Specifies an amount to displace objects within the display window. The
x parameter specifies left/right translation, the
y parameter specifies up/down translation.
Transformations are cumulative and apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, translating x by 50 and then translating x by 20 is the same as translating x by 70. All transformations are reset when
draw begins again.
Technically, translate multiplies the current transformation matrix by a translation matrix. This function can be further controlled by the push and pop.
