Projection.scale

Syntax

scale(m: Number);

Parameters

m. Scale to be set.

Description

The scale method scales a coordinate system.

Example

To execute the example the HTML page must contain the MapChart component map (see Example of Creating the MapChart Component). Open a spherical map. Get model and view matrix:

// Get class object used to work with 3D projection
var projection = map.getGLControl().getProjection();
// Get model and view matrix
console.log("Model and view matrix: ");
console.log(projection.getModelMatrix().getData());

As a result the console displays model and view matrix:

Model and view matrix:

[1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, -1.089900016784668, 1]

Change coordinate system scale and get a new model and view matrix:

// Change scale
projection.scale(2);
// Get a new model and view matrix
console.log("Model and view matrix: ");
console.log(projection.getModelMatrix().getData());

As a result the console displays model and view matrix:

Model and view matrix:

[1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, -2.179800033569336, 2]
