1  Game Development / Game Mechanics / Perspective Transformation on: 2010-12-22 02:53:33
I want to tilt part of my game display like this:

After searching the web it looks like I need a PerspectiveTransformation:

However, its not clear to me if this is overkill or what I need to do this in real time, JAI sounds like its just for images, I want to be laying down more dynamic images. Any previous experience in this regard is appreciated.

NM. Just found it, have to set translations on graphics object, not on a transform as setTransform() wipes any other transformations.

This is generally working, but I'm having trouble using Graphics properly it appears.

I create a top-level graphics object thusly:
Graphics t1 = g.create(3,25);

and then in a method later...
Graphics t2 = t1.create(0,0,800,600)

I think the problem comes when I create an AffineTransform with another translation and set that on the graphics object:

This works except for the detail of forgetting the first translation it appears, how do I preserve the first, w/o knowing the values? I know I could pass them around, but seems like I'm missing something in the API.

I think you indicate how with the width and height being specified so it should just rotate that area not against the whole screen. Ill give that a try anyway.

The problem is I don't see how to make that transformation. For instance if I want to draw component "as is" in the top half of screen, that's fine but what's the transformation so that drawing will be mirrored in the bottom half of screen? It seems like it mirror on the dimensions of the screen, not just the bottom half of the screen.

I have a game that has two portions which should logically use the same rendering logic, except the data is different for each and the location (translation) and perspective (mirror image) are different.

Should I use a image to render these to, and then blit to the main backscreen, using a transformation, or is there something more logical I should do to get them to draw directly to the backscreen?
