|
|
|
+ <p class="desc"> 一种用于非光泽表面的材质，没有镜面高光。<br /><br />
|
|
|
+ 该材质使用基于非物理的[link:https://en.wikipedia.org/wiki/Lambertian_reflectance Lambertian]模型来计算反射率。
|
|
|
+ 这可以很好地模拟一些表面（例如未经处理的木材或石材），但不能模拟具有镜面高光的光泽表面（例如涂漆木材）。<br /><br />
|
|
|
|
|
|
- The material uses a non-physically based [link:https://en.wikipedia.org/wiki/Lambertian_reflectance Lambertian]
|
|
|
- model for calculating reflectance. This can simulate some surfaces (such as untreated wood or stone) well,
|
|
|
- but cannot simulate shiny surfaces with specular highlights (such as varnished wood).<br /><br />
|

|
|
-
|
|
|
- Shading is calculated using a [link:https://en.wikipedia.org/wiki/Gouraud_shading Gouraud] shading model.
|
|
|
- This calculates shading per vertex (i.e. in the [link:https://en.wikipedia.org/wiki/Shader#Vertex_shaders vertex shader])
|
|
|
- and interpolates the results over the polygon's faces.<br /><br />
|
|
|
-
|
|
|
- Due to the simplicity of the reflectance and illumination models, performance will be greater
|
|
|
- when using this material over the [page:MeshPhongMaterial], [page:MeshStandardMaterial] or [page:MeshPhysicalMaterial],
|
|
|
- at the cost of some graphical accuracy.

+ 使用[link:https://en.wikipedia.org/wiki/Gouraud_shading Gouraud]着色模型计算着色。
|

|
+ 这将计算每个顶点的着色（如在[link:https://en.wikipedia.org/wiki/Shader#Vertex_shaders vertex shader]中）并在多边形的面上插入结果。<br /><br />
|
|
|
+ 由于反射率和光照模型的简单性，[page:MeshPhongMaterial]，[page:MeshStandardMaterial]或者[page:MeshPhysicalMaterial]

|
|
|
- For RGB and RGBA textures, the [page:WebGLRenderer 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

|
+ 仅使用纹理的颜色，忽略alpha通道（如果存在）。对于RGB和RGBA纹理，[page:WebGLRenderer WebGL]渲染器在采样此纹理时将使用绿色通道，
|
|
|
+ 因为在DXT压缩和未压缩RGB 565格式中为绿色提供了额外的精度。单亮度以及亮度/alpha纹理也仍然有效。
