In this paper, we propose a fragment-based evaluation method for non-uniform B-spline surfaces using recent programmable graphics hardware (GPU). A position on a non-uniform B-spline surface is evaluated by the linear combination of both control points and B-spline basis functions. Hence the computa … Continue reading “Evaluation of Non-Uniform B-spline Surfaces on GPUs”

Tectonic Structure Modeling using CHIKAKU DB/CAD
We have developed the systems of reconstructing the 3D computational models of tectonic structure called CHIKAKU DB/CAD as a part of projects for developing simulation software, for the purpose of the clarification of the mechanism of earthquakes, and the prediction of the earthquake wave propagatio … Continue reading “Tectonic Structure Modeling using CHIKAKU DB/CAD”
Surface Quality Assessment on GPUs
In this paper, we propose a method of subdivision surface quality assessment by reflection lines on programmable graphics hardware (GPU). Using reflection lines is stable for surface quality assessment because the shapes of these lines are changed according to a slight variance of surface shapes. Th … Continue reading “Surface Quality Assessment on GPUs”
MeshToSS: Converting Subdivision Surfaces from Dense Meshes
This paper introduces the theoretical aspects of MeshToSS, a software system for converting dense triangle meshes into Loop subdivision surfaces. The software takes mesh-format data such as VRML and transforms it into a subdivision surface that approximates the input mesh. The output is either the c … Continue reading “MeshToSS: Converting Subdivision Surfaces from Dense Meshes”
