详细描述

Derived cluster cache that incrementally executes a BuildLayerStack.

Grid hashes include a one-cell halo so tile-side geometry is invalidated when a neighboring cluster changes. Point ownership follows the source point's half-open world-space cluster. Updates are transactional and preserve the old cache on failure. @thread Affine; update and query on the owning thread.

成员函数说明

◆ clear()

void eve::procgen::IncrementalBuildExecutor::clear ( )

Clears .

在文件 IncrementalBuild.cpp 第 218 行定义.

被这些函数引用 eve::procgen::exposeGridMeshGraphs().

◆ getCachedArtifacts()

Result< BuildLayerExecution > eve::procgen::IncrementalBuildExecutor::getCachedArtifacts	(	int	clusterX,
		int	clusterZ
	)		const

Returns the cached artifacts.

在文件 IncrementalBuild.cpp 第 221 行定义.

引用了 eve::Diagnostic::error(), eve::Result< T >::failure(), found, eve::NotFound , 以及 eve::Result< T >::success().

◆ getCachedClusterCount()

int eve::procgen::IncrementalBuildExecutor::getCachedClusterCount ( ) const

noexcept

Returns the cached cluster count.

在文件 IncrementalBuild.cpp 第 219 行定义.

◆ update()

Result< IncrementalBuildDelta > eve::procgen::IncrementalBuildExecutor::update	(	const BuildLayerStack &	stack,
		const Grid2D &	grid,
		const PointSet &	points,
		int	clusterSizeCells,
		float	cellSizeWorld,
		const PointSet *	orientation = `nullptr`
	)

Rebuild only clusters whose layer definition, grid halo, point rows or orientation changed.

参数

stack	Authoritative ordered layer definitions.
grid	Authoritative tile source.
points	Authoritative object placement source.
clusterSizeCells	Positive square cluster extent in grid cells.
cellSizeWorld	Positive world-space size of one grid cell.
orientation	Optional object orientation layer; changes invalidate all active clusters.

返回: Deterministically ordered upsert/removal delta. Empty means the cache was already current. @cost O(grid cells + points + dirty cluster build cost); unchanged artifacts are copied only by cache ownership.

在文件 IncrementalBuild.cpp 第 160 行定义.

引用了 active, eve::procgen::Semantic::Empty, eve::Diagnostic::error(), eve::procgen::BuildLayerStack::executeRegion(), eve::Result< T >::failure(), hash, eve::InvalidArgument, key, point, points, previous, eve::Result< T >::success(), x , 以及 y.
