Various applications of computer graphics, (like animation, scientific visualization, and virtual


reality) involve the manipulation of geometric models. They are generally represented by


triangular meshes due to its wide acceptance to process on rendering systems. The need of


realism and high visual fidelity and the latest advances on scanning devices has increased


complexity and size of triangular meshes. The original 3D model gets modified because of


activities like approximation, transmission, processing and storage etc. Mostly the modification


occurs due to simplification approaches which primarily use geometric distance metric as their


simplification criteria. But it is hard to measure a small distance error accurately whereas


other geometric or appearance error (like high curvature, thin region, color, texture, normals


and volumetric) has greater importance. Hence it is essential to understand the applicability of


various parameters to evaluate the quality of 3D model. This paper briefly surveys the various


errors analysis techniques, error metrics and tools to assess the quality of 3D mesh models.
