View Full Version : Zooming using depth buffer

11-29-2010, 01:44 AM
Hi All,

We are trying to implement the zoom by mouse wheel using the depth buffer in perspective projection. It is already working but we cannot find a reasonable way to estimate a minimum thresold to dive inside the model. We currently multiply current Z by 0.9 otaining a slow down very useful when you are approaching a model small detail.

How can we estimate a *good* minimum thresold to dive in the model before getting a speed close to zero (like 0.000000001023123) ?
