i am makin a big picture using small triangles and then texture mapping the picture on the triangles by specifying texture coordinates for each coordinate of each triangle…
(i am using 1200X1200 small continous triangles to make a big picture)
i am also providing facility to rotate in any direction…
problem occurs when i try to rotate the picture because for each rotation all the triangles are drwan again for new set of values and texture mapping is performed again too
this takes whole lot of processing which makes the output very slow.
is there any way this issue can be handled and my program works little more smoothly???
