Graphics Definition and 108 Threads

Goal/Background I've taken these courses before(from different college/sources but didn't resonate) So my current career goal is to get into computer graphics industry or research. Open to both game engines or simulation graphics Academic goal is to prepare myself for upcoming Computer...

Desired output similar to image, but without the objects and with better wave interference: I tried plugging the following into wolfram (I specifically want the values to be adjustable): plot z= H*e^(-m*sqrt((x-a)^2+(y-b)^2))*sin(k*(x-a)+k*(y-b) -w*t) +...

I've been reading Computer Graphics: Principles and Practice by Folly and I've encountered the following paragraph in chapter 1.5. I haven't understood how he got to the result in the following calculation, that if there exists a single 100W light bulb, emitting an order of ## 10^{12} ##...

May I recommend math3d.org as a website for making 3D-Graphics for fresh_42's page on List of Online Calculators for Math, Physics, Earth and Other Curiosities. I also might recommend cloudconvert.com to make .gifs. It is simpler than ezgif.com, mainly because it is not so feature rich. Here...

I found a refurbished Quadro M4000 for about $250. I'm wondering if I should get this or a new card for about the same price. The M400 refurbished comes with a 4 year extended warranty so basically $300 with a 4 year warranty.

I've been learning Python and I've got a program to generate Knight's tours on a chessboard. The output is in the format A1-C2 ... What software would I need, for example, to produce an animation of the knight hopping round a chessboard?

Here is a NY Times article on this. They were recognized for their work on three-dimensional computer graphics and get $1,000,000. Besides Hollywood special effects, their techniques are used in video games, and virtual reality (more useful now in the age of social distancing).

Summary: Physics Graphics Simulation I am interested in modeling physics using graphics simulations. I took a python course with CS majors and one of the assignments was to simulate a planet orbiting a star. That being said, I was wondering if anyone knew of any good resources that I could...

Hi all, I am interested viewing graphics of transition states in lepton fermion scattering, and various similar high energy collisions. Does anyone know where I could view these animations?

I thought this was pre-rendered, but it's a real-time benchmark using the unity engine.

I would like some advices to reproduce graphics like this. Particularly, I would like that each straight segment has an arrow in the middle.

Hello, Does anyone know of a science forum that deals with far out, controversial theories & ideas? This would be similar to the science fiction forum here at PF but may even be more outlandish, however postings would receive serious consideration. I have made some simple animations that I...

Hello, I am having trouble comprehending how grids are made and defined in computers. What is the unit that they use and how is it defined ? I know that softwares use standardized units of measure (measurement) such as centimetre. Basically, how is a 3-Dimensional Space created in computers...

Hi guys, I have a webGL application and my understanding is there is no option or at least the option to make thick lines is not working so I thought I would try to write my own routine. I suppose I could just make a double plot of the data just off-set a bit but I'm not exactly sure how to do...

Hi all, I am trying to understand a few basic concepts about cosmology and the CMB, but I am not getting the information presented in these graphics. I've seen them a million times, and I generally just take it for granted without close examination, but now it's bothering me. (these come from...

Hello All, OK, I have been programming since the early 1980's. Programmed in many different languages along the way such as Pascal, C++, C, Visual Basic, and some C# (among others). I pretty much program so that I can model physics. I find it GREAT way to actually understand the physics...

Hi all! I'm currently working on a graphics/physics engine. The following Wikipedia page was extremely helpful in making rectilinear collisions look natural: https://en.wikipedia.org/wiki/Elastic_collision#Two-dimensional Specifically, the very general vector form of the equation on the bottom...

A https://driven2services.com/staging/mh/index.php?threads/18929/ about Java prompted me to ask about graphics in Java and C#, especially from the standpoint of teaching. I know how to create graphical applications in Java using Swing, but I know very little about C#. Swing applications have a...

Hi, Jake here. I've created some graphics about solar cells that covers high level, general info and even delves into some atomic-level subjects. However, I'm no physicist and I'm sure it shows. If any of you could take a quick look at my work and review for errors, that would be awesome. My...

Hi All, Not sure if this is the right place for this thread but it seemed like it was. I have been trying for two whole days to get some plotting tools up and running that will work with my: OSX 10.8.5, Xcode 5.1. I have tried MathGL, Plplot, Gnuplot, Chplot, matplotpp, etc. I get errors...

The answer is E. Since the line is passing the parable at x = 1 and 2 I used between these values to satisfy the inequality(x − 1)4< (x − 1)X = 1,5 (1,5 -1)4 < (1,5 -1) 0,0625 < 0,5 Is this correct?

I have plenty of experience of other systems, from right back to Calcomp pen plotters and the first graphics terminals up to OpenGL, but I haven't done any graphics programming for a few years and I've never programmed graphics on Windows before. So the question is, what libraries...

I am new to the world of computer science. I learned C language last year in my university. I also have a basic knowledge of OOP concepts and C# I want to learn Computer Graphics. I found this book named "Computer Graphics Using OpenGL by F.S. Hill" in the Library. The copyright year of the...

