Hello,I have a problem for 2D rotation.When I rotate my sprite,there are holes on the destination image(I think that it's the rounding function).Somebody told me that I have to rotate the dest. image in the oposit side,then,I have to give the color of the SRC's found pixel.But That doesn't work?!<br>
Sorry for my bad explanation(I'm not very good in english).I can send the source(C),for more understanding.<br>
Please help me!<br>
Thanx,<br>
Bye,

Hi MIG31,<br>
You need to draw the pixels on the screen from top to bottom and from left to right. Then you've to re-calculate (back-calculate) which Texel's (Pixel in Texture) color should be set there.<br>
What yo've done (I think) is: You've draw the Sprite from Sprite to Screen, but you have to it the other way: through screen, onto Sprite, get the color and set it on screen.<br>
To do this you really have to do the opposite transfiguration. Enlarge the coordinates if you want to have a smaller sprite and turn the coordinates left if you want to have a right-rotated image of the sprite.<br>
<br>
Hope I helped you - if not, let me know<br>
