![]() ![]() The output name can be something totally different to the input name, but I tend to use something similar, as it helps to identify it when you have a folder full of files. After a short wait, you can download your animated GIF. Change the size of the GIF, apply a filter, change the DPI, and more. Below is a general principle, where input is the actual name of the video, following by the video format and the name that you want your gif to be. How to convert MP4 to GIF Upload your MP4 video. Once you have selected the video that you want to convert, open your terminal and change directory where your video is saved. Make sure to install ffmpeg using your distribution’s package manager: sudo apt install ffmpeg I downloaded the video from YouTube using youtube-dl and then I trimmed the video to get the first 5 seconds. Choose Files From Device From Dropbox From Google Drive From Url Max file size 1GB. Convert MP4 to GIF, WebM to GIF, MOV to GIF, AVI to GIF, FLV to GIF, MPEG to GIF, and 3GP to GIF. In this example, I will use the Linux Mint 20 new feature presentation video. VistaCreate is the only GIF converter you need to transform any video to GIF quickly and easily. We also have a good collection of ffmpge usage examples. Kapwing supports most video file types including MP4, MOV, WebM, and many more, so you can convert any video to GIF for any reason. It can also resize video on the fly without compromising the quality.įFmpeg is a powerful tool and can be used for various scenarios, if you are curious here is the official documentation. Convert your entire video to a GIF or trim the part of the video you want to make into a GIF in only a few clicks. Streaming information is included in MP4 using a distinct hint. This tells FFmpeg to take my-animation.gif as the input, signified by the -i flag, and to convert it to a video called my-animation.mp4. ![]() MP4 can embed any data over private streams. A new window will pop up on the screen, where you can import your WebM file. The GIF Maker is the primary tool to create a GIF from your WebM file. Normally it is used to share videos over internet. Please navigate the program’s Toolbox from the top menu bar and select the GIF Maker tool. FFmpeg is a video and audio converter that can also grab from a live audio/video source. MP4 MP4, also known as MPEG4 is mainly a video format that is used to store video and audio data. ![]()

![]() The transpose of a rotation matrix will always be equal to its inverse and the value of the determinant will be equal to 1.In a clockwise rotation matrix the angle is negative, -θ.In 3D space, the yaw, pitch, and roll form the rotation matrices about the z, y, and x-axis respectively.Then P will be a rotation matrix if and only if P T = P -1 and |P| = 1. Moreover, rotation matrices are orthogonal matrices with a determinant equal to 1. One way to think about 60 degrees, is that that's 1/3 of 180 degrees. So this looks like about 60 degrees right over here. So if originally point P is right over here and we're rotating by positive 60 degrees, so that means we go counter clockwise by 60 degrees. This implies that it will always have an equal number of rows and columns. It's being rotated around the origin (0,0) by 60 degrees. A rotation matrix is always a square matrix with real entities. These matrices rotate a vector in the counterclockwise direction by an angle θ. 2 Geometry is, along with arithmetic, one of the oldest. 1.Ī rotation matrix can be defined as a transformation matrix that operates on a vector and produces a rotated vector such that the coordinate axes always remain fixed. Geometry (from Ancient Greek (gemetra) 'land measurement' from (g) 'earth, land', and (mtron) 'a measure') 1 is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. In this article, we will take an in-depth look at the rotation matrix in 2D and 3D space as well as understand their important properties. These matrices are widely used to perform computations in physics, geometry, and engineering. Rotation matrices describe the rotation of an object or a vector in a fixed coordinate system. Similarly, the order of a rotation matrix in n-dimensional space is n x n. If we are working in 2-dimensional space then the order of a rotation matrix will be 2 x 2. When we want to alter the cartesian coordinates of a vector and map them to new coordinates, we take the help of the different transformation matrices. Furthermore, a transformation matrix uses the process of matrix multiplication to transform one vector to another. Geometry provides us with four types of transformations, namely, rotation, reflection, translation, and resizing. ![]() The purpose of this matrix is to perform the rotation of vectors in Euclidean space. You will learn how to perform the transformations, and how to map one figure into another using these transformations. ![]() Rotation Matrix is a type of transformation matrix. In this topic you will learn about the most useful math concept for creating video game graphics: geometric transformations, specifically translations, rotations, reflections, and dilations. ![]() ![]() ![]() Sagitta the Arrow is a dim but delightful constellation that sits at the upper left of Altair. Smaller and less prominent but quite striking is the exquisite little Parallelogram, which hangs just below blazing Vega in Lyra. The largest and most prominent asterism (unofficial star pattern) associated with the Triangle is the Northern Cross, comprised of the brightest stars in Cygnus. Once you’ve spotted the Summer Triangle, you can use it to find other sights. In fact, Deneb is one of the most luminous of all stars-an astounding 200,000 times brighter than our Sun! The light we see from Deneb left the star about the time the Pyramids of Egypt were being built. How can this be? The only way Deneb can both be farther away yet appear equal in brightness is if its actual (or “ intrinsic brightness”) is much greater