Rotation with PVRTMat4::RotaionX


#1

Hi,


I had a problem in rotaion of square vertex array that consists of 2 triangles.


When I rotate the square with some degrees, the square shape is changed.

I think the reshape is caused by the display aspect ration. I use AM3517 EVM whose

display aspect ratio is not 1.

I'd like to rotate the square without reshape.

Does anyone show me some advice?
