Field Detail

numParticles

int numParticles

The number of particles

positions

float[] positions

The positions of the particles.

 positions[particleIndex*STRIDE+0] = position.x;
 positions[particleIndex*STRIDE+1] = position.y;
 positions[particleIndex*STRIDE+2] = position.z;
 where 
 particleIndex = 0...numParticles-1
 STRIDE = 4 (usually)
 

candidatePositions

float[] candidatePositions

The candidate positions of the particles, which are used for the intermediate state of the computation. Using the same layout as the positions

velocities

float[] velocities

The velocities of the particles. Using the same layout as the positions

accelerations

float[] accelerations

The accelerations of the particles. Using the same layout as the positions

invMasses

float[] invMasses

Stores for each particle its inverse mass

numConstraints

int numConstraints

The number of constraints.

constraints

int[] constraints

The constraints for the particles. That is, the indices of particles that should not move due to the simulation.

 constraints[index] = indexOfConstrainedParticle
 where
 index = 0...numConstraints-1
 

constraintPositions

float[] constraintPositions

The positions of the constraints.

 positions[constraintIndex*STRIDE+0] = position.x;
 positions[constraintIndex*STRIDE+1] = position.y;
 positions[constraintIndex*STRIDE+2] = position.z;
 where 
 constraintIndex = 0...numConstraints-1
 STRIDE = 4 (usually)
