Detailed Description

Mesh parameterizations/UV maps.

Function Documentation

LStretch()

LStretchMetrics volcart::texturing::LStretch	(	const ITKMesh::Pointer &	mesh3D,
		const ITKMesh::Pointer &	mesh2D
	)

Calculate the L2 and LInf stretch between a 2D and 3D mesh.

Calculates the L2 and LInf stretch norms from "Texture Mapping Progressive Meshes" by Sander et al. [sander2001texture]. See LStretchMetrics for more info on these metrics. Meshes are assumed to be pre-scaled to have the same surface area.

PlotLStretchError()

std::vector< cv::Mat > volcart::texturing::PlotLStretchError	(	const LStretchMetrics &	metrics,
		const cv::Mat &	cellMap,
		ColorMap	cm = ColorMap::Plasma,
		bool	drawLegend = false
	)

Plot per-face L stretch error metrics.

This function maps per-face LStretchMetrics to a 2D image using the provided cell map. If drawLegend is true, a legend bar will be appended to the bottom of the image showing the metric label, global metric, and color map scale bar.

PlotPerFaceError()

template<typename ErrContainer >

cv::Mat volcart::texturing::PlotPerFaceError	(	const cv::Mat &	cellMap,
		const ErrContainer &	errorMap,
		float	defaultValue = 0
	)

Plot generic per-face error information into an image.

Template Parameters

ErrContainer

Container type supporting the .at() accessor. Return values must support static_cast to float.

Parameters

cellMap	Cell map image produced by PPMGenerator or GenerateCellMap
errorMap	Container of per-face error values
defaultValue	Default pixel value if it doesn't have a cell mapping

Returns

Image of error plot with type CV_32FC1
