I have a special task and need some hints to optimize it.
1. bill board display
There is a background picture with a certain size (e.g. 240x32) and there is a text which should be displayed over that background picture with a certain amount of characters. Only 20 characters of the possible 120 characters should be displayed in that animation image.
The background should move in with a speed vb and the characters should move in with the speed vc. Positive speed means from right to left, negative speed means from left to right.
The background picture will be repeated as needed.
After it has displayed all it should loop.
2. above picture should be displayed on a cylinder !!!
That means only a portion of the above billboard can be displayed.
The curve of the cylinder will distort the sides in regards to the distance of the middle.
Any ideas what would do that all. Which commands to optimize that task?
