Hi,
here is the textureLoader (I tried also the one from the Wiki but I get the same result):
public final static int loadTexture(String path) {
Image image = (new javax.swing.ImageIcon(Util.class.getResource(path))).getImage();
BufferedImage tex = new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_4BYTE_ABGR);
Graphics2D g = (Graphics2D) tex.getGraphics();
g.drawImage(image, null, null);
g.dispose();
// Put Image In Memory
ByteBuffer scratch = ByteBuffer.allocateDirect(4 * tex.getWidth() * tex.getHeight());
byte data[] = (byte[]) tex.getRaster().getDataElements(0, 0, tex.getWidth(), tex.getHeight(), null);
scratch.clear();
scratch.put(data);
scratch.rewind();
// Create A IntBuffer For Image Address In Memory
IntBuffer buf = ByteBuffer.allocateDirect(4).order(ByteOrder.nativeOrder()).asIntBuffer();
GL11.glGenTextures(buf); // Create Texture In OpenGL
GL11.glBindTexture(GL11.GL_TEXTURE_2D, buf.get(0));
// Typical Texture Generation Using Data From The Image
GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MIN_FILTER, GL11.GL_NEAREST);
GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MAG_FILTER, GL11.GL_NEAREST);
GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MAG_FILTER, GL11.GL_LINEAR);
GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MIN_FILTER, GL11.GL_LINEAR);
GL11.glTexImage2D(GL11.GL_TEXTURE_2D, 0, GL11.GL_RGBA, tex.getWidth(), tex.getHeight(), 0, GL11.GL_RGBA, GL11.GL_UNSIGNED_BYTE, scratch);
return buf.get(0); // Return Image Address In Memory
}
And here is the code rendering the quad:
GL11.glLoadIdentity();
GL11.glEnable(GL11.GL_TEXTURE_2D); // Enable Texture Mapping
GL11.glTranslatef(x,y,0);
GL11.glBindTexture(GL11.GL_TEXTURE_2D, texture);
GL11.glBegin(GL11.GL_QUADS);
GL11.glTexCoord2f(0.0f, 0.0f); GL11.glVertex2i(0,0);
GL11.glTexCoord2f(1.0f, 0.0f); GL11.glVertex2i(width,0);
GL11.glTexCoord2f(1.0f, 1.0f); GL11.glVertex2i(width,height);
GL11.glTexCoord2f(0.0f, 1.0f); GL11.glVertex2i(0,height);
GL11.glEnd();
and here is the what i do to initialize blending & alpha:
GL11.glEnable(GL11.GL_ALPHA_TEST);
GL11.glAlphaFunc(GL11.GL_GREATER, 0.0f);
GL11.glEnable(GL11.GL_BLEND);
GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
Thanks in advance,
Chris
