lwjgl

I would like to create a window such that there is no "black background" area, but instead you see through to any other windows that are open, etc. That is, render the scene and only the scene, leaving no frame and no background area. I've read about a method that involves rendering to a hidden OpenGL window and buffering it in memory, creating a transparent layered window, and copying from memory to the transparent window. Obviously this is very cpu/memory intensive, so I was wondering if there was any better ways of doing it, within Java and LWJGL? karlphillip This is something that can only

I've been working with lwjgl for some time, and recently I've decided to switch from fixed function pipeline to shaders. So, the first thing when I'm starting my program, I set the ContextAttrib(3, 2) so I will be using GL 3.2+. The problem is that when I switch on higher version of GL a lot of functions become unsupported. Before switching to higher GL, I've used Slick's font (TrueTypeFont) to render the text I needed, but now the drawString method of TrueTypeFont has an unsupported function within itself. I've tried to google for solution, but nothing came up. Does anyone know if it is

I've been delving into game programming with Slick2D, and I've began to wonder if in the long run, knowing LWJGL would be more helpful. On one hand, Slick2D is fast and simple, but it seems LWJGL is more adaptable in the sense that it has both 2D and 3D capabilities. For someone who is intermediate in java, and wants to make games, would it be worth the additional effort to learn LWJGL right off the bat? I don't think the two are really related. I mean, I know Slick is built on top of LWGJL, but that's not what I'm getting at here. Slick exists to take advantage of the hardware graphics and

I followed a tutorial for reading a picture and creating a texture out of it, however, it shows up flipped upside down when rendered. The image is power of two. Main class public class Main { public static void main(String args[]) throws IOException{ Main quadExample = new Main(); quadExample.start(); } public void start() throws IOException { try { Display.setDisplayMode(new DisplayMode(1280,720)); Display.create(); } catch (LWJGLException e) { e.printStackTrace(); System.exit(0); } // init OpenGL GL11.glMatrixMode(GL11.GL_PROJECTION); GL11.glLoadIdentity(); GL11.glOrtho(0, 1280, 0, 720, -1,

So I nearly implemented a free-flight camera using vectors and something like gluLookAt. The movement in all 4 directions and rotation around the Y-axis work fine. For the rotation around the Y-axis I calculate the vector between the eye and center vector and then rotate it with the rotation matrix like this: Vector temp = vecmath.vector(center.x() - eye.x(), center.y() - eye.y(), center.z() - eye.z()); float vecX = (temp.x()*(float) Math.cos(-turnSpeed)) + (temp.z()* (float)Math.sin(-turnSpeed)); float vecY = temp.y(); float vecZ = (temp.x()*(float) -Math.sin(-turnSpeed))+ (temp.z()*(float

So i've been wondering how to change the openGL version in lwjgl.. I know i can change the version with PixelFormat and ContextAttribs as being said on the wiki http://lwjgl.org/wiki/index.php?title=Version_selection But that only can take me down to 3.2 minimum what if i want to take it even lower? like maybe 2.1 or even 1.1? Is there any way to do this? Well, the logic behind OpenGL context versions can be a bit confusing. But it does make sense when seeing it in the historical context: Back in the day, there were no special "context version" hints. There was just one way to create a context