than the others. But looks can be deceiving! We know that Deneb is more than 100 times farther from us than Vega or Altair, yet it appears nearly as bright. ![]() Put another way, their “ apparent brightness” is roughly the same. The three stars of the Summer Triangle appear to be about equal in brightness. A light-year is the distance light travels in one year-a big, BIG number! Apparent Brightness Whereas Vega and Altair are relatively close to us in astronomical terms-25 and 17 light-years respectively-Deneb is much farther away, an estimated 2,600 light-years from Earth. Alas, Deneb has never starred in a major motion picture, but it has other claims to fame. Number three in the Summer Triangle and the 20th brightest star is Deneb, which marks the tail of Cygnus the Swan. We don’t know if Altair is surrounded by any planets, so Altair IV may or may not exist. Altair is the 2nd brightest member of the Summer Triangle and the 13th brightest star. In the 1956 film “Forbidden Planet,” the fourth planet in the Altair system (Altair IV) is home to the relics of an ancient alien civilization and to an eccentric Earth scientist and his beautiful daughter (Walter Pidgeon and Anne Francis). Back in the real world, we’ve yet to hear anything from the possible inhabitants of the Vega system, but researchers are listening to Vega and thousands of other stars every day, just in case.Īltair, in Aquila the Eagle, is another Hollywood star. ![]() The 1997 movie version features actress Jodie Foster’s quest for the senders of the Vega message. In Carl Sagan’s novel “Contact,” Vega is the source of the first message ever received from an alien civilization. Vega in the constellation Lyra the Lyre is the brightest of the trio and the 5th brightest of all stars. The three stars of the Summer Triangle appear similar in brightness. Night Sky Map for October 2023: Constellations, Then and Now ![]() ![]() ![]() She found her way through sheer force of will.” The thing that always amazed me about her life, is that no one showed her. Growing up in Soweto, our dream was to put another room on our house, maybe have a driveway, maybe someday, a cast iron gate at the end of the driveway because that’s all we know.īut the highest rung of what’s possible is far beyond the world you can see. We tell people to follow their dreams, but you can only dream of what you can imagine, and, depending on where you come from, your imagination can be quite limited. That my ideas thoughts and decisions mattered. Not culturally, but in the sense of believing the world was my oyster, that I should speak up for myself. When I look back, I realize she raised me as a white kid. “My mom raised me as if there were no limitations on where I could go or what I could do. The specter of racism hangs over these chapters too, but they illustrate his mettle and can-do attitude - a belief that life would always work out for him - which is a direct result of his mother. ![]() He also was a DJ and had a dance crew, which in one of the more cringeworthy chapters, failed at a gig spectacularly. Some of the lighter chapters follow Noah’s adventures in his late-teens and early twenties, where he was an entrepreneur selling pirated CDs, stolen goods and offering loans. In the fantastically self-narrated audiobook, Noah shares these darker moments with a casual and humorous delivery that will make you feel guilty for laughing out loud at memories so painful. ![]() Each school year was a challenge to fit in. Black relatives treated him differently, because they perceived him as white. He speaks often of not knowing where to belong and feeling largely isolated and disconnected from others. So, his mother found another Colored woman to walk with him while in public, while she trailed behind. That meant neither his mother, who is Black, nor his father, who is white, could be seen in public with him out of fear they would be arrested, and he would be taken away. There’s enough social and political history given to help fill in knowledge gaps, but he doesn’t belabor injustices, instead he shows how they manifested and impacted his family, mainly through the experiences of his mother and biggest champion, Patricia.įirst, as the title suggests, Noah was born a crime as it was illegal for white and Black people to date. Throughout the memoir, Noah seamlessly shifts the narrative from humorous coming-of-age memoir to the somber realities apartheid and post-apartheid politics had on his family and the Black and Colored (apartheid categorization for biracial individuals) communities. He understands misogyny from men in power, systemic racism, senseless violence and living at the poverty line because that was his daily life for more than 20 years in South Africa.įor elder Millennials, “Crime” offers a first-hand account of apartheid - from someone around our age - that those of us in sheltered white communities didn’t have the world knowledge to grasp in middle school current events discussions in the early 1990s. It’s easy to think of Noah as a comedian simply observing and reporting on the world’s happenings, but after finishing “Born a Crime,” you understand that he comes at this commentary from a lived experience. The man-on-the-street interviews at Trump rallies are cringe-worthy perfection and expertly expose the hypocrisy of his most ardent followers. I’m not a regular watcher of The Daily Show, but I’ve come to appreciate the pitch-perfect coverage of American politics under Trevor Noah’s tenure at the anchor desk. ![]() ![]() ![]() Is there violence, mistrust, or even a family feud? Perhaps there is abuse, neglect, or sexual abuse.Īll of these little bits of information come together to paint a picture of how a person’s family and relationships affect them. Are the relationships harmonious? Are there friendships or even best friends? Are they in love? Perhaps there is even hostility in the relationship. Dating is a dotted line etc.