构造及析构函数说明

DepthPyramid()

eve::graphics::DepthPyramid::DepthPyramid ( Graphics *  gfx )

explicit

Create the depth reduction shader.

成员函数说明

build()

Texture * eve::graphics::DepthPyramid::build	(	Texture *	depth,
		int	maxLevels = 8
	)

Build the min/max hierarchy from a hardware depth texture.

参数

depth	Hardware depth source, near=0 and far=1.
maxLevels	Maximum hierarchy levels to build for the active quality budget.

返回

RG min/max depth atlas; level zero starts at x=0 and each lower level is packed directly to the right of its predecessor. @lifetime The returned texture is owned by this DepthPyramid until the next target resize.

在文件 DepthPyramid.cpp 第 75 行定义.

引用了 eve::graphics::Canvas::clear(), depth, eve::graphics::Graphics::drawTexturedRectShaderUV(), eve::graphics::Graphics::getCanvas(), eve::graphics::Canvas::getTexture(), input, level, offsetX, eve::Opaque, eve::graphics::Shader::sendFloat(), eve::graphics::Graphics::setCanvas(), source , 以及 target.

被这些函数引用 eve::graphics::RenderSystem3D::render().

getLevelCount()

int eve::graphics::DepthPyramid::getLevelCount ( ) const

inline

Number of valid levels in the last build.

在文件 DepthPyramid.h 第 29 行定义.

被这些函数引用 eve::graphics::RenderSystem3D::render().

getSourceHeight()

int eve::graphics::DepthPyramid::getSourceHeight ( ) const

inline

Source depth height represented by level zero.

在文件 DepthPyramid.h 第 33 行定义.

getSourceWidth()

int eve::graphics::DepthPyramid::getSourceWidth ( ) const

inline

Source depth width represented by level zero.

在文件 DepthPyramid.h 第 31 行定义.
