Multi-view Rendering using GPU for 3-D Displays

Abstract

Creating computer graphics based content for
stereoscopic and auto-stereoscopic displays require rendering
a scene several times from slightly different viewpoints. In that
case, maintaining real-time rendering can be a difficult goal if the
geometry reaches thousands of triangles. However, similarities
exist among the vertices belonging to the different views like
the texture, some transformations or parts of the lightning. In
this paper, we present a single pass algorithm using the GPU
that speeds-up the rendering of stereoscopic and multi-view
images. The geometry is duplicated and transformed for the
new viewpoints using a shader program, which avoid redundant
operations on vertices.
