How it works
Breeding plants using the breederBreeding creates new offspring plants from parents using random variation. About 150 of the over 200 parameters that make up a plant are numerical values. We realized early on that it might be fun to introduce random variation into these numerical parameters and see what happens. The result is a sort of pseudo-evolutionary process. In each breeding generation you can select the most interesting plant, then breed it further to produce strange, beautiful, or imaginative plants. The breeder isn't concerned much with botanical accuracy, but it produces some pretty amazing-looking plants. Breeding works by
Mutation: Each parameter in a breeding offspring is randomly selected from a normal (bell-shaped) distribution around the mean parent value (from one or two parents). The higher the mutation, the greater the standard deviation of the normal distribution, so the higher the variation.
Blending: The mean of the mutation distribution is either the parameter value from one parent, or a weighted mean from two parents. You can combine the two parents in any weighting combination. IMPORTANT: The plants in the breeder are NOT saved with the plant file and are lost when you leave the program. If you want to save a breeder plant, drag or copy it to the main window and save the plant file. Tasks: Breeding from one parent Breeding from two parents Taking a breeder plant out of the breeder Replacing breeder plants Randomizing breeder plants Deleting breeder generations Changing the age of breeder plants Changing the size of the breeder See also: Changing breeding options Dragging plants Cutting, copying, and pasting plants Undoing and redoing