įinally, we need to look at the emotional nature of the relationships. ![]() Marriage is a solid line, divorce has two strokes through it. Otherwise, we just have a bunch of shapes on a page. The next step is for us to add how the relationships are brought together. We can add as much personal information as is needed. ![]() At this point, we can add ages, names, dates of birth, and death. Pets even get a jersey! The shapes begin to tell us how many people and what sex they are. Squares are males, circles are females, and triangles are pregnancy related. So what is in a genogram?Ī genogram uses shapes to convey meaning. It is a great tool for showing the changes and progress on their healing journey. It is then that I show them their old genograms and ask what has happened to make these changes happen. After a few months, we revisit and there are a few less squiggly lines and a few less colours. Colour everywhere and squiggly lines as far as the eye can see. Their genograms often look like a child got hold of the textas. When I work with families, it is often when they are on the brink of an all-out war. They are a picture of what is happening now. It can also help them see their own struggles using a strengths-based way of working through the issues. Many young people who are being abused struggle to speak about it, however showing them how to draw a genogram can lead them to draw the abusive relationship which opens the dialogue. Genograms also help our clients to put a framework together that explains their circumstances. Because of the pictorial nature of genograms, it easily shows issues and concerns that might not be spoken about usually in a non-threatening manner. It can also help us to see patterns within those relationships and generational patterns which are affecting our clients. Why would I use a genogram?Ī genogram is a really useful tool for helping us to understand the key people and relationships in a client’s life. Most social work practitioners in personal and family therapy use genograms alongside sociograms for personal records and/or to explain family dynamics to their clients. Genograms are now used by various groups of people in a variety of fields such as medicine, psychology, social work, genetic research, education, and youth work to name but a few. This new system visualized the client in the context of other relatives including parents, grandparents, spouses, siblings, children, nephews, and nieces. Genograms were first developed in clinical psychology and family therapy settings by Monica McGoldrick and Randy Gerson and popularized through the publication of a book titled Genograms: Assessment and Intervention in 1985. It goes beyond a traditional family tree allowing the creators to visualize patterns and psychological factors that affect relationships. A genogram is a picture of a person’s family relationships and history. ![]() ![]() ![]() Some underprivileged gamers will not have the edge of the said game in question if they don't have a controller because part of the view will be obstructed by their hands since the control mechanism is on the screen, whereas you have the full view of the game if you use a controller which can improve your gaming experience slightly, as you don't obstruct your screen with your hands.īut over here, I guess it all boils down to your consciousness. Even though the game did supports it, chances are not many gamers who play the games can afford a game controller (maybe that's too far stretch, but for me, an XBox One X controller cost about 1/10 of my monthly salary, so it's tad expensive for me). ![]() Saying it's a grey area is like saying using mouse and keyboard on a XBox One/Series game that has support natively in the game because the developer added it is a grey area as well. Having an advantage due to your choice input method is fine. ![]() If the developers themselves added support as a means of input then it's totally legit. Fast hardware is no substitute for skill, but there's a good reason esports pros almost universally run on 144Hz and higher refresh rate displays these days.It's not a grey area in any way shape or form. We're not going to say everyone should rush out and upgrade their GPUs and monitors, but if you've played on a 144Hz display with a sufficiently potent GPU (like GTX 1070 / RX Vega 56 or above), there's a very different feel to the game. Something else to note is that the 144fps framerate cap has been removed, which opens the doors to higher framerates and advantages for those with better hardware. Earlier versions of PUBG favored Nvidia more, but the retail release with the latest drivers shows the RX 570/580 and Vega cards mostly on par with the GTX 1060/1070/1070 Ti. Regardless, the GTX 1060 3GB and 6GB deliver a great value for your dollar.ĪMD's GPUs are also good, though often a bit behind the equivalently priced Nvidia GPUs. PUBG is still in active development, despite leaving Early Access, though we don't expect performance to change as much going forward. The previous-generation GTX 970 isn't too far off the pace of the GTX 1060 3GB, but if you're shooting for 60 fps with a more entry level graphics card, expect to drop the settings down to low to achieve that framerate. At 1080p medium, though, it averages over 100 fps and should never drop below 60. What will it take to run Battlegrounds at 60 fps or better at 1080p? According to our performance analysis, the 1060 3GB is powerful enough to run PUBG at an average 60 fps at 1080p Ultra settings, while dropping as low as 39 fps in its most intense moments. There you'll see more of a performance dip than you would with a quad-core CPU. If you're doing other stuff like livestreaming, however, you'll want to keep some extra cores handy.Īlso worth noting is that dual-core CPUs (Celeron/Pentium, and earlier Core i3) may struggle, particularly with minimum framerates that are likely to crop up in the games' most demanding moments.
