Minimal Geo

Introduction​

This example demonstrates very simple minimal GLDF file implementation with no complexity.

Explanation​

The setup of the file is very straightforward. It contains a simple 3D geometry, light emitter, and light source in the general definitions section with a minimum amount of meta information.

It also references a basic L3D file in the file definitions. The screenshot below shows that the 3D file contains only one light-emitting object named LEO, which we will reference later in the Geomtry part of the product.xml file.

product.xml​

The following XML code references the single light-emitting object of the 3D file. The 3D file is referenced in line 15-16 and the LEO inside this 3D file in the Emitter in line 68.
