详细描述

Immutable regularly sampled heightfield usable as an XY or XZ placement surface.

在文件 HeightfieldSurface.h 第 16 行定义.

成员函数说明

◆ config()

const Config & eve::building::HeightfieldSurface::config ( ) const
inline

Return the immutable construction configuration.

在文件 HeightfieldSurface.h 第 54 行定义.

◆ create()

eve::Result< std::shared_ptr< const HeightfieldSurface > > eve::building::HeightfieldSurface::create ( Config  config,
std::vector< float >  samples 
)
static

Validate and take ownership of an immutable heightfield.

参数
configDimensions, plane-space transform and stable surface identity.
samplesRow-major samples; exactly width * height finite values are required.
返回
A shareable immutable surface or a structured validation failure.

◆ sample()

eve::Result< PlacementSystem::PlacementHit > eve::building::HeightfieldSurface::sample ( const PlacementWorld &  world,
float  planeX,
float  planeY 
) const

Bilinearly sample height and its continuous local differential frame.

参数
worldSupplies whether plane coordinates map to world XY or XZ.
planeXFirst grid-plane coordinate.
planeYSecond grid-plane coordinate.
返回
An owning hit, or NotFound when the coordinate is outside the heightfield. @thread Safe to call concurrently after construction. No callbacks are invoked.
