Appearance - CesiumJS API 文档

new Cesium.Appearance(options)

外观定义了完整的顶点和片段阴影以及 render state used to draw a Primitive. All appearances implement 此基础为 Appearance 接口.

Name Type Description

options

object

optional 下列属性的对象 :

Name	Type	Default	Description
`translucent`	boolean	`true`	optional When `true`, the geometry is expected to appear translucent so `Appearance#renderState` has alpha blending enabled.
`closed`	boolean	`false`	optional When `true`, the geometry is expected to be closed so `Appearance#renderState` has backface culling enabled.
`material`	Material	`Material.ColorType`	optional The material used to determine the fragment color.
`vertexShaderSource`	string		optional 可选 NT 0 顶点阴影源,以覆盖默认顶点阴影源.
`fragmentShaderSource`	string		optional 可选的 NT 0 碎片遮蔽源以覆盖默认的碎片遮蔽源 .
`renderState`	object		optional 可选的渲染状态来推翻默认渲染状态 .

Members

readonly closed : boolean

当 NT 0 real NT 1 时,几何学有望关闭.

Default Value: false

readonly fragmentShaderSource : string

The GLSL source code for the fragment shader. The full fragment shader source is built procedurally taking into account the Appearance#material. 使用 Appearance#getFragmentShaderSource 获得完整来源.

material : Material

The material used to determine the fragment color. Unlike other Appearance 属性,这不是只读的,所以一个外观的材料可以在苍蝇上改变.

See:

Fabric

readonly renderState : object

The WebGL fixed-function state to use when rendering the geometry.

translucent : boolean

当 ret 时,几何形似半透明.

Default Value: true

readonly vertexShaderSource : string

顶点遮蔽器的 GLSL 源代码.

Methods

getFragmentShaderSource() → string

在程序上为这一外观创建完整的 NT 0 碎片遮蔽源 taking into account Appearance#fragmentShaderSource and Appearance#material.

Returns:

The full GLSL fragment shader source.

getRenderState() → object

创建渲染状态。这不是最终的州法院;相反, 它可以包含一个子集,与渲染状态相同的渲染状态属性在上下文中创建.

Returns:

铸造状态.

isTranslucent() → boolean

Determines if the geometry is translucent based on Appearance#translucent and Material#isTranslucent.

Returns:

如果外观为半透明,则使用# 真 .
