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.
See the base Material class for common properties.
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.
The red channel of this texture is used as the ambient occlusion map. Default is null. The aoMap requires a second set of UVs.
Intensity of the ambient occlusion effect. Default is 1. Zero is no occlusion effect.
The texture to create a bump map. The black and white values map to the perceived depth in relation to the lights. Bump doesn't actually affect the geometry of the object, only the lighting. If a normal map is defined this will be ignored.
How much the bump map affects the material. Typical ranges are 0-1. Default is 1.
Color of the material, by default set to white (0xffffff).
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.
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.
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.
Emissive (light) color of the material, essentially a solid color unaffected by other lighting. Default is black.
Set emisssive (glow) map. Default is null. The emissive map color is modulated by the emissive color and the emissive intensity. If you have an emissive map, be sure to set the emissive color to something other than black.
Intensity of the emissive light. Modulates the emissive color. Default is 1.
Gradient map for toon shading. It's required to set Texture.minFilter and Texture.magFilter to v3d.NearestFilter when using this type of texture. Default is null.
The light map. Default is null. The lightMap requires a second set of UVs.
Intensity of the baked light. Default is 1.
The color map. Default is null. The texture map color is modulated by the diffuse .color.
Defines whether the material uses morphNormals. Set as true to pass morphNormal attributes from the Geometry to the shader. Default is false.
Define whether the material uses morphTargets. Default is false.
The texture to create a normal map. The RGB values affect the surface normal for each pixel fragment and change the way the color is lit. Normal maps do not change the actual shape of the surface, only the lighting. In case the material has a normal map authored using the left handed convention, the y component of normalScale should be negated to compensate for the different handedness.
The type of normal map.
Options are v3d.TangentSpaceNormalMap (default), and v3d.ObjectSpaceNormalMap.
How much the normal map affects the material. Typical ranges are 0-1. Default is a Vector2 set to (1,1).
Define whether the material uses skinning. Default is false.
Render geometry as wireframe. Default is false (i.e. render as flat polygons).
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.
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.
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.
