A material that maps the normal vectors to RGB colors.
[page: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 [page:Material]) can be passed in here.
See the base [page:Material] class for common properties.
Whether the material is affected by fog. Default is *false*.
Used to check whether this or derived classes are mesh normal materials. Default is *true*.
You should not change this, as it used internally for optimisation.
Whether the material is affected by lights. Default is *false*.
Define whether the material uses morphTargets. Default is false.
Render geometry as wireframe. Default is false (i.e. render as smooth shaded).
Controls wireframe thickness. Default is 1.
Due to limitations of the [link:https://www.khronos.org/registry/OpenGL/specs/gl/glspec46.core.pdf OpenGL Core Profile]
with the [page:WebGLRenderer WebGL] renderer on most platforms linewidth will
always be 1 regardless of the set value.
See the base [page:Material] class for common methods.
