This tab allows you to control the shading parameters
without having to apply extra material. These parameters can be used
only if any of the Shading modes are activated in the View
toolbar. This tab deals
with the options concerning:
|
|
General parameters
|
|
|
|
Deactivate ambient lighting
This option has effect on the standard shading as well as the material. |
|
By default, this option is cleared. |
|
Default Shading Material parameters
|
|
These options have impact on the shading visualization. However, the
material visualization will not be affected by these options. |
|
Ambient & Diffuse coefficient |
|
Ambient:
Defines the intensity of light diffused in any direction by the
object, even if not lit by any light source. You can enter a value
comprised between 0 and 1 for this coefficient. |
|
Diffuse:
defines the intensity of light diffused by the object when lit by
light sources. You can enter a value comprised between 0 and 1. |
|
Its default value is set to 1. |
|
Specular coefficient
|
|
Specular:
Defines the intensity and color of light reflected in one
particular direction (highlights).
Typically, a polished object would have a high value for the specular
reflectance coefficient, while a more mat surface would have a lower
one. |
|
Its default value is set to 1. |
|
Roughness coefficient
|
|
Roughness:
Defines the dullness of the object, i.e. the size of the
reflecting zone.
Set the value to a minimum to generate very sharp highlights on very
shiny surfaces. Set the roughness to a higher value to generate large
specular spots creating a duller effect on rougher surfaces. |
|
Its default value is set to 0.41. |
