Example

To execute this example, in the HEAD tag of HTML page specify links to the following JS and CSS files: PP.js, PP.GraphicBase.js. Create a new matrix:

// Create a matrix
matrix = new PP.Matrix4([
4.717621803283691, 0, 0, 0, 
0, 10.385396957397461, 0, 0,
0, 0, -1.0000020265579224, -1, 
0, 0, -0.002000001957640052, 0
]);
// Set orthographic projection
matrix.setPerspective(5, 3, 2, 3, 5, 10);
// Get matrix values
matrix.getData();
// -> [-1, 0, 0, 0, 0, 2, 0, 0, 0, 0, -0.4000000059604645, 0, 4, -5, -3, 1]

After executing the example an orthographic projection matrix is set.
