Re: [JAVA3D] Trans3D (get)lookAt ?

try this: - first create a direction vector (for example 0, 0, -1). - get the Transform3D. - invert the Transform3D. - use Transform3D.transform(vector) - the resulting vector should point in the right direction. This should also work with a point. Hope this helps, Chris Sterling Wright wrote:

Hello folks, I would like to know how one can assign a font extrusion to a Font3D. This fontExtrusion must be the depth of a text, say you want to have a Text3D caption with a depth 2, how can this be achieved ? Thanxx, Marcel Koonen ==

After several days, with no experience in tracking, I was able to start using the bird driver from NCSA. I was able to get 2 birds to work with my NT machine, but the performance seemed to become a problem when I added the input from a another device and the mouse. Let me know your questions. A

[JAVA3D] Directional Light

Hi, Can anyone say if anythng changed with DirectionalLight between the last beta of J3D 1.2 and the final ship code ? With the last beta, parts of my objects that were at different angles to the directional light were nicely coming out with different brightnesses, but now everything seems to co

[JAVA3D] Mixing 2D and 3D

I would like to display messages as text on top of my Canvas3D. I'm using the retained mode instead of the pure-immediate mode. I'm trying to use the getGraphics2D method from Java 3D 1.2, but I have no idea how to use it. I tried overriding paint and updating the 2D graphics there, but I've ha

Hello Jack, happy finding somebody who know something about bird. I work on a PC under Window 98. I have one bird connected on port COM1 of this PC. What I would like is to collect data from the bird, i.e. the 3D coordinates of the prob. I attach on this mail my test file and the porperties file w

Re: [JAVA3D] Mixing 2D and 3D

Somewhere along the way you should be overriding the postRender() or postSwap() function of Canvas3D; inside these function is where you should do your drawing from my understanding. The thing I'm not sure of is whether the things you draw will go into the back buffer... I would think so, in whic

[JAVA3D] Cafe and Java3d

I've been using cafe pretty successfully to develop a gui for my 3d project. I used to be able to make a stand-alone jar file using the deploy feature, but now that I've upgraded to java1.3 and java3d 1.2, the jar file seems to be missing some classes (Quat4d, Point4f, PlatformGeometry...). The o

[JAVA3D] hemisphere

Hi, I am new to Java 3D and probably my question is very simple. I know that there is a Sphere class in the utils package, but I don't know how to create a hemisphere. My project requires rendering of multiple hemispheres that are painted partly or completely on top of each other. Please give me

Re: [JAVA3D] hemisphere

Well, if you are going to make lots of them, I'd suggest a custom built model of a hemisphere. There is no innate hemisphere geometry. Attached it an example 3DS hemisphere courtesy of 3DS Max 2.5 You can use the ncsa packages to import it. If licensing is a worry, convert one to the format inclu

Re: [JAVA3D] Sphere

Create a transform group, and set the transform of that to the required translation. Add the shape to the TransformGroup, then the TransformGroup to the BranchGroup [or other higher level Node]. Second step is to read the tutorial and go through the examples. It is fairly clear and well written.
