Well, I have to write a project with Java3D, but there are some unclearly things, for ex. I need to add (with the mouse) a new piece ( a new object ) to a created model ( in position (x,y,z) ). - How can the cursor coordinates be asked ? Or are there any other possibilities to solve this probl

[JAVA3D] Textures with Alpha values / png-format working with Java?

Re: [JAVA3D] Magician/Sorceress VS. JAVA 3D

[JAVA3D] gaussian splatting

I saw something similar done in VRML once. It was suppose to be a firefly. Thw woman who did it, ( I'd give her credit if I could remember her name) just used a few concentric spheres which were progressivly more transparent as the diameter increased. She ended up with a really nice effect. Hope

hum, I am not sure I agree with you for your expected behaviour: in fact I disagree ;-) Your view (key hole?) on the world changes but the world stays the same: a cube is a cube; what I would expect is either a scaling based on the available display space or, if no scaling, just a wider /smaller p
