Function Documentation

geodesic_dilation()

template<typename Scalar, typename Index, typename ValueType>

void geodesic_dilation	(	const SurfaceMesh< Scalar, Index > &	mesh,
		image::experimental::View3D< ValueType >	texture,
		const DilationOptions &	options = {} )

#include <lagrange/texproc/geodesic_dilation.h>

Extend pixels of a texture beyond the defined UV mesh by walking along the 3D surface.

Parameters

[in]	mesh	Input mesh with UV attributes.
[in,out]	texture	Texture to extend beyond UV mesh boundaries, or where to write the output position map. When writing a position map, the texture must have 3 channels.
[in]	options	Dilation options.

Template Parameters

Scalar	Mesh scalar type.
Index	Mesh index type.
ValueType	Image value type.

texture_compositing()

template<typename Scalar, typename Index, typename ValueType>

image::experimental::Array3D< ValueType > texture_compositing	(	const SurfaceMesh< Scalar, Index > &	mesh,
		std::vector< ConstWeightedTextureView< ValueType > >	textures,
		const CompositingOptions &	options = {} )

#include <lagrange/texproc/texture_compositing.h>

Composite multiple textures into a single texture.

Parameters

[in]	mesh	Input mesh with UV attributes.
[in]	textures	Textures to composite. Input textures must have the same dimensions.
[in]	options	Compositing options.

Template Parameters

Scalar	Mesh scalar type.
Index	Mesh index type.
ValueType	Texture value type.

Returns

Texture image resulting from the compositing.

texture_filtering()

template<typename Scalar, typename Index, typename ValueType>

void texture_filtering	(	const SurfaceMesh< Scalar, Index > &	mesh,
		image::experimental::View3D< ValueType >	texture,
		const FilteringOptions &	options = {} )

#include <lagrange/texproc/texture_filtering.h>

Smooth or sharpen a texture image associated with a mesh.

Parameters

[in]	mesh	Input mesh with UV attributes.
[in,out]	texture	Texture image to filter.
[in]	options	Filtering options.

Template Parameters

Scalar	Mesh scalar type.
Index	Mesh index type.
ValueType	Texture value type.

texture_stitching()

template<typename Scalar, typename Index, typename ValueType>

void texture_stitching	(	const SurfaceMesh< Scalar, Index > &	mesh,
		image::experimental::View3D< ValueType >	texture,
		const StitchingOptions &	options = {} )

#include <lagrange/texproc/texture_stitching.h>

Stitch the seams of a texture associated with a mesh.

Parameters

[in]	mesh	Input mesh with UV attributes.
[in,out]	texture	Texture to stitch.
[in]	options	Stitching options.

Template Parameters

Scalar	Mesh scalar type.
Index	Mesh index type.
ValueType	Image value type.

filter_low_confidences()

void filter_low_confidences	(	span< std::pair< image::experimental::Array3D< float >, image::experimental::Array3D< float > > >	textures_and_weights,
		float	low_ratio_threshold )

#include <lagrange/texproc/TextureRasterizer.h>

Discard low-confidence values.

Texels whose weight is < threshold * max_weight are set to zero.

Parameters

[in,out]	textures_and_weights	A list of compute texture and confidence images.
[in]	low_ratio_threshold	Threshold for discarding low-confidence texels.
