SC 99-33 Malte Zöckler, Detlev Stalling, Hans-Christian Hege: Fast and Intuitive Generation of Geometric Shape Transitions
Abstract: We describe a novel method for continuously transforming
two triangulated
models of arbitrary topology into each other. Equal global
topology for
both objects is assumed, extensions for genus changes
during metamorphosis
are provided. The proposed method addresses the major
challenge in 3D
metamorphosis, namely specifying the morphing process
intuitively, with
minimal user interaction and sufficient detail.
Corresponding regions
and point features are interactively identified. These
regions are
parametrized automatically and consistently, providing a
basis for smooth
interpolation. Utilizing suitable 3D interaction
techniques a simple and
intuitive control over the whole morphing process is
offered.
Keywords: morphing,
