Author	Topic: try this switchin distance calculation
mposis Pilot	posted 04-22- 07:45 AM I got this calculation using an eye doctor's eyechart. If you have 20/20 vision it says you should be able to see a 0.4 inch object at a distance of 20 feet. Here is the formula: distance(feet) = object size(feet)x 20 / .033333 switchin = distance x distance See if this works. IP: Logged

Sv Pilot	posted 04-22- 10:42 PM However, just because a LOD switches in does not mean it is visible in SDOE. If it is a smaller part it may be less than 1 pixel in size, this would still be invisible. I am really considering adding over-sized far distance LODS to my WWI planes so you can at least see a speck sooner... -Sv IP: Logged

mposis Pilot	posted 04-24- 07:50 AM After some testing I found out this is not going to work well in all cases because when you zoom in on an object, SDOE actually moves you closer to it instead of just enlarging the image. I think dividing the calculated switchin distance by 2 works well. IP: Logged
Michael Harrison General	posted 04-24- 08:01 AM No FS doesn't actually move you closer when you zoom in. It does move the "apparent" distance closer so that higher level LOD's will switch in and you can see more detail. Objects between you and the plane you're looking at will continue to be in the way though. IP: Logged
mposis Pilot	posted 04-24- 08:48 AM MH, Thanks, can you tell me how you calculate the apparent distance in relation to zoom? Right now I am doing this by trial and error. [This message has been edited by mposis (edited 04-24-2000).] IP: Logged
