Level of Detail (LOD) in
Babylon.js is a technique to optimize rendering performance in large-scale scenes or assets. It involves displaying different levels of mesh complexity based on the camera’s distance from an object, reducing GPU workload and improving frame rates.
In Babylon.js, LOD can be implemented using the
addLODLevel method on meshes. This method takes two parameters: the distance from the camera at which the
LOD change occurs, and the simplified mesh to display at that distance.
Multiple LOD levels can be added for varying distances.
For example :
let originalMesh = new BABYLON.Mesh("original", scene);
let lowPolyMesh = new BABYLON.Mesh("lowPoly", scene);
originalMesh.addLODLevel(50, lowPolyMesh);?
This code sets up a LOD system where the low-poly version of the mesh will be displayed when the camera is
50 units away or more from the original mesh.
Using LOD in
Babylon.js helps maintain smooth performance in complex scenes by reducing the number of polygons rendered as objects become less visible due to distance, ultimately enhancing user experience.
