Detailed Description

[ Geometry Shader ]. Shader to modify the Stroke geometry so that it looks more "polygonal". The basic idea is to start from the minimal stroke approximation consisting in a line joining the first vertex to the last one and to subdivide using the original stroke vertices until a certain error is reached.

Constructor & Destructor Documentation

◆ PolygonalizationShader()

Freestyle::StrokeShaders::PolygonalizationShader::PolygonalizationShader ( float iError )

inline

Builds the shader.

Parameters

iError The error we want our polygonal approximation to have with respect to the original geometry. The smaller, the closer the new stroke to the original one. This error corresponds * to the maximum distance between the new stroke and the old one.
