i currently writing a program to implement Marching Cube using C++ and Opengl. However, my best reference is only from http://local.wasp.uwa.edu.au/~pbourke/geometry/polygonise/ in the web, the provided codes are written in C. my problem here is that i don't understand the triTable and edgeTable and how they are related. can anyone h...
In Maya, I have a list of constraints gathered by the following code. I want to iterate the constraints and query the targets for each of them: cons = ls(type='constraint') for con in cons: targets = constraint(query=True, targetList=True) The problem, there is no general constraint command for manipulating all constraints. Inste...
I'm primarily a programmer and always have the same issue when starting new projects: I have no artistic bone in my body. But you can't always afford an artist. What resources can I use for graphics? I'm primarily looking for free 3D models in various file types. They don't have to be elaborate, but should work for rapid prototyping....
I have a 3D application in WPF which basically is supposed to zoom in and out as the MouseWheel event is fired. I have attempted to subscribe everything possible, but can't find what it is which is handling it. Is there a way to find out what is? Or is there a way to have the event not handled, or for an encompassing UIElement to get to...
Rasterisation (triangles) and ray tracing are the only methods I've ever come across to render a 3D scene. Are there any others? Also, I'd love to know of any other really "out there" ways of doing 3D, such as not using polygons. ...
I want to play around with some graphics stuff. Simple animations and things. I want to fool around with raytracing too. I need help finding a library that will help me do these things. I have a few requirements: Must be able to do raytracing Must be for a high level language (python, .NET, etc.). Please no C/C++ Must have good documen...
Hello, I am trying to create a short animation of an object rotating in 3D space..I have all my images ready..I would like to know how I can change from one image to the other without the transition moves being shown Thank you Edit: What i mean is that instead of having a bouncing ball which all i need to do is move the ball in each fr...
Hi, I extended a Canvas3D and then I override the method "postSwap()", but my odd-even line effect is flickering a lot, what could be another good point for inserting this process? public void postSwap() { Graphics2D g2 = (Graphics2D)this.getGraphics(); Map map = new HashMap(); map.put(RenderingHints.KEY_ANTIALIASING, Render...
I want to achieve the effect of a 2D image I have but a little inclined, for example a plane, I want the image can be rotated about its axis Y. .. anyone can help me with some idea of how to do ..** ...
There are many 3D UI engines in SourceForge and other opensource forum, I would like know which is best one you used? Support D3D in Windows Provide UI Builder tool Support Auto Layout Easy to do localization thanks. ...
I'm looking for a 3D graphics library for a Java web app. Could use some recommendations - only open source, though. Edit: I don't really care how the graphics are output - Javascript/applets/canvas/flash but I want to write the graphics logic in Java. ...
I just found out about Google's O3D project, for rendering 3D graphics in Browsers using html and javascript. It seems nice, although the graphics are about 5 years outdated as far as I could see. Has anyone tried it out? ...
I want to be able to move a particle in a straight line within a 3D environment but I can't think how to work out the next location based on two points within a 3D space? I have created a struct which represents a particle which has a location and a next location? Would this be suitable to work out the next location to move too? I know ...
I want to test my 3d rendering engine as it gets developed, but I am using really lame objects like COLLADA models and such. I was wondering if anyone knew about a repository where one could download full 3d scenes, like cities, but not full levels. ...
I've installed wings 3d on mac osx and I'm loving it. The problem is I can't do any fancy renderings. I've downloaded and installed YafaRay-0.1.0.305-OSXintel10.5 and I can't seem to get it to work. The wings3d manual states that on mac os you export the xml file from wings 3d, but you make the rendering from Terminal, calling yafaray w...
I'm trying to move my game development into the third dimension, but I'm having a bit of troubles understanding what I actually have to do. I've created a 2D MMORPG before using C and SDL, which wasn't too hard. But I can't seem to find any useful resources explaining how 3D programming actually works. I have a basic understanding of the...
I'm building a simple solid modeling application. Users need to be able to manipulate object in both orthogonal and perspective views. For example, when there's a box in the screen and the user clicks on it to select it, it needs to get 'handles' at the corners and in the center so that the user can move the mouse over such a handle and ...
Quaternions are arguably an appropriate choice for representing object rotations internally. They are simple and efficient to interpolate and represent a single orientation unambiguously. However, presenting quaternions in the user interface is generally inappropriate - Euler angles are generally much more familiar to users, and their v...
I am trying to figure out what algorithms there are to do surface reconstruction from 3D range data. At a first glance, it seems that the Ball pivoting algorithm (BPA) and Poisson surface reconstruction are the more established methods? What is the established, most robust algorithm in the field? Recommended research publications? Is t...
I need to plot some data in various forms. Currently I'm using matplotlib and I'm fairly happy with the plots I'm able to produce. This question is on how to plot the last one. The data is similar to the "distance table", like this (just bigger, my table is 128x128 and still have 3 or more number per element) Now, my data is much bette...
