My goal was to make a simple scene that could be mistaken for a real photograph of an apple. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The apple is simply a torus (or two toruses, one for the surface and another for the inside). The part that has been cut out is a height field based on a image I draw with a Paint program and prosessed with Image Composer. The texture of the apple is a three-layered texture with varying levels of bumps on them. One layer has very small bumps to give a rough appearence. One layer has bigger bumps to give a uneven appearence. The bottom layer is a simple specular texture to give the basic light reflection. Each layer uses the same hand drawn image map for color. For the droplets of water I wrote a small C program that places the droplets (i.e. spheres) on the surface of the torus. There are all together 2500 droplets, though roughly half of them are inside the apple and thus not visible. For the added realism I used Povray's spot area light, antialiasing and focal blur. I payed a big price for that: The rendering took so much time that I had no possibility to do it more than once. I'm not happy with the droplets' texture, the apple's image map of the bite's shape but I could correct them since there was no time to render the scene again. The scene has two lights: the main spot area light in the upper left direction and another dim point light at camera location. I've noticed that placing a dim light at camera location and using no ambient parameter gives a more pleasent ambient lighting that using the flat ambient parameter.
