Particle position

Post by chriss0212 » 28 Jun 2018, 17:02

Is it possible to get the positions from particles to connect objects to them which are NOT part of the particle system?

Hi,

We do not provide nodes to read back particle positions.

6.01.00 will feature particle touch. The major limitation of this is that the collision detection will work only for spheres, independent of how the particles are drawn.

The particles are calculated in the GPU, and if the CPU wants to read the particle position back from the GPU this will cause a 2-3 frame delay, because the CPU is already sending commands for the next frame while the GPU is still busy drawing the current frame.

Attaching an object to a particle with the delay would look ugly. Particle touch also has a 2-3 frame delay, which is acceptable for interaction (actually, in interlace, this is a field delay).
