AB: 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.
