# Visibility Ranges (HLOD)
|
||||
|
||||
This demo showcases how to set up a hierarchical LOD system using visibility ranges.
|
||||
|
||||
This can improve performance significantly in 3D scenes by reducing the number of
|
||||
draw calls and polygons that have to be drawn every frame.
|
||||
|
||||
Use WASD or arrow keys to move, and use the mouse to look around. Press
|
||||
<kbd>L</kbd> to toggle the use of visibility ranges. Press <kbd>F</kbd> to
|
||||
toggle the fade mode between *transparency* (the default in this demo) and
|
||||
*hysteresis* (which is slightly faster, but results in more jarring
|
||||
transitions).
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Performance is expected to decrease significantly after disabling visibility ranges,
|
||||
> as all trees will be drawn with full detail regardless of distance.
|
||||
|
||||
Language: GDScript
|
||||
|
||||
Renderer: Forward Plus
|
||||
|
||||
## How does it work?
|
||||
|
||||
There are 2 goals when using visibility ranges to improve performance:
|
||||
|
||||
- Reduce the number of polygons that need to be drawn.
|
||||
- Reduce the number of draw calls, while also preserving culling opportunities when up close.
|
||||
|
||||
To achieve this, the demo contains four levels of LOD for each cluster of 16 trees.
|
||||
These are the levels displayed from closest to furthest away:
|
||||
|
||||
- Individual tree, with high geometric detail.
|
||||
- Individual tree, with low geometric detail.
|
||||
- Tree cluster, with high geoemtric detail.
|
||||
- Tree cluster, with low geometric detail.
|
||||
|
||||
When the distance between the camera and the tree's origin is greater than 20
|
||||
units, the high-detail tree blends into a low-detail tree (transition period
|
||||
lasts 5 units).
|
||||
|
||||
When the distance between the camera and the tree's origin is greater than 150
|
||||
units, all low-detail trees in the cluster are hidden, and the trees blend into
|
||||
a high-detail tree cluster. This transition period lasts for a longer distance
|
||||
(50 units) as the visual difference between these LOD levels is greater.
|
||||
|
||||
When the distance between the camera and the cluster's origin is greater than
|
||||
450 units, the high-detail tree cluster blends into a low-detail tree cluster
|
||||
(also with a transition period of 50 units).
|
||||
|
||||
When the distance between the camera and the cluster's origin is greater than
|
||||
1,900 units, the low-detail tree cluster fades away with a transition period of
|
||||
100 units. At this distance, the fog present in the scene makes this transition
|
||||
harder to notice.
|
||||
|
||||
There are several ways to further improve this LOD system:
|
||||
|
||||
- Use MultiMeshInstance3D to draw clusters of geometry in a single draw call.
|
||||
However, individual meshes will not benefit from frustum or occlusion culling
|
||||
(only the entire cluster is culled at once). Therefore, this must be done
|
||||
carefully to balance the number of draw calls with culling efficiency.
|
||||
- Use impostor sprites in the distance. These can be drawn with Sprite3D, or
|
||||
using MeshInstance3D + QuadMesh with a StandardMaterial3D that has
|
||||
billboarding enabled.
