I am a professional developer working mostly with Java but on my spare time i like to play around with different languages and libraries. The thing is that i want to start learning how to develop 3D enabled applications or games. There are alot of engines out there but im afraid that by using those directly i will fail to learn the basic...
Are there huge differences in OpenGL 3.x vs 2.x? Is it waste of time learning OpenGL 2.x or are they both following the same concept? I think i read somewhere that 2.x was state based and that 3.x was not, is that correct? ...
We're doing some serious games interface work. Games allow unique new interfaces, but we also want to avoid having to reimplement traditional 2D controls, we want to leverage the years of refinement to windows controls. How would we go about hosting and rendering .NET controls in a '3D' context? 3D in the sense of, eventually they wil...
Hi, I've got a method that transforms a number of cylinders. If I run the method a second time it transforms the cylinders from their original position rather than their new position. Is there anyway of 'applying' the transformation so that it changes the underlying values of the cylinders so that I can re-transform from the new val...
I have a scene written in Java 3d, where the user's viewing position is set to some coordinate using the following code: ViewingPlatform vp = simpleUniverse.getViewingPlatform(); TransformGroup steerTG = vp.getViewPlatformTransform(); Transform3D t3d = new Transform3D(); steerTG.getTransform(t3d); t3d.lookAt( new Point3d(-5, 1...
I would like to write a library that draws some opengl on a given window handle. How can I initialize an opengl-context inside a given window? Is it possible to do that platform independent using SDL or some other library? ...
I want to calculate which face on a cube has been clicked. I've got the mouse to 3D down, and I can draw things, in 3D, at the mouse's position. All I need to do now is calculate WHAT face of a cube is being touched. EG. I have a function, when I pass the size, position and mouse position to it, it returns the face. Top, bottom, left, ...
Essentially, what I want to do (in DirectX) is to take two partially-transparent images and blend them together. This works fine with default blending, insofar as they both show up as overlapping, etc. However, the problem is that the opacity goes up markedly where the two intersect. This causes increasing problems as more sprites ove...
I'm having some serious trouble understanding the view matrix in XNA. I've come pretty far with all the other parts and since I've just learnt myself the required maths I don't want to use the built in Matrix-functions without understanding what they do first. Now I understand the basics of rotation, projection and translation but I can...
Hello, I obtained three dimensional data from my optical system in Visual C++.And I want to show this profiler on windows form application.Is there any special library you could advise to me?And How can I customize this library in Visual C++. Could you help me please? Yours Sincerely.... ...
i am looking for a 3D engine for developing a ruby game. i found some like G3Druby or ogrerb. which one is better to use and has better functionality? is there any other engine better than these? ...
Hello I got goal to achieve, 3d cube manipulated with mouse with gradient filling on each wall. I found some source codes coresponding to gradients and 3d rotating cube but here is the problem: When i put these two things together the effect looks like the cube was a wireframe with transparency to some gradient background hidden behind...
hey there! i have a 3D pointcloud and i'd like to efficiently query all points within distance d from an arbitrary point p (which is not necessarily part of the stored pointcloud) the querry would look something like Pointcloud getAllPoints(Point p, float d); what accelerationstructure would be appropriate for this? A range-tree see...
Hi, I would like to write a C# program that generates a 2D image from a rendered 3D object(s) by "slicing" the 3D object or through a cut-plane. The desired output of the 2D image should be data that can be displayed using a CAD. For example: A 3D image is defined by its vertices, these vertices is contained within Point3DList(). A meth...
How can I programmatically add 3-D shapes to Bing Maps (Virtual Earth)? ...
I'm developing a wxPython application. Will it be possible to embed a 3D animation controlled by Panda3D inside the gui? Bonus question: Do you think that Panda3D is the best choice? (My interest is physical simulations, and no, I don't need an engine that supports Physics, my program is responsible for calculating the physics, I just n...
I've been searching on Google for some C# programs. I have found Paint.NET. Is that the only C# program out there? What about games? Someone have a link to 3D game in C#? ...
I have two 2d circles in 3d space (defined by a center, normal, and radius) and I'm trying to come up with a pair of points that is one of the set of closest pairs of points. I know that there are anywhere from 1 to an infinite number of point pairs, I just need a single matching pair. Is there a simple way to do that? Precision is no...
i was learning 3d animation in wpf.. and most tutorials would make an image 3d then play with it alittle ..moving and changing dimensions.. so it got me wondering.. is it possible to add some type of data container (like a grid canvas.. or whatever).. and make it move in 3d dimensons too ? i am not talking about skewing.. i am talkin...
Is there a simple way of rendering to a BufferedImage in Java3D? I know you can extend Canvas3D, but it seems cumbersome if I just want to render directly. ...
