A material for drawing geometry by depth. Depth is based off of the camera near and far plane. White is nearest, black is farthest.


MeshDepthMaterial(parameters : Object)

parameters - (optional) an object with one or more properties defining the material's appearance. Any property of the material (including any property inherited from Material) can be passed in here.


See the base Material class for common properties.

.alphaMap : Texture

The alpha map is a grayscale texture that controls the opacity across the surface (black: fully transparent; white: fully opaque). Default is null.

Only the color of the texture is used, ignoring the alpha channel if one exists. For RGB and RGBA textures, the WebGL renderer will use the green channel when sampling this texture due to the extra bit of precision provided for green in DXT-compressed and uncompressed RGB 565 formats. Luminance-only and luminance/alpha textures will also still work as expected.

.depthPacking : Constant

Encoding for depth packing. Default is BasicDepthPacking.

.displacementMap : Texture

The displacement map affects the position of the mesh's vertices. Unlike other maps which only affect the light and shade of the material the displaced vertices can cast shadows, block other objects, and otherwise act as real geometry. The displacement texture is an image where the value of each pixel (white being the highest) is mapped against, and repositions, the vertices of the mesh.

.displacementScale : Float

How much the displacement map affects the mesh (where black is no displacement, and white is maximum displacement). Without a displacement map set, this value is not applied. Default is 1.

.displacementBias : Float

The offset of the displacement map's values on the mesh's vertices. Without a displacement map set, this value is not applied. Default is 0.

.fog : Boolean

Whether the material is affected by fog. Default is false.

.map : Texture

The color map. Default is null.

.morphTargets : boolean

Define whether the material uses morphTargets. Default is false.

.skinning : Boolean

Define whether the material uses skinning. Default is false.

.slopeScaledBias : Number

An adaptive bias which depends on the polygon's slope relative to the camera. Applied only if .useSlopeScaledBias is set to true. Default is 0.

Used mainly for shadow mapping.

.useSlopeScaledBias : Boolean

Enables or disables .slopeScaledBias. Default is false.

Used mainly for shadow mapping.

.wireframe : boolean

Render geometry as wireframe. Default is false (i.e. render as smooth shaded).

.wireframeLinewidth : Float

Controls wireframe thickness. Default is 1.

Due to limitations of the OpenGL Core Profile with the WebGL renderer on most platforms linewidth will always be 1 regardless of the set value.
