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

Constructor. Creates a physical wind node of the specified size.

Arguments

• const Math::vec3 & size - Wind box size in units.

void setAngularDamping ( float damping ) #

Sets a value indicating how much the angular velocity of the objects decreases when they get inside the wind node.

Arguments

• float damping - Angular damping value. If a negative value is provided, 0 will be used instead.

float getAngularDamping ( ) #

Returns the current value indicating how much the angular velocity of the objects decreases when they get inside the physical wind node.

Return value

Angular damping value.

void setLinearDamping ( float damping ) #

Sets a value indicating how much the linear velocity of the objects decreases when they get inside the wind node.

Arguments

• float damping - Linear damping value. If a negative value is provided, 0 will be used instead.

float getLinearDamping ( ) #

Returns the current value indicating how much the linear velocity of the objects decreases when they get inside the wind node.

Return value

Linear damping value.

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

Sets the size of the physical wind node.

Arguments

• const Math::vec3 & size - Wind box size in units.

Math::vec3 getSize ( ) #

Returns the current size of the physical wind node.

Return value

Wind box size in units.

void setThreshold ( const Math::vec3 & threshold ) #

Sets the threshold distance values along the coordinates axes relative to the wind node size (that is, inside of it). It determines the area of gradual change from zero to full wind velocity.

The threshold distance values form an invisible box, inside which the wind blows with full velocity:

Arguments

• const Math::vec3 & threshold - Threshold distance in units.

Math::vec3 getThreshold ( ) #

Returns the current threshold distance values along the coordinates axes relative to the wind node size (that is, inside of it). It determines the area of gradual change from zero to full wind velocity. See also setThreshold().

Return value

Threshold distance in units.

void setVelocity ( const Math::vec3 & velocity ) #

Sets the velocity of the physical wind flow along the axes.

Arguments

• const Math::vec3 & velocity - Velocity in units per second.

Math::vec3 getVelocity ( ) #

Returns the current velocity of the physical wind flow along the axes.

Return value

Velocity in units per second.

static int type ( ) #

Returns the type of the node.

Return value

Physical type identifier.
