With 3D-Equalizer's new camera parameters (Lens Center Offset x/y, Anamorphic Squeeze, Curvature x/y and Quartic Distortion) any imaginable type of lens distortion can be compensated. These parameters can be entered in the respective fields of the Camera Adjustment Window - or the new LDE (Lens Distortion Editor) of the Zoom Window can be used. By modifying each lens distortion parameter with the mouse, the user can precisely control the shape of a virtual distortion grid until it lines up with a "grid shot" or with the straight edge of a real world object from the original footage. Lining up rendered image material precisely against distorted live action footage can be a hard job, since most of today's animation packages do not support lens distortion rendering. The solution to this problem is "WarpDistort" 3D-Equalizer's new image processing tool, which applies lens distortion to rendered images or removes lens distortion from live action footage. 3D-Equalizer V3 includes an extensive toolkit for analysing the quality of reconstruction. Graphical quality curves show the deviation of the entire result or only a single point. The reconstructed 3D tracking points can be directly compared with the original motion tracking using a back-projection in 2D, while the z-depth reconstruction quality is represented by 3D error ellipsoids. All in all, these tools make it very easy to identify, diagnose and immediately fix just about any tracking problem TCL is a powerful scripting language that has been developed over the last 10 years by the open source community. 3D-Equalizer supports TCL and provides more than a hundred additional commands that let you access its project database. Every 3D-Equalizer object-type can be created, deleted or modified. You can write TCL scripts that import/export any type of data or that perform a specific task within 3D-Equalizer, like a classic plugin. Even complete exportfilters can be implemented. TCL is the secret weapon that integrates 3D-Equalizer into any imaginable production pipeline!
