详细描述

Maps world-space density into a camera froxel volume and integrates it.

Occupancy skipping and temporal history follow the active FogQualityBudget.

在文件 FogFroxelBridge.h 第 24 行定义.

成员函数说明

inject()

Result< int > eve::graphics::fog::FogFroxelBridge::inject	(	AtmosphereVolume &	volume,
		const FogDensityField &	field,
		const FogProfile &	profile,
		const glm::mat4 &	invViewProj,
		bool	occupancySkip
	)

Inject density-field media into an AtmosphereVolume froxel grid.

参数

invViewProj	Inverse view-projection used to reconstruct froxel centers.
occupancySkip	Skip empty froxels when the quality budget allows it.

返回

Number of froxels that received non-zero media.

integrate()

Result< void > eve::graphics::fog::FogFroxelBridge::integrate	(	AtmosphereVolume &	volume,
		const FogDensityField &	field,
		const FogProfile &	profile,
		const glm::mat4 &	invViewProj,
		const glm::vec3 &	lightDir,
		const glm::vec3 &	lightColor,
		float	intensity,
		const BeerLightCache *	beerCache
	)

Integrate froxels with optional Beer-cache visibility.

参数

invViewProj

Inverse view-projection; must match the matrix used by inject().
