Description

Rotates around the x-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted from degrees to radians with the radians() function. Coordinates are always rotated around their relative position to the origin. Positive numbers rotate in a clockwise direction and negative numbers rotate in a counterclockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling rotate_x(PI/2) and then rotate_x(PI/2) is the same as rotate_x(PI). If rotate_x() is run within the draw(), the transformation is reset when the loop begins again. This function requires using P3D as a third parameter to size() as shown in the example.

Underlying Java method: rotateX
