== Global Array Node ==
== HSV to RGB Node ==


The Global Array node creates and accesses a global array. Array's type, size and name can be configured via its [[#paramType|Type]], [[#paramArrayLength|Array Length]] and [[#paramName|Name]] respective options.
The HSV to RGB node converts a value from an HSV to a RGB color space.
RGB color space is defined by three separate channels:
* '''R:''' First channel defines the amount of red in the color
* '''G:''' Second channel defines the amount of green in the color
* '''B:''' Third channel defines the amount of blue in the color

As for the HSV color space, it represents color in a cylinder and also contains three separate channels but each one as a completely different meaning
* '''Hue:''' First channel defines the color itself as an angle on a color cylinder 
* '''Saturation:''' Second channel defines amount of gray in the color as a distance across a color cylinder radius
* '''Value:''' Third channel defines brightness/intensity of the color as a distance across a color cylinder height

HSV to RGB Node

The HSV to RGB node converts a value from an HSV to a RGB color space. RGB color space is defined by three separate channels:

  • R: First channel defines the amount of red in the color
  • G: Second channel defines the amount of green in the color
  • B: Third channel defines the amount of blue in the color

As for the HSV color space, it represents color in a cylinder and also contains three separate channels but each one as a completely different meaning

  • Hue: First channel defines the color itself as an angle on a color cylinder
  • Saturation: Second channel defines amount of gray in the color as a distance across a color cylinder radius
  • Value: Third channel defines brightness/intensity of the color as a distance across a color cylinder height


Nodes used: World Position, Float, HSV to RGB

Node Parameter Description Default Value
Hue Color itself, represents an angle on the HSV cylindrical model.

Only visible if the respective input port is not connected.

0
Saturation Amount of gray in the color, represents a distance across the HSV cylindrical model radius.

Only visible if the respective input port is not connected.

0
Value Brightness/Intensity of the color, represents a distance across the HSV cylindrical model height.

Only visible if the respective input port is not connected.

0
Precision Defines the amount of bytes the variable can hold, effectively defining how precise the value is. It's usefulness is bond by the hardware specifications necessary. Lowest precision is slightly faster but might produce errors and artifacts.
  • Float: Highest precision, useful for values that can be very high or very low in value (ie: positions, coordinates, etc)
  • Half: Medium precision, in most cases is as good as Float but at half of it's precision
  • Inherit: Use global precision set on master node properties
