Узел «Текстура „Масгрейв“»

Примечание

This node is ported from shader nodes. The manual and images are referencing the shader version of the node. This node accepts field inputs and outputs. When not connected the Vector input has an implicit position attribute value.

Узел «Текстура „Масгрейв“»

The Musgrave Texture node evaluates a fractal Perlin noise at the input texture coordinates. Unlike the Noise Texture, which is also a fractal Perlin noise, the Musgrave Texture allows greater control over how octaves are combined.

Входы

The inputs are dynamic, they become available if needed depending on the node properties.

Вектор

Texture coordinate to evaluate the noise at; defaults to Generated texture coordinates if the socket is left unconnected.

W

Texture coordinate to evaluate the noise at.

Масштаб

Scale of the base noise octave.

Детальность

Number of noise octaves. The fractional part of the input is multiplied by the magnitude of the highest octave. Higher number of octaves corresponds to a higher render time.

Размерность

The difference between the magnitude of each two consecutive octaves. Larger values corresponds to smaller magnitudes for higher octaves.

Лакунарность

The difference between the scale of each two consecutive octaves. Larger values corresponds to larger scale for higher octaves.

Offset

An added offset to each octave, determines the level where the highest octave will appear.

Насыщенность

An extra multiplier to tune the magnitude of octaves.

Свойства

Dimensions

The dimensions of the space to evaluate the noise in.

1D

Evaluate the noise in 1D space at the input W.

2D

Evaluate the noise in 2D space at the input Vector. The Z component is ignored.

3D

Evaluate the noise in 3D space at the input Vector.

4D

Evaluate the noise in 4D space at the input Vector and the input W as the fourth dimension.

Higher dimensions corresponds to higher render time, so lower dimensions should be used unless higher dimensions are necessary.

Type

Type of the Musgrave texture.

FBM (Fractal Brownian Motion)

Produces an unnatural homogeneous and isotropic result. Uses an additive cascade, the values are simply added together.

Multifractal

The result is more uneven (varies with location), more similar to a real terrain. Uses a multiplicative cascade.

Hybrid Multifractal

Creates peaks and valleys with different roughness values, like real mountains rise out of flat plains. Combines the additive cascade with a multiplicative cascade.

Ridged Multifractal

Creates sharp peaks. Calculates the absolute value of the noise, creating «canyons», and then flips the surface upside down.

Hetero Terrain (Heterogeneous Terrain)

Similar to Hybrid Multifractal creates a heterogeneous terrain, but with the likeness of river channels.

Выходы

Высота

Texture value.
