Gonna start 2d rotation image
Might continue to uncompressed movie rotations
Anyone already done this?

Thanks caballero :thumbsup:
First easy with rotate objects,lines
If i am restricted by 1024*768 ,showing 1024*1024 or bigger
C Break out of loop?much branch misprediction ?
So i want to try
Pixelshader inverse coding
So loop only 1024*768
I am trying to make a 8:24 fixed point solution on x, y together is used as pointer to where bmp2 new pixel appears
Kinda scanning from middle of bitmap bmp1 outwards
Got problem with suddenly result switch to negative- values, signbit probably doesnt work correctly when shift 8:24 fixed point using shift 24
Deltax =int (cos (alpha) *2^24) and deltay=int (sin (alpha)*2^24)
I take a break from this
One idea want to try is rotate rle encoded bitmap = mean of all lengths * faster rotation
