Unigine::ParticlesFieldSpacer Class

Header: #include <UnigineParticlesFields.h>
Inherits from: ParticlesField

This class represents a spacer for particles generated by Particle Systems. Spacer — is a volumetric field that has no visual representation, but physically interacts with particle systems (other objects are not affected). This field is used to cut particles out from a certain volume (particles it comes in contact with), for example, to avoid rendering of rain inside a car. It can have a box, cylinder, capsule, sphere, or ellipse shape, size, and can be arbitrarily positioned or rotated to cover the necessary area.

Members


ParticlesFieldSpacer ( ) #

Constructor. Creates a new Particles Field Spacer with default parameters.

ParticlesFieldSpacer ( const Math::vec3 & size ) #

Constructor. Creates a new box-shaped Particles Field Spacer of the specified size.

Arguments

  • const Math::vec3 & size - Size of the Particles Field Spacer along the X, Y, and Z axes to be set, in units. In case the spacer has an ellipse shape, each component of the vector sets a radius along the corresponding axis.

static int type ( ) #

Returns the type of the Particles Field Spacer node.

Return value

ParticlesFieldSpacer type identifier.

void setShapeType ( ParticlesFieldSpacer::SHAPE_TYPE type ) #

Sets a new shape for the Particles Field Spacer.

Arguments

ParticlesFieldSpacer::SHAPE_TYPE getShapeType ( ) const#

Returns the current shape of the Particles Field Spacer.

Return value

Current shape type of the Particles Field Spacer. One of the SHAPE_TYPE* values.

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

Sets a new size for the Particles Field Spacer.

Arguments

  • const Math::vec3 & size - New size of the Particles Field Spacer along the X, Y, and Z axes to be set, in units. In case the spacer has an ellipse shape, each component of the vector sets a radius along the corresponding axis.

Math::vec3 getSize ( ) const#

Returns the size of the Particles Field Spacer

Return value

Current size of the Particles Field Spacer along the X, Y, and Z axes, in units. In case the spacer has an ellipse shape, each component of the vector sets a radius along the corresponding axis.

void setRadius ( float radius ) #

Sets a new radius for the Particles Field Spacer.

Arguments

  • float radius - New radius to be set for the Particles Field Spacer, in units.

float getRadius ( ) const#

Returns the current radius of the Particles Field Spacer.

Return value

Current radius of the Particles Field Spacer, in units.

void setHeight ( float height ) #

Sets a new height value for the Particles Field Spacer.

Arguments

  • float height - New height value to be set for the Particles Field Spacer, in units.

float getHeight ( ) const#

Returns the current height of the Particles Field Spacer.

Return value

Current height of the Particles Field Spacer, in units.
