چکیده

A procedural pattern generation process, called multi-scale “assemblage” is introduced. An assemblage is defined as a multi-scale composition of “multi-variate” statistical figures, that can be kernel functions for defining noiselike texture basis functions, or that can be patterns for defining structured procedural textures. This paper presents two main contributions: 1) a new procedural random point distribution function, that, unlike point jittering, allow us to take into account some spatial dependencies among figures and 2) a “multi-variate” approach that, instead of defining finite sets of constant figures, allows us to generate nearly infinite variations of figures on-the-fly. For both, we use a “statistical shape model”, which is a representation of shape variations. Thanks to a direct GPU implementation, assemblage textures can be used to generate new classes of procedural textures for real-time rendering by preserving all characteristics of usual procedural textures, namely: infinity, definition independency (provided the figures are also definition independent) and extreme compactness.

APST Antialiased Procedural Texturing Interface for OpenGL

The current implementation of OpenGL only supports standard 1-D and 2-D texture mapping. An interface is proposed to extend the OpenGL library, to support a simpli ed model of antialiased procedural solid texturing in OpenGL version 1.1. This extension to the OpenGL language does not modify the existing OpenGL standard. It is designed as a supplemental library that works with existing implement...

Chapter 6: Procedural Solid Texturing

Procedural solid texturing was introduced fourteen years ago, but has yet to find its way into consumer level graphics hardware for real-time operation. To this end, a new model is introduced that yields a parameterized function capable of synthesizing the most common procedural solid textures, specifically wood, marble, clouds and fire. This model is simple enough to be implemented in hardware...

Animation with Threshold Textures

We present a method for frame coherent texturing and hatching of 3D models with a discrete set of colors. Our technique is inspired by various artistic styles that use a limited set of colors to convey surface shape and texture. In previous research discrete color shading was produced by modifying smooth shading with a threshold function. We extend this approach and specify threshold values wit...

The Solid Map: Methods for Generating a 2-D Texture Map for Solid Texturing

The solid map provides a view-independent method for solid texturing using an ordinary 2-D surface texture map. The solid map transforms a model’s polygons into 2-D texture space without overlap. It then rasterizes the polygons in this space, interpolating the solid texture coordinates across the pixels of the polygon. These stored solid texture coordinates are then read by a texture synthesis ...

Real-Time Procedural Solid Texturing

Shortly after its introduction in 1985, procedural solid texturing became a must-have tool in the production-quality graphics of the motion-picture industry. Now, over fifteen years later, we are finally able to provide this feature for the real-time consumer graphics used in videogames and virtual environments. A texture atlas is used to create a 2-D texture map of the 3-D solid texture coordi...
