Graphics Definition and 116 Threads

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...

Hi Anyone knows a nice and simple graphics library for C (Windows 7) that is not openGL nor GT. All I want to do is plot pixels on the screen. In a window or directly in the console.

Hello all, I'll try to make myself clear... My goal here is to plot a function f(x,y) in 3D. But, instead of using the Plot3D[] function, I made a table of Plot[] for, say, several values of the x variable. So I'm now with a list which looks like this ...

1 being the worst you can buy right now, 100 the best you can buy right now i got a mobile intel R 4 series express chipset family with a booster: nvidia geforce G210M cuda 512Mb i think that's right. >.> could be wrong though :s the dxdiag window thing just says the mobile intel r 4 stuff but...

Hi everyone, I'm trying to put graphics into a lab report in LaTeX, and the images simply won't show up. I've tried doing it several ways, including this: \begin{figure}[h] \begin{center} \includegraphics{SeminalEmulsion.jpg} \caption{default} \label{default} \end{center} \end{figure}...

I have a question: hope this fits under "Calculus" topic. I am trying to embed vector graphics in my Word documents. MathCAD does this quite nicely for xy-plots, but MathCAD is awkward for constructing vector fields like those you'd find in electrodynamics. I could use Maple, but those embeds...

Hey guys, Recently my computer has been hit with the nvlddmkm.sys error. Basically the screen blinks black every few minutes and then finally the monitor dies on me and requires a reboot before I can use my computer again. I have found a temporary fix, by deleting the nvlddmkm.sys file in...

I'm looking into the 3d graphics equations for light traveling through a medium. Specifically, light traveling along a ray to the eye. One of the components is called in-scattering, where light is scattered into this ray to add light. They define a phase function phase(v', v) which describes...

"Real time" Vs. "Rendered" (referring to graphics) what does this mean?

I have seen drivers that allow you to use one of a SLI cards as a physics processor. I was wondering if boards with a built in, but unused, graphics chip could be turned on and used as a physics processor. I'm not really concerned with the "why would you want to" but more the "is it possible".

Why do computer graphics programs like raytracers treat light almost exclusively as a particle rather than a wave?

Anyone here can recommend me a book that teaches on how to use mathematics like Integration, and Differentiation? I found one but it just use Linear Algebra which is so common in most books. Gamedev.net's users said that it is use in physics and animation, how can I do that? I don't get how it...
