I'm experimenting with OpenScenegraph for a new project, and I've build
a simple application that opens 2 viewer windows, and places 3 teapots
in them (using the teapot object from the osgteapot example),
translating them into different positions. My resulting scene graph
(saved as an osg) looks like this:
Group {
UniqueID Group_0
nodeMask 0xffffffff
cullingActive TRUE
num_children 3
Group {
UniqueID Group_1
nodeMask 0xffffffff
cullingActive TRUE
StateSet {
UniqueID StateSet_2
DataVariance STATIC
rendering_hint DEFAULT_BIN
renderBinMode USE
binNumber 50
binName RenderBin
}
num_children 1
MatrixTransform {
nodeMask 0xffffffff
cullingActive TRUE
referenceFrame RELATIVE
Matrix {
1 0 0 0
0 1 0 0
0 0 1 0
0 -50 0 1
}
num_children 1
Geode {
UniqueID Geode_3
nodeMask 0xffffffff
cullingActive TRUE
StateSet {
UniqueID StateSet_4
DataVariance STATIC
rendering_hint DEFAULT_BIN
renderBinMode INHERIT
Material {
ColorMode OFF
ambientColor 0.2 0.2 0.2 1
diffuseColor 0.8 0.8 0.8 1
specularColor 0 0 0 1
emissionColor FRONT 0 1 0 1
emissionColor BACK 1 0 0 1
shininess 0
}
LightModel {
ambientIntensity 0.2 0.2 0.2 1
colorControl SINGLE_COLOR
localViewer FALSE
twoSided TRUE
}
}
num_drawables 1
}
}
}
Group {
UniqueID Group_5
nodeMask 0xffffffff
cullingActive TRUE
Use StateSet_2
num_children 1
MatrixTransform {
nodeMask 0xffffffff
cullingActive TRUE
referenceFrame RELATIVE
Matrix {
1 0 0 0
0 1 0 0
0 0 1 0
-10 -50 0 1
}
num_children 1
Use Geode_3
}
}
Group {
UniqueID Group_6
nodeMask 0xffffffff
cullingActive TRUE
Use StateSet_2
num_children 1
MatrixTransform {
nodeMask 0xffffffff
cullingActive TRUE
referenceFrame RELATIVE
Matrix {
1 0 0 0
0 1 0 0
0 0 1 0
10 -50 0 1
}
num_children 1
Use Geode_3
}
}
}
Pretty basic.. However, I'm only getting about 60-70fps (in each of my 2
viewers). I've already set the vsync=false in my Stateset for the
viewer (if I run with _nothing_ in my Scene Graph I get over 1000fps).
Is this typical performance? I really expected to still be getting
100+fps easy with such trivial geometry.
