END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

2D fractals can have a 3D look. Here is an image created with Image Traps and a image tiling plugin. The image is small (375 x 375) but since it is tiled, it looks OK. With Image Traps convolution filters can also be applied, in this case an emboss filter. This is not your ordinary emboss filter. If you use something like Photoshop to emboss you will get a gray-scale or mostly gray-scale image. The emboss filter I used (and wrote) gives color embossing. The orbit trap used is the Astroid function.
