I have seen done with midp1.0 3d games.
now studying how this is achieved.

ask you experts, to the point A?
or leave a qq, msn study together A

there is a simple 3D engine. There are some practical information.

order on the phone using j2me achieve 3D,
first is to have a filled polygon and polygon drawing functions.
nokia phones have similar functions. But here there is a controversy with drawPolygong or use drawpixs to achieve. And there is a special online polygon drawing engine, you can look on Squawk on the nokia.

followed to achieve their float, trigonometric functions, color transformation. That is, to mimic the use int.

then is the establishment of three-dimensional coordinates of the model
implement various algorithms such as projectors, coordinate transformation, lighting effects.
course, z-buf and so on.

j2me itself but because of some of the characteristics of the various algorithms can only be simple to achieve.
such as Atomic 3D Engine to achieve the following functions:
- multiple objects simultaneously on screen
- real-time backface culling
- real-time z sorting
- flat light shading
- independent cameras (every object has its own camera)
- solid-wireframe switch control
- frame rate tester

welcome to study together.

To be honest, j2me achieve 3D To the extent practical, we can say almost impossible.
because the polygon fill material in j2me difficult to achieve, even if achieved, the speed is not up to the practical requirements.
but to achieve some simple functions, to learn 3d programming, very well and I was with this idea before study reported on j2me 3d.
on the phone now wants to achieve true 3d or use c / c + +.
principles used in this regard and I said above, or almost. Squawk on the nokia's article stresses the principles in this regard.

are engaged based midp1.0 of 3d, can work together to look qq: 68200389

now it seems this little ahead, but soon realized the smooth the. In fact, the sun j2se do 3d very good, if the hardware arrives, then, sun is not stupid enough to allow other companies to create a standard level. Therefore, to achieve the algorithm is not important, the key is now the time had not yet come

upcoming November of the "programmer" magazine in presentations, to buy time to see it.

do it with 2.0, features some strong

midp1.0 difficult to achieve.

difficult, not as good as the pictures do the 3D effect, switch it well, a bit difficult to achieve on the phone. Written using j2me program up and running are common slow Yeah, not to mention the 3D yet.

Mobile 3D Graphics API/JSR184
so it

Mobile 3D Graphics API/JSR184
has come out, some companies have were using,
but do not know why, do not download.

And now in j2me achieve some simple 3d games such as car racing.
can say that is not really 3d games, it uses the method to simulate the texture do.
truly done using j2me 3d game I've seen only two little
First 3d maze game,
Another is on.
are very simple.

course, with c / c + + to write, there are some very good 3D games, such as coredisgn do games.

has now made a number of things about the polygon turning, for maps, I think in terms of speed j2me now seems difficult to achieve

This is a simple, using Atomic 3D ; Engine developed
3D Sokoban game Demo.

Well, thank you.
now doing these things.
have done some if walked, run away, turned around, etc. Camera effect of change.
Some drawLine generally no problem.
fillRect if so, to draw a quadrilateral, then because there is no direct function Midp1.0.
drawLine does not know to write, or use fillRect to write.
another map, I really have no idea that I do not know how to do.
threefootcat (Sanjiaomao) seems very experience, I hope exhibitions.
hope you will continue to speak a lot
