 1 ]
# then x = x'/z' and y = y'/z' , if the origin of the image coordinates is in the center of the image
# or x = x'/z' + 0.5*(Width-1) and y = y'/z' + 0.5*(Height-1) , if the origin of the image coordinates is in the upper left corner
# -------------

I'm like you. I want to use voodoo, not Icarus (which is supposed to leave a watermark on final video). There are a few tutorials on how to use voodoo with 3ds max, but none with blender or anim8or. A blender user told me how to import the python script into blender, but it was way out of my skill set as a beginning blender user.

Unfortunately, I don't know any programmers that could study the Ic2anim8 program and write one for anim8or. Maybe Steve could contact the folks at voodoo and see if they would include a script for us. I think voodoo is a university project in the Netherlands(?) and maybe it could be a student project?
Since voodoo will save the tracking as a text file, maybe we could find out a format to import the script.

Blender takes the data from the completed voodoo camera tracking and makes what is called a "point cloud" (from all the 'feature points') and also imports the camera data (rotation, movement, etc.). The targa frames are used as a background image. You are supposed to be able to determine your plane, etc, from the point cloud. At least, that is my understanding of it.

I found anim8or because of a tutorial at http://www.debugmode.com/tuts/wax/travelling_mattes/travelling_mattes.htm, on how to make traveling mattes with Wax 2.0. I want to become proficient with anim8or before completing the tut at that site.

CaptSparrow:
Could someone please upload the zip file containing everything, because my version has been corrupted, and the site no longer has it.

Thanks!
