Unigine::JointParticles Class

Header: #include <UniginePhysics.h>
Inherits from: Joint

This class is used to pin cloth body or rope body to rigid bodies, ragdolls or dummy bodies.

Example#

The following code illustrates connection of a rope body (rope) and a dummy body (dummy) using a particles joint. The anchor is placed at the position of a dummy body.

Source code (C++)
include <UniginePhysics.h>

/* .. */

//the anchor point is placed at the position of a dummy body, pinning area size is (0.5f, 0.5f, 1.5f)
JointParticlesPtr joint = JointParticles::create(dummy, rope, dummy->getObject()->getPosition(), Vec3(0.5f, 0.5f, 1.5f)));

// setting pinning threshold
joint->setThreshold(0.001f);

// setting number of iterations
joint->setNumIterations(4);

JointParticles Class

Members


static JointParticlesPtr create ( ) #

Constructor. Creates a particle joint with an anchor at the origin of the world coordinates.

static JointParticlesPtr create ( const Ptr<Body> & body0, const Ptr<Body> & body1 ) #

Constructor. Creates a particle joint connecting two given bodies. An anchor is placed in the center of the body to which the cloth or rope is pinned.

Arguments

static JointParticlesPtr create ( const Ptr<Body> & body0, const Ptr<Body> & body1, const Math::Vec3 & anchor, const Math::vec3 & size ) #

Constructor. Creates a particles joint connecting two given bodies with specified pinning area size and an anchor placed at specified coordinates.

Arguments

  • const Ptr<Body> & body0 - First body to be connected with the joint. It can be one of the following:
  • const Ptr<Body> & body1 - Second body to be connected with the joint. It can be one of the following:
  • const Math::Vec3 & anchor - Anchor coordinates.
  • const Math::vec3 & size - Area for pinning vertices of cloth or rope body to another body.

int getNumParticles ( ) #

Returns the total number of pinned particles of the cloth or rope body.

Return value

The number of pinned particles.

float getParticleMass ( int num ) #

Returns the mass of the pinned particle of the cloth or rope body.

Arguments

  • int num - Particle number.

Return value

Particle mass.

Math::vec3 getParticlePosition ( int num ) #

Returns the position of the pinned particle of the cloth or rope body.

Arguments

  • int num - Particle number.

Return value

Particle position.

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

Updates a size of the area for pinning vertices of cloth or rope body to another body.

Arguments

  • const Math::vec3 & size - Size of the area to be pinned.

Math::vec3 getSize ( ) #

Returns the current size of the area of pinned vertices of cloth or rope body to another body.

Return value

Size of the pinned area.

void setThreshold ( float threshold ) #

Updates a threshold that determines the distance for pinning vertices of cloth or rope body to another body. If vertices are closer than the threshold, they are pinned together; otherwise, particles stay loose.

Arguments

  • float threshold - Threshold of pinning distance.

float getThreshold ( ) #

Returns the current threshold that determines the distance for pinning vertices of cloth or rope body to another body. If vertices are closer than the threshold, they are pinned together; otherwise, particles stay loose.

Return value

Threshold of pinning distance.

void clearParticles ( ) #

Unpins the cloth or rope body completely.
