Hide at a distance from the camera - works but slooooowwww

alexandre sk

Hello again.

I was playing with the ruby and make a little plug in to hide everything away from the camera.

Like this:

It work perfectly! but slow like a turtle! this scene above take about 20 seconds

Here is the script:


model=Sketchup.active_model
eye=model.active_view.camera.eye
selection = Sketchup.active_model.selection
selection.each { |entity|
	distance=eye.distance(entity.bounds.center)
	if distance > 20000
		entity.hidden = true
	end
}

I think that calculate the center of all items is very hard work. Maybe you guys have a way that don't make the cpu calculate so hard. Or maybe what is taking time is to calculate the distance, then teh ideia is bad after all.

You could also adjust the fog settings.

well the idea is to work with large models, and don't have to manually hide objects to give more frame rate. I thinks fog don't help with less entities to display.

Fog generally tends to slow down the framerate.
