Efficient rendering of projective model for image-based visualization

This work describes a method for synthesizing correct virtual images of a real scene, described by a set of uncalibrated reference images. The approach used is rendering a projective 3D model. Projective model reconstruction and positioning a projective virtual camera are not addressed. First, the algorithm transfers the vertices of triangles in the triangulated model and then warps interiors of triangles. Hidden faces are removed by z-buffering. The algorithm is more efficient than the ray-tracing-like algorithm for virtual view synthesis by Laveau and Faugeras (1996).
