Unigine::FieldAnimation Class

Header: #include <UnigineFields.h>
Inherits from: Field

This class allows you to create and modify field animation objects.

  • A set of UnigineScript samples located in the <UnigineSDK>/data/samples/fields/ folder:
    • animation_00
    • animation_01

FieldAnimation Class

Members


static FieldAnimationPtr create ( const Math::vec3 & size ) #

Creates a new field animation node of the specified size:
  • If the field animation is of an ellipse shape, its radius values along the axes must be specified.
  • Otherwise, dimensions of the cube must be specified.

Arguments

  • const Math::vec3 & size - A size of the field animation along X, Y and Z axes in units.

void setAnimationScale ( float scale ) #

Sets the animation scale value indicating the scale for speed of vegetation swaying.

Arguments

  • float scale - The scale for speed of vegetation swaying value.

float getAnimationScale ( ) const#

Returns the animation scale value indicating the scale for speed of vegetation swaying.

Return value

The scale for speed of vegetation swaying value.

void setAttenuation ( float attenuation ) #

Sets an attenuation coefficient value for the Field Animation.

Arguments

  • float attenuation - An attenuation coefficient value. If a too small value is provided, 1E-6 will be used instead.

float getAttenuation ( ) const#

Returns the current attenuation coefficient for the Field Animation that indicates how much animation fades away starting from the center of the animation field to its edges:
  • By the minimum value of 0, no animation will be visible.
  • The higher the value, the more intensive animation will be at the edges of the animation field.

Return value

Current attenuation coefficient value.

void setEllipse ( bool ellipse ) #

Transforms a cube-shaped field animation into an ellipse-shaped one or vice versa.

Arguments

  • bool ellipse - true for the ellipse-shaped Field Animation, false for the cube-shaped one.

bool isEllipse ( ) const#

Returns a value indicating if the Field Animation is of an ellipse shape.

Return value

true if the Field Animation is of an ellipse shape; otherwise, false.

void setLeaf ( float leaf ) #

Sets a leaf animation coefficient value.

Arguments

  • float leaf - A new leaf coefficient value. If a negative value is provided, 0 will be used instead.

float getLeaf ( ) const#

Returns the current leaf animation coefficient value.

Return value

The leaf animation coefficient value.

void setSize ( const Math::vec3 & size ) #

Sets an animation field size.

Arguments

  • const Math::vec3 & size - A new animation field size along the X, Y and Z axes in units. If a negative value is provided, 0 will be used instead.

Math::vec3 getSize ( ) const#

Returns the animation field size:
  • If the field animation is of an ellipse shape, its radius values along the axes will be returned.
  • Otherwise, dimensions of the cube will be returned.

Return value

The current animation field size along the X, Y and Z axes in units.

void setStem ( float stem ) #

Sets a stem animation coefficient value.

Arguments

  • float stem - A new stem animation coefficient value. If a negative value is provided, 0 will be used instead.

float getStem ( ) const#

Returns the current stem animation coefficient value.

Return value

The stem animation coefficient value.

void setWind ( const Math::vec3 & wind ) #

Sets wind coefficients values that define wind direction inside the animation field.

Arguments

  • const Math::vec3 & wind - Wind coefficients values along the X, Y and Z directions.

Math::vec3 getWind ( ) const#

Returns the wind coefficients values that define wind direction inside the animation field.

Return value

Current wind coefficients values along the X, Y, and Z directions.

static int type ( ) #

Returns the type of the object.

Return value

FieldAnimation type identifier.
