Question

我一直在进行一场血清巨大的模拟,这意味着它成为动物和动物的必备条件。

I found a good working script but when the simulation got bigger I found it had a problem... The more you zoom in, the smaller the steps became and the further you zoom out, the bigger.

This is a problem because I need the steps to be equal no matter what zoom level you are.

现在使用的文字Im是:

var total = 75,
    delta = e.detail ? e.detail * -120 : e.wheelDelta; //e is mouse event

this.zoomValue += (delta > 0) ? 1 : -1;

this.zoomRatio = 1 + (this.zoomValue / total) * 2;
e.preventDefault();

我在后来用苏马洛计算各种物体的位置。

谁知道如何以更好的方式去干活?

Answer 1

The anwser is very simple actualy... yet I needed somebody to show me before I saw it myself.

解决办法是使其分数化,这样

this.zoomRatio = Math.exp(this.zoomValue);

如果trick,你可以做这样的事情。

this.zoomRatio = Math.exp(this.zoomValue / 10);

使其分小步发展。
