Anisotropic filtering

Anisotropic filtering : the highest quality filtering available in current consumer 3D graphics cards. Simpler, “isotropic” techniques use only square mipmaps which are then interpolated using bi– or trilinear filtering. (Isotropic means same in all directions, and hence is used to describe a system in which all the maps are squares rather than rectangles or other quadrilaterals.)

When a surface is at a high angle relative to the camera, the fill area for a texture will not be approximately square. Consider the common case of a floor in a game: the fill area is far wider than it is tall. In this case, none of the square maps are a good fit. The result is blurriness and/or shimmering, depending on how the fit is chosen. Anisotropic filtering corrects this by sampling the texture as a non-square shape. Some implementations simply use rectangles instead of squares, which are a much better fit than the original square and offer a good approximation.

However, going back to the example of the floor, the fill area is not just compressed vertically, there are also more pixels across the near edge than the far edge. Consequently, more advanced implementations will use trapezoidal maps for an even better approximation (at the expense of greater processing).

In either rectangular or trapezoidal implementations, the filtering produces a map, which is then bi– or trilinearly filtered, using the same filtering algorithms used to filter the square maps of traditional mipmapping.

I wanted to explore the shaders a little bit more, so I am doing it with you guys. You can see the examples with the ball and box with chamfered corners.

Double Refraction is another way to describe Birefringence. Double Refraction is the splitting of a light ray into two separate rays when the original light ray passes through certain anisotropic materials, including polymers and plastics.

To couch it in simpler terms, the single “oncoming beam” splits into two “outgoing beams”.

Polarized Light Microscope

The polarized light microscope uses a polarizer to direct lightwaves in one consistent direction. The light is refracted as it passes through the object under the microscope. The way that the light is transmitted through an object under these circumstances characterizes different materials.

-ISOTROPIC: does not allow cross polarized light through

-ANISOTROPIC: allows cross polarized light through

Photo showing the light changes on veneer. I would like this effect on the animation if possible. Spoke to Shannon about it and he thinks it is possible, and even had a technical name for it - anisotropic!

Let the modding begin!

My new laptop can run Skyrim with max settings at 58-60fps.  my old laptop couldn’t do that with anti-aliasing and anisotropic filtering turned off, and those take a ton of processing power to do on max.

anonymous said:

aww, so uhm can you share your setting when you edit and the order?? i really love the way you edit. :)

well usually i just smart sharpen the original pic then resize it then use the sharpen action i downloaded around ps blogs here on tumblr, i might or might not smart sharpen(usual setting i uses is either the 500 px with 0.3 ratio or the 150/175 px with a 0.3 ratio too) depends on the picture im working with and then i duplicate the bg layer and with that duplicated bg layer i go to stylize filter then diffuse then click on the anisotropic, then i just fiddle around with the opacity layer of the duplicage bg layer and then after that i just erase the parts i dont like thats blurry

Splinter Cell Blacklist

Another aggravating and frustrating issue arose when I got to the campaign mission, Transit Yards, the game would crash on loading the level. All other missions would load fine and play without issue.

So like any other self helper, I got onto google and looked for people that had similar problems and possible fixes. Only one was found, a facebook post that is my issue precisely and dated 2 years ago. No other helpful information with regards to fixes or workarounds.

So like any other determined self helper, I updated all my drivers and did a directx diagnostic. No results, loading up Transit Yards still resulted in a crash but all other missions would load fine and play without issue.

So like any other grim goal oriented and fatally undaunted self helper, I started to change my graphical settings to lower ones. Turning off or down Antialiasing, Anisotropic Filtering, Tessellation, Parallax, Texture Detail, and Lighting. All met with no results, Transit Yards would still crash but all other missions would load and play without issue.

So like any other single-minded laser focused will driven individual self helper, I tried switching to Directx 9 instead of Directx 11. Again, no results, Transit Yards would still crash on loading but every other missions would load and play without issue.

I also tried posting on the splintercell subreddit to see if anyone had my particular issue. Nothing worked, and I was hesitant to try for a pirated crack.

So like a drowning man grasping at air and hoping someone will lend a hand, I tried ubisoft tech support. I stated my issue plainly and my approaches to try address the issue so far. Surprisingly, I got a very quick response from helpful person suggesting I try the generic IT catch all response of clearing out my temp folders, updating drivers, disabling background applications, and doing a directx diagnostic. Knowing they would not work at all, I tried them anyway, and unsurprisingly they did not work. Transit Yards still crashed but all other missions would load and play without issue.

So I reported my findings to the helpful ubisoft support person and got another quick response, this time asking me to upload my directx diagnostic and msinfo. I did. And was told reinstalling would fix it.

So that’s what I’m doing now. A shame my experience with the game is being marred by technical issues because I was really enjoying the game. I like gameplay, the customization, the story is decent, the voice acting for Fisher was decent (although I still prefer Michael Ironside), and the villain voiced (and mocapped) by actor Carlo Rota was pretty good.

Hopefully the reinstall will fix it. If not I’ll just move on to playing Assassin’s Creed 4: Black Flag. And hoping I don’t run into anymore technical issues.

Edit: It did not work, still crashes on Transit Yards.

PointWise 17.2 R2 | 1.0 Gb

Pointwise announces the latest release of its Pointwise computational fluid dynamics (CFD) meshing software featuring an extension of the company’s advanced T-Rex hybrid meshing technique to generate near-wall layers of hexahedral cells.

Near-wall and near-wake hex layer generation is the latest capability added to T-Rex (anisotropic tetrahedral extrusion), one of Pointwise’s hybrid meshing techniques. The technique extrudes stacks of anisotropic tetrahedra off a surface mesh. A post-processing step combines stacks of tetrahedra into either prisms or hexahedra. In addition to reducing cell count and thereby CPU time, most CFD solvers compute more accurate answers with prisms and hexahedra in boundary layers and wakes.

Other features in Pointwise Version 17.2 R2 include new native interfaces to the Edge and LAURA CFD codes, updated native CAD format interfaces, and several user experience improvements.

Pointwise, Inc. is solving the top problem facing engineering analysts today – mesh generation for computational fluid dynamics (CFD). The company’s Pointwise software generates structured, unstructured and hybrid meshes; interfaces with CFD solvers, such as ANSYS FLUENT, STAR-CCM+, ANSYS CFX and OpenFOAM as well as many neutral formats, such as CGNS; runs on Windows (Intel and AMD), Linux (Intel and AMD), and Mac, and has a scripting language, Glyph, that can automate CFD meshing. Large manufacturing firms and research organizations worldwide rely on Pointwise as their complete CFD preprocessing solution

Bonus: PointWise Gridgen 15.18 (all platform)

Gridgen is Pointwise’s legacy software, used by engineers and scientists worldwide since 1984 to reliably generate high quality grids for CFD.
