   Anisotropic filtering
Hi, i need realize software anisotropic filtering, help please, where i can find: theory, algorithms ? On wiki not useful information, thank.
I just found some with a quick search:http://geometrian.com/data/research/atf/AnisotropicTextureFiltering.pdfhttp://onversity.com/doc/article/filtre-spaf.pdfhttp://www.mpi-inf.mpg.de/~khildebr/papers/smooth.pdf I'm sure there are many, many... many different implementation of AF, so take them just as example..;thank and, possible example realisation software ?or more simple example, and i need software implementation, and not hardware.;I understand it uses a sample on an ellipse rather than a circle (like the square with bilinear filtering), but I do not understand how to calculate this ellipse, please tell me. I understand that the major and minor radius of the ellipse depend on the inclination of the plane of the screen space, so you can use a vector along which to interpolate texels (x2 -> 2 texel x4 -> 4 texel ...)?;Isn't that something graphics card can do for you nowadays?;can, but i need namely software implementation:);Help, please.;Here another elliptical-like implementation (well documented imo): http://ronaldperry.org/FelineSig1999.pdf and another here: http://graphics.cs.aueb.gr/graphics/docs/papers/I3D11_EllipticalFiltering_draft.pdf Here is a recursive implementation: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.106.5735&rep=rep1&type=pdf If you still have issues with the AF filtering it's better you ask into Graphics Programming and Theory forum.;thanks for help);What can you say about EWA filter, whether it is good for the software implementation ?
