GeoImage Tutorial Introduction
GeoImage imports a list of pictures and corresponding labels.
It textures a picture on a rectangle while preserving aspect ratio
(the picture is called the GeoImage). The texturing takes place on both
sides of the rectangle so that the picture is seen from either side.
The sample animates the geoimage in 3-D, punctuates when the geoimage is in
the image plane with an audible tick, uses arrow keys and the space
bar to cycle through the pictures and corresponding labels, and renders
the original picture as a bitmap, the animate geoimage, and the label.
The key DirectAnimation points that are demonstrated include:
- aggregate events using orEvent
- creating a counter with application event data and the untilNotify method
- using number behaviors as indexes to arrays of behaviors
- newUninitbvr and init for looping transform and sound
- texturing images on rectangles while preserving aspect ratio
- 2-D/3-D interplay, via the relation of geoimage with picture
- using sound to punctuate instances in the animation
- rendering text into images
