Description: In this paper, we propose a practical method for hardware-
accelerated rendering of the depth image-based representation (DIBR) object,
which is defined in MPEG-4 Animation Framework eXtension (AFX). The
proposed method overcomes the drawbacks of the conventional rendering, i.e. it
is slow since it is hardly assisted by graphics hardware and surface lighting is
static. Utilizing the new features of modern graphic processing unit (GPU) and
programmable shader support, we develop an efficient hardware-accelerated
rendering algorithm of depth image-based 3D object. Surface rendering in re-
sponse of varying illumination is performed inside the vertex shader while
adaptive point splatting is performed inside the fragment shader. Experimental
results show that the rendering speed increases considerably compared with the
software-based rendering and the conventional OpenGL-based rendering
method.
