To view the inputs required for the trimmer and prism meshers, do the following:
The trimmer produces the most optimal cells when the trimming surface contains elements of the same size as those being trimmed. For this reason, the same surface remesher values as used in the first part of the tutorial will be used for the global trimmer settings in this case. A summary of all the reference values is provided below:
The Maximum Cell Size node controls the maximum size of the cells that will be allowed away from the surface, that is, in the core. In this instance it has been left at the default value (10000% of the Base Size) meaning that the size is relatively unconstrained and can grow many times more than the surface size if required. If smaller cells were required in the core then this value should be reduced.
The Template Growth Rate option controls the extent to which the cells are refined. The Default Growth Rate, set to Fast by default, controls the transition rate in the interior volume mesh (away from the surface). Setting it to fast means it will transition as quick as possible from one layer to the next, using a minimum of one cell for each transition layer. The Surface Growth Rate, set to None by default, controls the number of layers of cells at the surface. Setting it to none means that the default growth rate value will determine the number of cells to grow at the surface. If you wanted additional refined cells then you could choose one of the other options such as medium or slow, which would introduce at least 2 or 4 refined levels of cells respectively.
