Material

MeshBasicMaterial

A material for drawing geometries in a simple shaded (flat or wireframe) way.

This material is not affected by lights.

Constructor

MeshBasicMaterial

function MeshBasicMaterial( parameters: Object ): void;  

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.

The exception is the property color, which can be passed in as a hexadecimal string and is 0xffffff (white) by default. Color.set( color ) is called internally.

Properties

See the base Material class for common properties.

alphaMap

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.

aoMap

aoMap: Texture;  

The red channel of this texture is used as the ambient occlusion map. Default is null. The aoMap requires a second set of UVs.

aoMapIntensity

aoMapIntensity: Float;  

Intensity of the ambient occlusion effect. Default is 1. Zero is no occlusion effect.

color

color: Color;  

Color of the material, by default set to white (0xffffff).

combine

combine: Integer;  

How to combine the result of the surface's color with the environment map, if any.

Options are .aterials (default), .aterials, .aterials. If mix is chosen, the .reflectivity is used to blend between the two colors.

envMap

envMap: Texture;  

The environment map. Default is null.

fog

fog: Boolean;  

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

lightMap

lightMap: Texture;  

The light map. Default is null. The lightMap requires a second set of UVs.

lightMapIntensity

lightMapIntensity: Float;  

Intensity of the baked light. Default is 1.

map

map: Texture;  

The color map. May optionally include an alpha channel, typically combined with .transparent or .alphaTest. Default is null.

reflectivity

reflectivity: Float;  

How much the environment map affects the surface; also see .combine. The default value is 1 and the valid range is between 0 (no reflections) and 1 (full reflections).

refractionRatio

refractionRatio: Float;  

The index of refraction (IOR) of air (approximately 1) divided by the index of refraction of the material. It is used with environment mapping modes THREE.CubeRefractionMapping and THREE.EquirectangularRefractionMapping. The refraction ratio should not exceed 1. Default is 0.98.

specularMap

specularMap: Texture;  

Specular map used by the material. Default is null.

wireframe

wireframe: Boolean;  

Render geometry as wireframe. Default is false (i.e. render as flat polygons).

wireframeLinecap

wireframeLinecap: String;  

Define appearance of line ends. Possible values are "butt", "round" and "square". Default is 'round'.

This corresponds to the 2D Canvas lineCap property and it is ignored by the WebGL renderer.

wireframeLinejoin

wireframeLinejoin: String;  

Define appearance of line joints. Possible values are "round", "bevel" and "miter". Default is 'round'.

This corresponds to the 2D Canvas lineJoin property and it is ignored by the WebGL renderer.

wireframeLinewidth

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.
