Day 42

Today I continued working on the same old problem.

Mr Ron dropped by today and provided me with lots of assistance. He told me that the way of moving a single point to trigger the secondary fracture really didn't work out the way it is supposed to. He asked me how I wanted the trigger for the secondary fracture to work. I told him that I would prefer the original way of using the particles to drive the trigger for the secondary fracture, then use copy stamping to copy each piece onto each particle. He helped me start,

Firstly, He went into the lowest level of the foreach, where the center point was created. He deleted everything below the group node that grouped the center point of the geometry piece.





















After doing that, Mr Ron went up to the geometry level and realised that there are overlapping pieces on top of each other. To fix that problem, he went back into the foreach node, and under the voronoi fracture node, he set the piece prefix to:





















That creates the fracture pieces with the new naming convention of newPiece

And we got to change the foreach node after the voronoi fracture node to newP* as we want to add the points onto the new fracture piece not the old one.

Then on the geometry level, a delete node is used to delete all the groups except the newPiece group.

On the other side, a delete node is used to delete everything except the center points created by the foreach node.





















Then it is connected to a popnetwork.

Inside the popnetwork is more or less the same as the previous. Except that, the particles are moving but they are also not birthing at the same time. Hence, it proved to be a challenge. But Mr Ron helped me fix it by using a position node, to track the point position data.























After using that, the particles moved according to how it was supposed to move before.

I then proceeded on to use a force and a bounding box to animate them breaking apart.

I then did a rop.

I will post further updates on Monday.
