We simulate 3D models of EUV images of flare and CME events,
using TRACE EUV movies. TRACE movies show 2D images in projection
along a particular line-of-sight. We simulate 3D models of erupting
filaments, flare loops, and postflare loops using: (1) a ``finger
printing'' technique to trace linear structures in 2D images;
(2) geometric 3D models based on force-free fields and
curvature radius maximization of flare loop and flux rope structures;
(3) conservation of velocity and acceleration parameters;
(4) multi-temperature plasma filling according to hydrodyamic scaling laws;
and (5) 2D projections from secondary line-of-sights that correspond
to viewpoints of the secondary STEREO spacecraft. From such
simulations we envision to illustrat 3D time-dependent models,
what would be observed at the two STEREO spacecraft positions
as well as from a near-Earth spacecraft such as SoHO. These simulations
are used to test STEREO analysis software and to investigate what physical
parameters and geometric 3D reconstructions can be retrieved from
STEREO/SECCHI data.
