Author Project too slow
J_Zanetti

2004-01-26, 3:31 pm

Hello everyone,
I'm makin a project on vrml, it is ment to become very big with a lot of
object on it.
I did the 25% and it already starts to get very slow and very unpleasent to
navigate in. Im not an expert user of vrml, i use it since few months,
someone can help me finding the way to make this world less "heavy" for the
rendering processes? Thank you so much

Hi,

try to optimize it, for this use the 30 day trial of Chisel or
Webchisel. This programm will optimize your world without modifing the
mesh. For more infos about it check:

Hello

In first - check how many light you added.
If light are mor than eight , browser will
work slow
Second - use LOD, set visibilityRange (in NavigationInfo)
for value 5-10, use polygon optymizer.

Maybe it help

regards

Marcin

maybe you simply have "too much polygons problem". It happens when you
modeling things to the details, and especialy if you have too much round
objects. If so, solution is to change geometry.

For complex objects is much better to use textures for details.

Chisel can only decrease loading time.

If you have too much polygons for your graphicscard (beside of too much
lights), there are mesh reducers, but usually, there are rare, very slow
or very expensive.

The following compares the result of a heavy mesh reduce of the mesh reducer
in the SGI IRIX (UNIX) version of cosmoplayer with the export
from a low polygon modeller:

http://www.csv.ica.uni-stuttgart.de...l_optimize3.png

To hide ugly egdes, use normals or the creaseAngle field:

http://www.csv.ica.uni-stuttgart.de...tag/crease2.png
http://www.csv.ica.uni-stuttgart.de...tag/crease3.png

To show small structures, use textures instead of big meshes.

One alternative method of mesh reducion is to read/convert the 3D Modell
into a NURBS-only 3D modeller that gives you controll over the amount of
meshes written to the VRML file.
AFAIK, rhino 3D is such a NURBS 3D modeller.
