PhysicalNoise Class
Warning
The scope of applications for UnigineScript is limited to implementing materials-related logic (material expressions, scriptable materials, brush materials). Do not use UnigineScript as a language for application logic, please consider C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScipt (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.

A PhysicalNoise class is used to simulate a force field affecting physical bodies and particles based on a volumetric noise texture. It creates an additional distribution flow specifying the force and the displacement direction for bodies and particles at each point of the force field.
Notice
Usage Example#
In this example a physical noise node and 50 boxes, each with a body and a shape, are created. Generated boxes fall down under the set gravity and are affected by the physical noise as they get into it.

PhysicalNoise Class
Members
static PhysicalNoise ( vec3 size ) #
Constructor. Creates a physical noise node of the specified size.Arguments
- vec3 size - Physical noise box size in units.
void setForce ( float force ) #
Sets the value of the force multiplier.Arguments
- float force - Force multiplier. The higher the value is, the higher the value of the resulting force that affects an object inside the physical noise node will be.
float getForce ( ) #
Returns the value of the force multiplier.Return value
Force multiplier. The higher the value is, the higher the value of the resulting force that affects an object inside the physical noise node will be.void setFrequency ( int frequency ) #
Sets the number of octaves for the Perlin noise texture generation.Notice
It is not recommended to change this parameter in run-time as the noise texture will be regenerated and the performance will decrease.
Arguments
- int frequency - Number of octaves for the Perlin noise texture generation. The minimum value is 1, the maximum value is 16. The higher the value is, the more details the noise texture has.
int getFrequency ( ) #
Returns the number of octaves for the Perlin noise texture generation.Notice
It is not recommended to change this parameter in run-time as the noise texture will be regenerated and the performance will decrease.
Return value
Number of octaves for the Perlin noise texture generation. The minimum value is 1, the maximum value is 16. The higher the value is, the more details the noise texture has.Image getImage ( ) #
Returns the noise texture image.Return value
Noise texture image.void setImageSize ( int size ) #
Sets the size of the noise texture in pixels.Arguments
- int size - Size of the noise texture in pixels.
int getImageSize ( ) #
Returns the size of the noise texture in pixels.Return value
Size of the noise texture in pixels.void setNoiseScale ( float scale ) #
Sets the scale of the noise texture.Notice
It is not recommended to change this parameter in run-time as the noise texture will be regenerated and the performance will decrease.
Arguments
- float scale - Scale of the noise texture. The minimum value is 0, the maximum value is 1.
float getNoiseScale ( ) #
Returns the scale of the noise texture.Return value
Scale of the noise texture. The minimum value is 0, the maximum value is 1.void setOffset ( vec3 offset ) #
Sets the sampling offset that will be used for pixel sampling from the noise texture.Notice
This parameter can be used to animate a force field in run-time.
Arguments
- vec3 offset - Sampling offset along the X, Y and Z axes.
vec3 getOffset ( ) #
Returns the sampling offset that is used for pixel sampling from the noise texture.Notice
This parameter can be used to animate a force field in run-time.
Return value
Sampling offset along the X, Y and Z axes.void setSize ( vec3 size ) #
Sets the size for the physical noise node.Arguments
- vec3 size - Size of the physical noise box in units. If a negative value is provided, 0 will be used instead.
vec3 getSize ( ) #
Returns the current size of the physical noise node.Return value
Size of the physical noise box in units.void setStep ( vec3 step ) #
Sets the sampling step that is used for pixel sampling from the noise texture.Notice
This parameter can be used to animate a force field in run-time.
Arguments
- vec3 step - Sampling step size along the X, Y and Z axes.
vec3 getStep ( ) #
Returns the sampling step that is used for pixel sampling from the noise texture.Notice
This parameter can be used to animate a force field in run-time.
Return value
Sampling step size along the X, Y and Z axes.void setThreshold ( vec3 threshold ) #
Sets a threshold distance set for the physical noise node. The threshold determines the distance of gradual change from zero to full force value. This values are relative to the size of the physical noise box. It means that the threshold values should be less than the size of the physical noise box.
Arguments
- vec3 threshold - Threshold distance along the X, Y and Z axes.
vec3 getThreshold ( ) #
Returns the threshold distance set for the physical noise node. The threshold determines the distance of gradual change from zero to full force value. This values are relative to the size of the physical noise box. It means that the threshold values should be less than the size of the physical noise box.Return value
Threshold distance along the X, Y and Z axes.static int type ( ) #
Returns the type of the node.Return value
PhysicalNoise type identifier.Last update:
