level of detail, rendering polygons

[dsdsdsdsd]

hello;

I understand that there exists the lod modifier and also hither/yon camera
properties;

asside from these are there any other ideas on controlling rendered polygons?

thanks

can you explain a littel bit more what you seek?

you can use the sds modifier to add polygones to a model, you can set the
visibility to front, back, both and none and it is possible to use
"removefromworld" and "addtoworld" if you want to take out complete models from
rendering....

cheers!

hondo3000, thanks for responding;

I am currently using a removefromworld/addtoworld manager;

one thing that would be very interesting is a way to not render anything that
is not in front of the camera;

any thoughts?

the shockwave3D engine renders only things that are infront of the camera. There is only the part renderred that is determined by the field of view, yon, and hither.

hondo3000, are you certain that the out-of-camera stuff is not being rendered;
I have a five storey building; when all 5 storeys are added to world the
character movement is very sluggish even though storeys 2-5 cannot be seen; but
if I removefromworld storeys 2-5 the animation runs smoothly;

NEW QUESTION : once the lod.level has been decreased to 60, is it not possible
to get the lod.level back to 100;

thanks

>are you certain that the out-of-camera stuff is not being rendered
yes! but don't mix up "modelsunderray" with the rendering.

I think you use a "modelsunderray" solution for collisiondetection. in this
case you should "removefromworld" all models that don't have to be checked for
collision and "addtoworld" them after the lines of code that handle the ray
collision.

check the "lifedocs" for more informations on optimizing the "modelsunderray"
stuff, you can set a list of models that have to be checked and you can
specifie a maximum distance. these stuff can help to make things faster.

to the new question:
i think changing the lod.level back to 100 should be no problem, are you sure
you set "lod.auto=false" ?
