Alpine Trees: an Introduction to Terrain
turtleSpaces new terrain functionality provides some great opportunities for simple coding examples with few lines of Logo code, in this case less than 30.
First, we need to introduce the setterrain primitive. setterrain creates ‘terrain’ or a contiguous object of varying elevation.
The above is an example of the object created by setterrain. The setterrain primitive takes a number of parameters, and is a good opportunity to explain the different types of parameters used in turtleSpaces to students.
