optimizing the loading of .wrl files
Hi
I'm trying to program an enviorment that supports adding multiple instances of a .wrl image ( around 100-150 , and dynamically, during the run of the program ). The problem is that it takes a very long time and disrupts the flow of the program adding for example 50 such objects using the "node3d.add(nameOfWlr)" takes about 5 seconds - it just seems a bit wasteful, since it is always the same .wrl file, and each time it loads it anew from the file into vizard. Is there any way to optimize this? thanks dan |

The most optimal change would be to clone the existing model. However, changing the appearance of one object will affect all its clones. If you want to make unique appearance changes to each model, then the second best thing is to make a copy of the existing model. Here is sample code that will add 50 objects of the same file using the clone technique:
Code:
for x in range(50): model = viz.add('model.wrl',cache=viz.CACHE_CLONE) Code:
for x in range(50): model = viz.add('model.wrl',cache=viz.CACHE_COPY) |
