Name | ### scale()
Examples |
    rect(30, 20, 50, 50);
    scale(0.5);
    rect(30, 20, 50, 50);
    rect(30, 20, 50, 50);
    scale(0.5, 1.3);
    rect(30, 20, 50, 50);
    // Scaling in 3D requires P3D
    // or OPENGL as a parameter to size()
    size(100, 100, P3D);
    fill(255, 102);
    translate(width/2+12, height/2);
    box(20, 20, 20);
    scale(2.5, 2.5, 2.5);
    box(20, 20, 20);
Description | Increases or decreases the size of a shape by expanding and contracting vertices. Objects always scale from their relative origin to the coordinate system. Scale values are specified as decimal percentages. For example, the function call scale(2.0) increases the dimension of a shape by 200%. Transformations apply to everything that happens after and subsequent calls to the function multiply the effect. For example, calling scale(2.0) and then scale(1.5) is the same as scale(3.0). If scale() is called within draw(), the transformation is reset when the loop begins again. Using this fuction with the z parameter requires passing P3D or OPENGL into the size() parameter as shown in the example above. This function can be further controlled by pushMatrix() and popMatrix().
Syntax |
    scale(size);
    scale(x, y);
    scale(x, y, z);
Parameters |
size | float: percentage to scale the object
x | float: percentage to scale the object in the x-axis
y | float: percentage to scale the object in the y-axis
z | float: percentage to scale the object in the z-axis
Returns | None
Usage | Web & Application
