1  Java Game APIs & Engines / Java 3D / problem of projection on: 2002-11-13 12:49:52
hi,

I have points in a virtual world.
All points are in a same plan (Z = cste)


I used canvas3D.getPixelLocationFromImagePlate(coord3D,coord2D)
to find the position of a point in image plate.

How can I found 3D position of an image plate point. if I use
canvas3D.getPixelLocationInImagePlate(coord2D,coord3D)
the point isn't in z =cste plan but in z = 0 plan.


in fact, I search a matrix to project points between 2 plans
(in my case plan z=0 in plan z=cste)



Point (x,y,z =cste )----- getPixelLocationFromImagePlate ---> Point(x',y',0)


Point(x',y',0)     ------- Huh ------->(x,y,z=cste)



Thanks,
David.
2  Java Game APIs & Engines / Java 3D / display axes with java3d on: 2002-11-04 07:13:09
Hello,

I want to display a 2d curve y = f(x) with java3d.
Exist there objects of Java3D API to display the axes (with the graduations) X and Y?

^

Is there possible to increase the curve without touching with the axes?

I will appreciate if you can provide a little code.

Thanks in advance.
David.
