Anti-Aliasing is an important addition to any game to improve visual quality by smoothing out the jagged edges of a scene. MSAA (Multisample Anti-Aliasing) is one of the oldest methods to achieve this and is still the preferred solution for mobile. However it is only suitable for forward rendering and, with mobile performance improving year over year, deferred rendering is becoming more common, necessitating the use of post-process AA. This leaves slim pickings as such algorithms tend to be too expensive for mobile GPUs with FXAA (Fast Approximate Anti-Aliasing) being the only ‘cheap’ option among them. FXAA may be performant enough but it only has simple colour discontinuity shape detection, leading to an often unwanted softening of the image. Its kernel is also limited in size, so it struggles to anti-alias longer edges effectively.

Conservative Morphological Anti-Aliasing
Conservative Morphological Anti-Aliasing (CMAA) is a post-process AA solution originally developed by Intel for their low power integrated GPUs 1. Its design goals are to be a better alternative to FXAA by:
Being minimally invasive so it can be acceptable as a replacement in a wide range of applications, including worst case scenarios such as text, repeating patterns, certain geometries (power lines, mesh fences, foliage), and moving images. Running efficiently on low-medium range GPU hardware, such as integrated GPUs (or, in our case, mobile GPUs). We have repurposed this desktop-developed algorithm and come up with a hybrid between the original 1.3 version and the updated 2.0 version 2 to make the best use of mobile hardware. A demo app was created using Khronos’ Vulkan Samples as a framework (which could also be done with GLES) to implement this experiment. The sample has a drop down menu for easy switching between the different AA solutions and presents a frametime and bandwidth overlay.
CMAA has four basic logical steps:
Image analysis for colour discontinuities (afterwards stored in a local compressed 'edge' buffer). The method used is not unique to CMAA. Extracting locally dominant edges with a small kernel. (Unique variation of existing algorithms.) Handling of simple shapes. Handling of symmetrical long edge shapes. (Unique take on the original MLAA shape handling algorithm.) Pass 1
Edge detection result captured in Renderdoc.
A full screen edge detection pass is done in a fragment shader and the resulting colour discontinuity values are written into a colour attachment. Our implementation uses the pixels’ luminance values to find edge discontinuities for speed and simplicity. An edge exists if the contrast between neighbouring pixels is above an empirically determined threshold.
Neighbouring edges considered for local contrast adaptation.
A local contrast adaptation is performed for each detected edge by comparing the value of the previous pass against the values of its closest neighbours by creating a threshold from the average and largest of these, as described by the formula below. Any that pass the threshold are written into an image as a confirmed edge.
This pass collects all the edges for each pixel from the previous pass and packs them into a new image for the final pass. This pass also does the first part of edge blending. The detected edges are used to look for 2, 3 and 4 edges in a pixel and then blend in the colours from the adjacent pixels. This helps avoid the unnecessary blending of straight edges.
The final pass does long edge blending by identifying Z-shapes in the detected edges. For each detected Z-shape, the length of the edge is traced in both directions until it reaches the end or until it runs into a perpendicular edge. Pixel blending is then performed along the traced edges proportional to their distance from the centre.
Before and after of Z-shape detection.
Image comparison shows a typical scenario for AA. CMAA manages high quality anti-aliasing while retaining sharpness on straight edges.
CMAA demonstrates itself as a superior solution to aliasing than FXAA by avoiding the latter’s limitations. It maintains a crisper look to the overall image and won’t smudge thin lines, all while still providing effective anti-aliasing to curved edges. It also provides a significant performance advantage to Qualcomm devices and only a small penalty to ARM.
Image comparison shows a weakness of FXAA where it smudges thin lined geometry into the background. CMAA shows no such weakness and retains the colour of the railing while adding anti-aliasing effectively.
MSAA is still a clear winner and our recommended solution if your game allows for it to be resolved within a single render pass. For any case where that is impractical, CMAA is overall a better alternative than FXAA and should be strongly considered.

So.....I bought a new TU8000. Tizen newbie here.
I keep all my TV/Movies in shares on a Synology Diskstation NAS.
I usually watch through Kodi (on a MeCool box running CoreElec), which I was hoping to do away with now.
What I care about: 1) being able to have menu options which map to my file shares, 2) be able to view in a folder/file list, and 3) sort by either date added OR name.
1 is not problem, but I can't seem to have 2 and 3 together.
I've tried, and I've searched.......
I just can not work out how to get Samsung Tizen to give me this. Sure, I can use Plex. I'm not a big fan, but it comes close. But that also does not seem to give me a folder/file list view AND the ability to sort by date OR name.
Synology's DS Video is available on the Samsung, but is not real nice, and similar limitations.
So at this point, it's continue with my Kodi box for NAS TV/films rather than relying on the Samsung Tizen. I was hoping to remove a device from my setup.
If anyone has any helpful ideas/advice, or tell me what I am missing, it would be most appreciated.

Creating compelling social media visuals can be a very time-consuming endeavor. It's even harder to find the time to write great copy that complements the visuals. To top it all off, there is no guarantee that your post will reach enough people to make it worth your time. In spite of this, social media remains a pivotal tool for sellers to gain traction in the ever-growing Galaxy Store. That’s why we decided to help sellers cut down on the time needed to make great posts with our new social media kit.
Download Social Media Kit for Phone Apps and Themes
Download Social Media Kit for Watch Apps and Watch Faces
This new kit will allow you to quickly add a screenshot of your watch face, theme, or app; drop in a high-res background image, and add a snappy title in seconds. It will then create exact post sizes for the three major social networks--Facebook, Instagram, and Twitter. It’s that easy!
However, we know that creating visuals is only half the battle. Because the holiday season is right around the corner (and with it, a 25%-40% increase in Galaxy Store activity), we wanted to give you all a little extra boost during this time.
We want to help you move up those all-important “top” category lists. During the next few weeks, we will run a content amplification campaign. Sellers who use the new social media kit and post on Twitter, Facebook, and Instagram using their Galaxy Store badge links and the hashtag #GalaxyStoreHolidays will have a chance at being retweeted by one of our social media accounts. The Galaxy Store and Samsung Developers accounts have over 100k followers worldwide!
If you have a bad case of writers block or just want to further cut down on your time spent on this exercise, we have provided some sample copy to get you started:
Suggested Copy (Watch Face): The holidays are here and all the amazing Samsung wearables deserve the best watch face designs! Check out one of my top sellers, [Insert watch face name], to really make that Galaxy Watch standout! [Insert Galaxy Badge Link] #GalaxyStoreHolidays Suggested Copy (Theme): The holidays are here and all those amazing Galaxy phones deserve a great, new theme! Check out one of my top sellers, [Insert theme name], to really make that new Note10 shine! [Insert Galaxy Badge Link] #GalaxyStoreHolidays Just remember these are just suggestions, and it may benefit you to change the wording in order to stand out even more.
This new skill requires the use of Adobe Creative Cloud. Here's how to get started:
Download the Photoshop files from the links above Insert app/watch face/theme screenshot Drop in background image Find free high-res images @ pexels.com or similar sites Insert your headline We recommend keeping it short and simple Write your copy and don’t forget to add your Galaxy Store badge link Start sharing your Tweets and Facebook and Instagram posts You can use buffer.com to help schedule all your posts Always use the hashtag #GalaxyStoreHolidays The Samsung Developers and Galaxy Store accounts will retweet different posts using this hashtag throughout the holiday season There is NO GUARANTEE that yours will be selected, please keep this in mind The more you post the better your chance will be to be seen by more than 100k followers worldwide Don't wait - holiday shoppers await!
