Shear

Post by Shell1850 »

I am looking at IRdMatrixfDisp Interface. What do they mean by Shear?

Here's a pretty good example Shell1850:

http://cs.fit.edu/~wds/classes/cse5255/ ... shear.html"

In a sense, it's a form of non-uniform scaling.
If you scale a cube Uniformly, for example, then you end up with a larger cube.
But if you Shear a cube, say, along the z-axis, then you end up with a larger cube that is stretched
in the x and y axes.

I believe that is a correct statement. Please correct me if I am wrong.

Isn't more like Skew?

If you expand an object's Matrix and change to the EXP aspect you will see:

Is there a difference between shear and skew?
