MIP mapping is a common method used by graphics hardware to avoid texture aliasing. In many situations, MIP mapping over-blurs in one direction to prevent aliasing in another. Anisotropic texturing reduces this blurring by allowing differing degrees of filtering in different directions, but is not as common in hardware due to the implementation complexity of current techniques. We present a new algorithm that enables anisotropic texturing on any current MIP map graphics hardware supporting MIP…

Fast and Flexible High-Quality Texture Filtering With Tiled High-Resolution Filters

This work presents algorithms for extremely fast convolution on graphics hardware, which are able to deploy high-resolution filters, i.e., filters that are sampled at a much higher resolution than the width of the filter kernel.

Perception-Oriented 3D Rendering Approximation for Modern Graphics Processors

This work proposes a perceptionoriented runtime approximation model for 3D rendering by leveraging the inner-relationship between anisotropic and isotropic filtering, and provides a low-cost texture unit design for enabling this approximation.

Hexagonal storage scheme for interleaved frame buffers and textures

The analysis of memory access patterns in rendering typical 3D graphics scenes shows that the hexagonal storage scheme can reduce rendering performance degradation due to bank conflicts by an average of 10% compared to the traditional rectangular storage scheme.

Feline: fast elliptical lines for anisotropic texture mapping

This paper describes a new texture filtering technique called Feline, which uses an underlying space-invariant (isotropic) filter with mipmapped data, and so can be built on top of an existing trilinear filtering engine.

Survey of Texture Mapping

The fundamentals of texture mapping are surveyed, which can be spilt into two topics: the geometric mapping that warps a texture onto a surface, and the filtering necessary to avoid aliasing.

Texture-map computations can be made tractable through use of precalculated tables which allow computational costs independent of the texture density, and the cost and performance of the new technique is compared to previous techniques.

Texture potential MIP mapping, a new high-quality texture antialiasing algorithm

A refined version of the texture potential mapping algorithm is introduced in which a one-dimensional MIP map is incorporated. This has the effect of controlling the maximum number of texture samples

Adding long long was proposed previously by Roland Hartinger in June of 1995, in J16/950115=WG21/N0715, and almost a decade later, the world looks different: long long is part of C99, and many major C++ compilers support it.
