Solved it!!!!
This code seems to get the bottom line of a 3d object, and get its Y coord
on the backbuffer:D
SimpleVector vec,objcenter;
float[] boundingvec;
boundingvec = obj.getMesh().getBoundingBox();
objcenter = obj.getTransformedCenter();
vec = new SimpleVector(
0, boundingvec[3], boundingvec[4]);
vec.matMul(obj.getWorldTransformation());
theY = Interact2D.project3D2D(world.getCamera(),buffer,vec).y;
Egon, is there any ways to increase the quality of my rendered images?
Is there any antialiasing, or, well, anything that can improve the accuracy
of my models at such a close up view?
Perhaps I should render large, and use the highly powerful java2d functions to resize the buffered image.
EDIT: Yup! Resizing with java2d is DEFINATELY the way to go!:)
Any other tips are welcomed!
