3D Video Projection mapping of architectural silhouette in Special effect

3D Video Projection Mapping

. is an astonishing projection technology that allows to create dynamic displays out of any surfaces. High Tech software is used to distort any projected image in order to fit perfectly the uneven shaped screens.This relatively new technique made people around the world incredibly creative and they started to illuminate buildings, architectural elements, 3d elements, statues or sometimes amazing projects used in advertising as those for the Pepsi Can or for running shoes.

Video mapping first gained notoriety through guerilla advertising campaigns and video jockeys for electronic musicians.These advertising campaigns commonly used mapping techniques to project interactive scenes onto the sides of buildings. Common techniques for these performances included both 3-D mapping techniques and 3D projection to create the illusion of depth. In the electronic dance music community, it is becoming increasingly common for VJs to accompany the music with synced visuals. Though normal projection screens are commonly used, some visual artists are beginning to create custom made, 3D installations to project onto.

After the object is chosen or created, a virtual replica of the entire physical set up needs to be created. A virtual model of the projection surface is created, and placed within a virtual environment. Coordinates need to be defined for where the object is placed in relation to the projector. Finally, the xyz orientation, position and lens specification of the projector are adding to the virtual scene.Adjustments are commonly needed by manually tweaking either the physical or virtual scene for best results.
