Vertex-based Anisotropic Texturing
(The Eurographics Association, 2001)
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 ...
Perlin Noise Pixel Shaders
(The Eurographics Association, 2001)
While working on a method for supporting real-time procedural solid texturing, we developed a general purpose multipass pixel shader to generate the Perlin noise function. We implemented this algorithm on SGI workstations ...
Compiling to a VLIW Fragment Pipeline
(The Eurographics Association, 2001)
The latest generation of graphics hardware supports fully programmable vertex and pixel/fragment operations, but programming this hardware at a low level is difficult and time consuming. To address this problem, we have ...
Algorithms for Division Free Perspective Correct Rendering
(The Eurographics Association, 2000)
Well known implementations for perspective correct rendering of planar polygons require a division per rendered pixel. Such a division is better to be avoided as it is an expensive operation in terms of silicon gates and ...
Incremental and Hierarchical Hilbert Order Edge Equation Polygon Rasterization
(The Eurographics Association, 2001)
A rasterization algorithm must efficiently generate pixel fragments from geometric descriptions of primitives. ln order to accomplish per-pixel shading, shading parameters must also be interpolated across the primitive in ...
The F-Buffer: A Rasterization-Order FIFO Buffer for Multi-Pass Rendering
(The Eurographics Association, 2001)
Multi-pass rendering is a common method of virtualizing graphics hardware to overcome limited resources. Most current multi-pass rendering techniques use the RGBA framebuffer to store intermediate results between each pass. ...
A Quadrilateral Rendering Primitive
(The Eurographics Association, 2004)
The only surface primitives that are supported by common graphics hardware are triangles and more complex shapes have to be triangulated before being sent to the rasterizer. Even quadrilaterals, which are frequently used ...
