Gaussian Spectrum

This output uses a Gaussian distribution spectrum. Wavelength sets the center of the spectrum, and Width sets the curve width. The narrower the Width, the more pure and saturated the color (Figure 1).

Gaussian Spectrum Parameters

• Wavelength - This represents the mean wavelength approximation between 380 nm – 720 nm (with a range from 0 - 1). Lower values appear bluish, and higher values (around 700 nm) appear reddish.
• Width - When set to 0, almost no color is visible. When set to 1, the color spreads thin over a large space, and the texture appears faint.
• Power - The texture brightness.
