Detailed Description

Gradient atlas — caches evaluated gradient ramps as GPU textures.

Gradients are keyed by a hash of their stops/colors.

Member Function Documentation

allocate()

bool pulp::render::GradientAtlas::allocate	(	uint64_t	key,
		int &	row )

entry_count()

size_t pulp::render::GradientAtlas::entry_count ( ) const

inline

evict_stale()

size_t pulp::render::GradientAtlas::evict_stale	(	uint64_t	current_frame,
		uint64_t	max_age = 120 )

has()

bool pulp::render::GradientAtlas::has ( uint64_t key ) const

inline

mark_used()

void pulp::render::GradientAtlas::mark_used	(	uint64_t	key,
		uint64_t	frame )

occupancy()

float pulp::render::GradientAtlas::occupancy ( ) const

inline

row_capacity()

int pulp::render::GradientAtlas::row_capacity ( ) const

inline

Read-only introspection for the inspector's atlas viewer.

A GradientAtlas is row-packed (one ramp per row) rather than shelf-packed, so occupancy is simply allocated rows over the row budget.

rows_used()

int pulp::render::GradientAtlas::rows_used ( ) const

inline
