Масгрейв – Musgrave

The musgrave texture is used to generate organic materials, but it is very flexible. You can do nearly everything with it.

Type – Тип

This procedural texture has five noise types on which the resulting pattern can be based and they are selectable from a select menu at the top of the tab. The five types are:

• Гетеро Місцевість – Hetero Terrain

• Фрактальний Броунівський Рух – Fractal Brownian Motion (fBm)

• Гібрид Мультифрактал – Hybrid Multifractal

• Загострений Мультифрактал – Ridged Multifractal

• Мультифрактал – Multifractal

Ці типи шуму визначають спосіб, яким Blender’а нашаровує послідовні копії однакового патерну один поверх іншого, варіюючи контраст та масштаб.

Приклади з уставами Basis: Voronoi: F1, Dimension: 0.5, Lacunarity: 0.15, Octave: 2.0.

Головні типи шуму мають чотири характеристики:

Розмір – Dimension

Fractal dimension controls the contrast of a layer relative to the previous layer in the texture. The higher the fractal dimension, the higher the contrast between each layer, and thus the more detail shows in the texture.

Лакунарність – Lacunarity

Lacunarity controls the scaling of each layer of the Musgrave texture, meaning that each additional layer will have a scale that is the inverse of the value which shows on the button. i.e. Lacunarity = 2 –> Scale = 1/2 original.

Октави – Octaves

Octave controls the number of times the original noise pattern is overlaid on itself and scaled/contrasted with the fractal dimension and lacunarity settings.

Intensity – Інтенсивність

Light intensity. Called Offset for Hetero Terrain.

Типи Hybrid Multifractal та Ridged Multifractal мають такі додаткові устави:

Offset – Зсув

Both have a «Fractal Offset» button that serves as a «sea level» adjustment and indicates the base height of the resulting bump map. Bump values below this threshold will be returned as zero.

Gain – Підсил

Setting which determines the range of values created by the function. The higher the number, the greater the range. This is a fast way to bring out additional details in a texture where extremes are normally clipped off.
