PackOptions Struct Reference

Packing options. More...

#include <lagrange/xatlas/Options.h>

Public Attributes
uint32_t	max_chart_size = 0
	Maximum chart size, in pixels.
uint32_t	padding = 0
	Empty pixels of padding to leave around each chart. Useful for mip-map filtering.
float	texels_per_unit = 0.f
	Texel-to-world-unit ratio.
uint32_t	resolution = 0
	Atlas tile resolution, in pixels (square).
bool	bilinear = true
	If true, leave a 1-pixel safety margin so bilinear filtering doesn't sample neighbouring charts.
bool	block_align = false
	If true, align charts to 4-pixel blocks (useful for compressed texture formats like BCn).
bool	brute_force = false
	If true, use brute-force search to find optimal chart placement (significantly slower).
bool	rotate_charts_to_axis = true
	If true, rotate each chart so that its longest principal axis aligns with the U or V axis.
bool	rotate_charts = true
	If true, allow xatlas to rotate charts during packing (in addition to axis alignment).

Member Data Documentation

max_chart_size

uint32_t max_chart_size = 0

Maximum chart size, in pixels.

Charts larger than this are scaled down. 0 (default) means no limit.

texels_per_unit

float texels_per_unit = 0.f

Texel-to-world-unit ratio.

If 0, xatlas estimates a value such that the entire atlas fits within resolution x resolution (or a single tile of any size if resolution is also 0).

resolution

uint32_t resolution = 0

Atlas tile resolution, in pixels (square).

0 (default) means a single atlas sized by texels_per_unit. If both are non-zero, charts that don't fit produce additional tiles.
