View-based rendering: Visualizing real objects from scanned range and color data
Eurographics Workshop on Rendering 1997, 23-34.
Blending of textured depth meshes using soft z-buffering.
Modeling arbitrary real objects is difficult and rendering textured models typically does not result in
realistic images. We describe a new method for displaying scanned real objects, called
view-based rendering. The method takes as input a collection of colored range images covering the
object and creates a collection of partial object models. These partial models are rendered separately
using traditional graphics hardware and blended together using various weights and soft z-buffering. We
demonstrate interactive viewing of real, non-trivial objects that would be difficult to model using
Essentially, this approach performs runtime blending of precomputed textured depth meshes (TDMs) used as
impostors. It is yet another interesting point in the broad space of image-based rendering techniques.
