not sure if this is the right place to ask, but i have made a certain simulation with JavaFX 3D API and it's working very well so far,
now i wanted to implement 3D shadows and i wasn't able to find any articles or help, i had to read a lot of articles about 3D shadow mapping algorithms but i wasn't able to apply anything on my JavaFX project
i already assumed that it's impossible but if anyone of you have tried that, let me know

yes, it's because of the limitations, however that seems like a fair explanation, i will check again and report back.
thank you

I'm looking at the Oracle docs for JavaFX 3D, but I cannot find any indication that it supports custom shaders, or anything else that could be used to create proper shadows in any way I know of. ( It barely supports anything useful according to the docs, it looks like Oracle abandoned it astonishingly quickly. ) In the longterm switching to another graphics library could be a good idea, if the project let's that.

Edit: I thought about it a bit more, the API supports custom triangle meshes, so that could be used to create late '90s style hacked shadows. Basically you define a plane which would "receive" shadows, then take all the meshes that cast shadows on that plane, and flatten them against that plane (project them onto it) into a new mesh, and add those back into the JavaFX scenegraph with a black color, and proper positioning. On the other hand, I wouldn't recommend doing this, it's more like a thought experiment.

JavaFX is not abandoned. Also there is no such thing as JavaFX 3D, but if you do a Google search it might seem otherwise because of pages named such as 'JavaFX 3D rotations' which just means 3D rotations in JavaFX.

You are right, I ment the 3D related classes/packages got abandoned quickly. Although by looking at how Oracle treats JavaFX, I wouldn't count on it having a bright future, if I remember correctly they either already cut it out of JDK, or they plan to do it in a future release. 

that's what i thought,thank you guys for your replies and suggestions, i think i should just get over it and start with openGL. ThinMatrix already seems like a good choice to start with, thanks again
