详细描述

Separable Gaussian depth-of-field for the final HDR scene.

Reads linear HDR color plus hardware depth (Vulkan NDC z). Blur radius grows with view-space distance from focusDistance over focusRange, capped at maxBlurPx. Zero max blur is a no-op. Used by HD-2D miniature looks; sprites must write depth (masked/cutout) so characters stay sharp in the focus band.

成员函数说明

apply()

Texture * eve::graphics::DepthOfField::apply	(	Texture *	source,
		Texture *	hwDepth,
		float	focusDistance,
		float	maxBlurPx,
		float	focusRange,
		float	nearZ,
		float	farZ
	)

Apply separable Gaussian DOF.

参数

source	Linear HDR scene color.
hwDepth	Hardware depth (NDC z in .r). Null disables the effect.
focusDistance	View-space focus plane distance.
maxBlurPx	Maximum blur radius in source texels; <= 0 disables.
focusRange	Distance from focus at which blur reaches maxBlurPx.
nearZ	Camera near clip.
farZ	Camera far clip.

返回

Blurred HDR texture owned by this DepthOfField, or source when disabled. @lifetime Returned texture remains valid until dimensions change or this object is destroyed.
