Re: [JAVA3D] I know you know what I do not know

I think you want to display the grayscale image in 3D. Then you have to create the 3D geometry for the 2D-image. You can interpret the gray values of the 2D-image as z-Values in the third dimension. To rotate the scene you have to add a MouseRotateBehavior to your scene. Fei Li wrote: Hi, My fir

[JAVA3D] "java HelloJava3Da" and display mode?

Dear friends, I tried to install java3d into win2000, which is based on linux using VMWARE. I can run "javac HelloJava3Da.java" and produce HelloJava3Da.class. If I copy this HelloJava3Da.class into my old computer in which java3d was already installed, "java HelloJava3Da" can work very

Re: [JAVA3D] generate sweep surface

I guess you have to develop this for yourself. Java3D does not support the usage of splines for the generation of surfaces. Am I right, that you want to use arbitrary curves/paths to calculate the surface? Then it gets quite complicated to find a fitting solution because you have to specify some co

Re: [JAVA3D] "java HelloJava3Da" and display mode?

Hi, I don't know so much about VMWARE, but from what you have described, it's a sort of win2000 emulator on top of whatever linux distribution you have. So exactly that's your problem: java3d needs a real 3D graphics device, not an emulated one (if there is any !!!). Question: why don't you run y

Nope. If you look at the stack trace, you see that the exception was thrown after trying to figure out a GraphicsConfiguration. i.e., the following code returns null : GraphicsConfigTemplate3D template3d = new GraphicsConfigTemplate3D(); return GraphicsEnvironment.getLocalGraphi

[JAVA3D] substracting shapes

Hi all, I have been reading about Jun and I did  have a look to the source and it's very heavy for my purposes.  I just have some quite simple shape classes created by me and I would like to be able to create one of them and substract from it another one at their intersection points. Maybe so

Re: [JAVA3D] substracting shapes

If you wish to do it yourself: - triangulate the faces of the two shapes - intersect the edges of one with the triangles of the other - and vice versa - remember per triangle the point(s) introduced by the piercing edges of the other surface - combine these points with the original points of the t

Re: [JAVA3D] I know you know what I do not know

You can also have a DOT3 BumpMapping. The grayscale images is actually a heigh map field, and is converted to a normal map. NomalMap DOT3 LightMap = per pixel BumpMap But to have it you must have a 3D hardware with Combine DOT3 capabilities (GForce, Radeon, etc) see a running demo here (source c

Are you referring to a 2D screen view coordinate being converted to 3D? Without more information you can't simply convert them...you'd need some idea of the rotation of the point in the 3D and some other references. I don't see how else you could do thatI could be wrong though.   Here i

Re: [JAVA3D] Convert from 2D coordinate to 3D Coordinate

Sorry if I miss the point, but... What about z = f(x,y) or (x,y,f(x,y)) ? where f is a function wich will calculate in Z using x and y values. A classic one: f(x,y) = sin(x) + sin(y) This can be fine to generate simple terrain surfaces. f(a,r) can can also be a polar function, where x,y are
