Py5Graphics.rotate()

Rotates the amount specified by the angle parameter.

Description

Rotates the amount specified by the angle parameter. Angles must be specified in radians (values from 0 to TWO_PI), or they can be converted from degrees to radians with the radians() function.

The coordinates are always rotated around their relative position to the origin. Positive numbers rotate objects in a clockwise direction and negative numbers rotate in the couterclockwise direction. Transformations apply to everything that happens afterward, and subsequent calls to the function compound the effect. For example, calling rotate(PI/2.0) once and then calling rotate(PI/2.0) a second time is the same as a single rotate(PI). All tranformations are reset when draw() begins again.

Technically, rotate() multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by Py5Graphics.push_matrix() and Py5Graphics.pop_matrix().

This method is the same as rotate() but linked to a Py5Graphics object. To see example code for how it can be used, see rotate().

Underlying Java method: PGraphics.rotate

Syntax

rotate(angle: float, /) -> None
rotate(angle: float, x: float, y: float, z: float, /) -> None

Parameters

  • angle: float - angle of rotation specified in radians

  • x: float - x-coordinate of vector to rotate around

  • y: float - y-coordinate of vector to rotate around

  • z: float - z-coordinate of vector to rotate around
