Made by Evan Wallace This demo requires a decent graphics card and up-to-date drivers. If you can't run the demo, you can still see it on YouTube. Interactions: Draw on the water to make ripples Drag the background to rotate the camera Press SPACEBAR to pause and unpause Drag the sphere to move it around Press the L key to set the light direction Press the G key to toggle gravity Features: Raytraced reflections and refractions Analytic ambient occlusion Heightfield water simulation * Soft shadows Caustics (see this for details) ** * requires the OES_texture_float extension** requires the OES_standard_derivatives extension Tile texture from zooboing on Flickr.

Unsorted. Environment Maps. News. Random space filling tiling of the plane. Written by Paul Bourke July 2011 Initial concept and inspiration by John Shier.

Additional examples by John Shier: statistical_geometry_examples.pdf The following illustrates a technique of iteratively tiling the plane with non-overlapping shapes where, on each iteration, the position is determined randomly and the area is some decreasing function. Note that the shapes, when circles, are not added as "Soddy" circles as in Apollonian [3] space filling fractals, nor do they even need to touch at a single point of another shape [4]. If the area of the initial shape is A0 and the decreasing function at iteration i is g(i) then the area at each iteration is : A0, A0 g(1), A0 g(2), .... The total area at the n'th iteration is given by the following, and it is this area that needs to match the bounded area of the plane being filled.

There are many possible choices for g(i), but choices that are space filling are possibly very few [1]. The total area for the infinite series is then given by : Institut für Computergraphik und Algorithmen - Arbeitsgruppe für Computergraphik.

Introduction Traditionally, 3D objects and virtual worlds are defined by lists of geometric primitives: cubes and spheres in a CSG tree, NURBS patches, a set of implicit functions, a soup of triangles, or just a cloud of points.

The term 'generative modeling' describes a paradigm change in shape description, the generalization from objects to operations: A shape is described by a sequence of processing steps, rather than just the end result of applying operations. Shape design becomes rule design. This approach is very general and it can be applied to any shape representation that provides a set of generating functions, the 'elementary shape operators'. Its effectiveness has been demonstrated, e.g., in the field of procedural mesh generation, with Euler operators as complete and closed set of generating functions for meshes, operating on the halfedge level.

The 'generative modeling language' GML is a concrete implementation of the generative approach. Mailing List.
