Suppose, I have defined a model view matrix as follows:

|1 0 0.0 -0.5cos(theta) 0|

|0.0 1.0 -0.5cos(alpha) 0|

|0.0 0.0 1.0 0|

|0.0 0.0 0.0 1.0|

where theta and alpha are some angles less that 90 degree.

What transformation actually this matrix does? Is it about some foreshortening along x and y direction?

Any clarification will be highly appreciated.
