Antialiasing in Raycasting Digital Terrain Models
We may use ray-casting methods to render terrain from digital terrain models. In this paper we enhance a terrain renderer in several ways, including application of antialiasing techniques. Also we examine various aspects of antialiasing in terrain rendering. We summarize surface and color reconstruction models, and discuss several vertical antialiasing techniques, including supersampling and ar...
متن کاملSome Notes on Sampling in Computer Graphics
”Nobody will ever figure out how to do antialiasing” said Jim Blinn in his keynote address at Siggraph ’98. Already 21 years earlier, in 1977, he had included antialiasing in a list of unsolved problems in computer graphics which he had compiled together with Martin Newell. And although the quote from 1998 was not meant to be taken totally serious, he included the same problem again in his 1998...
متن کاملFlexible Analog Front Ends of Reconfigurable Radios Based on Sampling and Reconstruction with Internal Filtering
Bandpass sampling, reconstruction, and antialiasing filtering in analog front ends potentially provide the best performance of software defined radios. However, conventional techniques used for these procedures limit reconfigurability and adaptivity of the radios, complicate integrated circuit implementation, and preclude achieving potential performance. Novel sampling and reconstruction techni...
متن کاملSubpixel Reconstruction Antialiasing for Ray Tracing
We introduce a practical antialiasing approach for interactive ray tracing and path tracing. Our method is inspired by the Subpixel Reconstruction Antialiasing (SRAA) method which separates the shading from visibility and geometry sampling to produce antialiased images at reduced cost. While SRAA is designed for GPU-based deferred shading renderer, we extend the concept to ray-tracing based app...
متن کاملAntialiasing with Line Samples
Antialiasing is a necessary component of any high quality renderer. An antialiased image is produced by convolving the scene with an antialiasing filter and sampling the result, or equivalently by solving the antialiasing integral at each pixel. Though methods for analytically computing this integral exist, they require the continuous two-dimensional result of visible-surface computations. Beca...
