Hi,
I tried to create a dynamic heightField by attaching a heightField Shape
drawable into a Geode node, and then I called the dirtyDisplayList on each
frame. I noticed that the frame rate drop a lot when the HF is quite big ( 200
x 200 ). I did the same test by using a drawable of type geom and I get a
better perforamance.
My questions are the follow:
1- What is the best to create a dynamic heightField?
2- Is there any optimal way to update the heights of a given heightField
shape. I did this attempt osg::HeightField::getFloatArray()->dirty()
but it didn't update the heights.
3- What about the use of osg::Terrain/osg::TerrainTile to create a
dynamic heightField? Is it a better alternative in term of perforamce?
Thank you!
Cheers,
bilal
