Hi,
I'm just starting play with 3D kind something:) I choose LWJGL.
1. How can I do function like fade to white and fade to black?
2. Is it complicate to draw 3D model?
3. Can I draw something in back screen? (like drawing, but not display)

1.
Set the opengl clear colour to black


start with a variable alpha= 1;
then every frame decrease alpha until it equals 0. (decrease it by 0.001 each frame)
set the colour using GL11.glColor4f(1,1,1,alpha); //r,g,b,a
Draw a rectangle over the whole screen, using the above colour.


2. WAY too complicated. Don't even try it at this stage. First try drawing textured squares and cubes, if you understand that, then maybe look at models.

3. I agree with sproingie.

Look at tutorials here: http://lwjgl.org/wiki/index.php?title=Main_Page for how to learn basic lwjgl.

3. LWJGL already double buffers for you so you needn't worry about that

Well. I'm making a JAVA remake of the game which was make in 90's. It has map in 2d, but models (even inv. in 3D)

I'm using orginal files for this game, so I need only render it:)

I will try, thanks:)

I think theagentd wanted to say that it's a no match, gameplay in 2D but suddenly everything has one more degree in inventory menu. A game will try to be totally 2D or 3D.

LWJGL doesn't really double buffer anything for you.

OpenGL has (almost always) two buffers: the buffer that is onscreen and the buffer that is not (backbuffer).

You always render to a buffer that is invisible, so there is no need to perform (manual) double buffering.

Yes. No. Maybe?

Google has step-by-step guides for everything, including self-teaching.

I use LWJGL to rasterize 2D projections of representations of virtual 3D objects, based on binary stored geometry and precise matrix transformations.

I will take it as my goal in life to translate and decipher that into wording comprehendable for mere mortals. Then I'm going to make a religion about it.

"I do things with stuff"

Well worded summary!
