A common approach uses polygonal meshes to represent curved objects inside an edge-based tracking system by a quadric surface, its projection represented by conic curves (blue line) approximates better the object outline object shape with a polygonal mesh, for instance, simplify the tracking furthermore, since the. This paper is based on the work of garland and heckbert who first presented the quadric error measure at siggraph '97 surface simplification using quadric error metrics for details of the algorithm michael garland's phd thesis is also recommended hughues hoppe's vis '99 paper, new quadric metric for simplifying.

It also contains the most extensive analysis of the algorithm's behavior quadric- based polygonal surface simplification, by michael garland, phd thesis, tech rept cmu-cs-99-105 [details] while analyzing the properties of the quadric error metric, we discovered that (under suitable assumptions) minimizing the quadric.

Abstract we present a simplification algorithm for triangular meshes, implemented on the gpu the al- gorithm performs edge collapses on manifold triangular meshes driven by a quadric error metric it uses data parallelism as provided by opencl and has no sequen- tial segments in its main iterative structure in order. After searching the internet i couldnt find any code that was free to use, not unnecessarily bloated, fast and memory efficient, even the quadric based method is of the algorithm from garland's phd thesis can be downloaded here: http:// wwwcscmuedu/afs/cs/web/people/garland/quadrics/qslimhtml.

Abstractðmany real-world polygonal surfaces contain topological singularities that represent a challenge for processes such as simplification, compression, and smoothing we present an algorithm that removes singularities from nonmanifold sets of polygons to create manifold (optionally oriented) polygonal surfaces.