I am planning to get a HP laptop with 2GB dedicated graphics card, but I heard that laptops with dedicated graphics easily burn down. Is it true, and are there anyways to prevent this from happening? Because I heard that you can switch between integrated and dedicated or something like that. And...

I haven't bought/upgraded desktop pc since 2007, and haven't been seriously following trends since. So, this morning, after all night researching about processors (it was very difficult to classify them by quality, not like old Pentium 1-4 days. In fact, I couldn't even determine what generation...

I was numerically solving the wave equation earlier just to produce a simple illustration of a vibrating string and my computer was working pretty hard. Then I realized how many video games nowadays have such awesome graphics with things like water, waves, motion in general, etc... Are these...

I used to play League of Legends, but I stopped playing it because my screen would turn a bunch of different colors and freeze. I set up a fan to blow inside the computer, and that kept it from freezing for a while, because I guess it was overheating, but then it started freezing even though...

I'm currently discarding tons of paper for math practice and I wonder if a tablet is a good replacement. Is it as comfortable? Is it better?

Hi to all. I want your opinion about which software is the most suitable for rendering 3D graphics in order to include these as figures in manuscripts, papers etc. I have seen many papers such as in Nature Physics, Nature Photonics etc that some 3D figures are really awesome. Especially, i...

Came across some rather [to me] incredible views of some large scale structures our universe...Check out the large graphic here: http://en.wikipedia.org/wiki/Galaxy_filament and if interested, also click on the additional illustrations just below...

Is this graphics demo real or fake? I don't think that any PC hardware exists capable of running this graphics engine, and probably won't for at least 10 years.

Can anyone recommend me a device that has an electronic stylus and pad to which I can write, and my work is automatically saved into some format readable by a computer? The device should be wireless and thus have its own battery, and it should ideally (like the Kindle) have a memory so that work...

http://kotaku.com/5961994/what-skyrim-looks-like-when-youre-running-100-mods-at-once Apparently this was running on 100 different graphics and texture mods simultaneously. And it probably ran at 5 frames per second (sarcasm).

My Texas Intrusments graphics calculator recently had some liquid spilt over it and therefore doesn't work anymore. I'm now wondering whether it's worth spending some $200 for a new graphics calculator or whether I should just settle for a simple Casio FX100AU? I'm in an Electrical Engineering...

I was thinking about upgrading my graphics cards from two HD 5870's to either two HD 7970's or two GTX 670's. Right now I have an 850W power supply, which probably isn't enough for those two cards. What PSU might you recommend for the cards I listed? I heard the GTX 670 and 680 are very close...

Dear all, In Java and using Java3D library, I have created a GUI for viewing finite element quad element meshes. I am facing two problems with the graphics: 1. In order to draw the meshes, I draw the quads and the edges separately so that I am able to remove one and leave the other on...

Hello! I'm trying to make an easy MATLAB programme in which you can plot your graphs, change the linewidth, and linestyle in the graphs you want etc. I've managed to use to dialog windows in MATLAB and write a loop which plots a given function. Now I want the programme to ask the user for the...

Hi I have the following graphic: Graphics[{Opacity[0.5], Rectangle[{0, 0}, {1, 3}]}] Say I want opacity to vary with x, e.g. with the expression opacity = x^2. Is there a way to do this? I checked out the "Help", but there were no examples of a varying opacity. Niles.

I have problem like this:recetengular cells,each of the cells should be colored.I have tried with NCL-NcCAR but it is too complicated to write script for me and I do not want to waste time.Can anyone tell me about free software?

I have a for loop spitting out 60 graphs that I have to save to a file. I have to rename them anyways, so saving them by hand is not the issue. I'm wanting know how to maximize the screen and iteratively name the figures. i.e. my code looks like for i = 1:30 (stuff) figure(i) do...

I have made a java code which displays a blue sphere and let's you control with the mouse where its illumination comes from. (its actually a circle and some parts are painted white/blue/black depending on the mouse position to make it look 3D) here is the code import javax.swing.*...

I've got four nvidia 580s runnIng in quad SLI, but they are just not cutting it for me anymore speed wise. Any suggestions? Money is not an issue.

I have a question are there any books that might show someone who is fairly new to computer programming how to add images for a simple game that is not just text based in c++? It mostly just be something fairly simple, like a side scroller(that would probably be as complex as I would want it for...

In the context of Computer Graphics, what is a bilinear patch?

I am trying to understand how light works in computer graphics. Especially OpenGL 3+. So I was given a paper that says how to calculate light. It says "normalise the vectors before taking the dot product".How do I normalize vectors and why? I have to compute the normals to a vertex. What is a...

Can someone explain to me how fluids are simulated using particles? What equations to solve? How to update the particle positions? How awfully computer intensive is the algorithm? Can a simulation using a 100 * 100 * 10 grid run okay on the average computer? The more I read the more I realize...

When it comes to graphics (what I have learned) is that what you see on the screen is data placed in a memory (video buffer) and then the data or pixel is then plotted onto the screen. So when you manipulate the data in the video buffer you will also manipulate the pixels on the screen. Then...
