Description#

Map a color based on ray incidence angle to the surface.

Public Attributes#

Type	Name	Visual Hint	Description
`double[3]`	`front`	`VISUAL_HINT_COLOR`	Mapped color when the angle between the ray and the surface is 0
`double[3]`	`rim`	`VISUAL_HINT_COLOR`	Mapped color when the angle between the ray and the surface is 90
`double`	`normal_input`	`VISUAL_HINT_PERCENTAGE`	Override the shading normal by the one given as input. The value controls the blending with the original normal.
`reference` (`SceneItem`)	`locator`	`VISUAL_HINT_DEFAULT`	Define an object to use instead of the ray to compute the angle.
`double`	`exponent`	`VISUAL_HINT_PERCENTAGE`	Mapping falloff exponent. 100% is linear, 200% is quadratic, 300% is cubic...

Inherited Public Attributes#

Type	Name	Visual Hint	Description
`bool`	`pass_through`	`VISUAL_HINT_DEFAULT`	If checked, the current texture is not evaluated and the value of the attribute selected in Pass Through Attribute is directly forwarded.
`string`	`master_input`	`VISUAL_HINT_TAG`	Name of the attribute that will be used as output if Pass Through is enabled.
`bool`	`invert`	`VISUAL_HINT_DEFAULT`	If checked, the texture is inverted.
`double`	`opacity`	`VISUAL_HINT_PERCENTAGE`	Set the opacity of the texture.
