چکیده

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, and can be realized in VLSI with as little as 100,000 gates. The new model also yields a new method for antialiasing synthesized textures. An expression for the necessary box filter width is derived as a function of the texturing parameters, the texture coordinates and the rasterization variables. Given this filter width, a technique for efficiently box filtering the synthesized texture by either mip mapping the color table or using a summed area color table are presented. Examples of the antialiased results are shown.

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...

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 ...

Interactive Solid Texturing using Point-based Multiresolution Representations

This paper presents an interactive environment for texturing surfaces of arbitrary 3D objects. By uniquely using solid textures and applying them to the surface, we do not require an explicit parameterisation in texture space. Various solid textures can be combined by building a constructive texturing tree of space partitions to define the photometric attributes at each location of the object. ...

Sphere Tracing: Simple Robust Antialiased Rendering of Distance-Based Implicit Surfaces

Sphere tracing is a new numerical method for nd-ing the intersection of a ray with an implicit surface. Unlike Newton's method or regula falsi, it is robust, converging if and only if the ray intersects the implicit surface, and it converges on the rst intersection | the intersection closest to the ray origin. It is signiicantly simpler to implement than other robust intersection techniques, su...
