If you are asking for advice on choosing classes or career prospects, please post in the stickied Career & Education Questions thread. Rule 4: No career or education related questions If you ask for help cheating, you will be banned. Do not ask or answer this type of question in /r/math. Homework problems, practice problems, and similar questions should be directed to /r/learnmath, /r/homeworkhelp or /r/cheatatmathhomework. This includes reference requests - also see our list of free online resources and recommended books. If you're asking for help learning/understanding something mathematical, post in the Quick Questions thread or /r/learnmath. Requests for calculation or estimation of real-world problems and values are best suited for the Quick Questions thread, /r/askmath or /r/theydidthemath. For example, if you think your question can be answered quickly, you should instead post it in the Quick Questions thread. Questions on /r/math should spark discussion. Rule 2: Questions should spark discussion Please avoid derailing such discussions into general political discussion, and report any comments that do so. In particular, any political discussion on /r/math should be directly related to mathematics - all threads and comments should be about concrete events and how they affect mathematics. Choose cross-eyed viewing or parallel viewing, then move your eyes to merge two images.All posts and comments should be directly related to mathematics, including topics related to the practice, profession and community of mathematics. This switch enables stereopsis of the polytopes. "Flat, Cross, Parallel" Switch (in index pages) You can also change the marking color in the same way with "Hue". The angle between the color light sources varies every time you tap "Angle". Tapping each button saves, shares or sends a content with one of the file extensions. You can capture still and moving images on the screen. "English" button, which is revealed with a non-English article, takes you to the equivalent in English. This button provides the links to Wikipedia articles describing the polytopes. If you switch this setting to "Mark", one of the cells or faces of each polytope will be marked in your selected color. When this setting is switched to "Sync", the light sources revolve in synchronization with the rotation of polytopes. You can choose which to use to illuminate the polytopes. This button toggles between colorful and white light. Swiping left and right switches between 4D and 3D. Swipe the screen of your device up or down with three fingers to see another polytope of the same dimensions. These gestures are only available for the 4D polytopes. Pinching in and out with two fingers starts rotation between the hidden fourth spatial axis and the other axes. Buttons on the screen offer some effect options that can be applied to the polytopes, which helps you understand four-dimensional space.įlick the polytope currently displayed with one finger and it will rotate in our usual three-dimensional space. Simple touch gestures let you intuitively manipulate those geometric figures. Have you ever wanted to see and touch four-dimensional objects? 4D Polytopes is a real-time visualization app that renders the four-dimensional convex regular polytopes such as the tesseract as well as the three-dimensional ones known as the Platonic solids.
