How is the loop subprogram used in animation?
The loop subprogram allows iteration in Animation Nodes. Iteration is the act of executing a group of the nodes multiple times, each time is often called an Iteration. The Number Of Iterations ( Iterations for short) is the number of times the loop will execute.
What is the output of the loop node?
The Loop Input node returns the index of the current iteration, the number of iterations, the parameters—if available, and the outputs of the iterators—if available. The values of the parameters are equal to their default value if they are not exposed as inputs.
How to calculate the number of iterations in a loop?
The Number Of Iterations ( Iterations for short) is the number of times the loop will execute. Each iteration has an integer associated with it called an Index, this index is 0 for the first iteration, 1 for the second, 2 for the third and so on to the last iteration, which has an index n-1 where n is the number of iterations.
Which is the output of the iterator at first iteration?
At the first iteration, the output of the iterator will be the first object, thus the first object gets shaded smooth, at the second iteration, the output of the iterator will be the second object, thus the second object gets shaded smooth, and so on.
What kind of data does an animation node hold?
Animation Nodes have a special data type called Generic. This type can hold any other data type including lists as well as other generic data. This type is particularly useful in storing lists of lists. For instance, one could construct a generic list A composed of multiple float lists, in this case, the generic type holds lists.
Why are black sockets not allowed in animation nodes?
For instance, a blue socket represents a 3D Vector data type and a black socket represents an Object data type. If one attempts to connect two node sockets, unless they have the same data type or the origin type can be implicitly converted to the target type, Animation Nodes won’t allow the connection.
How does a vectorized node work in animation?
Some nodes in Animation Nodes are said to be “vectorized”. Vectorization is the ability of the node to operate on lists just as it can operate on individual elements. A vectorized node has vectorized sockets, such sockets change from list types to their element type and vise versa based on your input.
