<td>Specifies an amount to displace objects within the display window. The <b>x</b> parameter specifies left/right translation, the <b>y</b> parameter specifies up/down translation, and the <b>z</b> parameter specifies translations toward/away from the screen. <span class="warning">Using this function with the <b>z</b> parameter requires using the P3D or OPENGL parameter in combination with size as shown in the above example.</span> Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling <b>translate(50, 0)</b> and then <b>translate(20, 0)</b> is the same as <b>translate(70, 0)</b>. If <b>translate()</b> is called within <b>draw()</b>, the transformation is reset when the loop begins again. This function can be further controlled by the <b>pushMatrix()</b> and <b>popMatrix()</b>.</td>
