Heightfield: Inhospitable
This is a heightfield render done in WinImages. I used the fractal generator to do the surface, enabled cliffing, and built a sand texture with ripples and dither. A heightfield is an image where the brightness of a pixel is treated as altitude, and the horizontal and vertical positions correspond to positions like measurements across a map of territory do. Software that creates heightfields — like WinImages — do so so they can enable you to easily create maps and other visual representations of terrain that detail altitude directly associated with position. These can be real (those would be heightmaps of various real places) or they can be artificial, of imaginary places (as are my examples here.) Once you have a heightfield, some software (again, like WinImages, though in this case WinImages is more a previewer than a serious landscape renderer) can take that greyscale image and using various tools and options, turn it into a more-or-less realistic 3D picture that, hopefully, either is useful or aesthetically pleasing. In the latter case, as here, it is my hope that my creations, which are imaginary rather than realistic in nature, provoke the viewer and their artistic sensibilities to some small degree.
