Master
the Art and Science of
ι
Written by the
matchmove
supervisor at a leading effects studio, this book is much more than a technical primer. It helps
you think like a pro so that you can find the right solution for your
matchmoves,
no matter how tricky. You ll also find
coverage of tasks that commonly go hand-in-hand with matchmoving, along with advice on the contributions you can
make on the set of a live-action shoot. Whether you re a student or professional, Matchmoving: The Invisible Art of
Camera Tracking gives you the knowledge and perspective you need to quickly and successfully solve every
matchmove.
I Find out mitiere proxy geometry will help the most.
Coverage includes:
How
matchmove
programs work
Perspective matching
Getting optimal 2D tracking data
Calibrating/solving cameras
Using automatic tracking
Fitting
matchmoves
into a CG set
Mastering matchamation techniques
Modeling from
matchmoves
Troubleshooting bad
matchmoves
Multi-purposing
matchmove
data
Animate your
matchmove
cameras.
Featured on the CD
On the enclosed CD, you ll find tutorials, a
collection of support files to help with various
matchmove
tasks (sample camera reports, set
reports, distortion grid, and more), plus demo
versions of matchmoving programs.
