More on textures

[K.I.L.E.R]

When I load my texture using NEHE's texture loader it looks fine but when I do it my way it looks like a whole bunch of red, green and blue pixels fudged all over.

My guess is that my code (below) doesn't get the appropriate colour values?

Or is it something else?

(In C++, reading a file like I have works fine, why not in Java? Assuming the problem is that I'm reading the file)

public final static int loadTextureMod(String path)
	{
		ImageIcon imgIc = new ImageIcon(path);
		Image img = (Image)imgIc.getImage();

		BufferedImage bImg = new BufferedImage
		(
			img.getWidth(null),
			img.getHeight(null),
			BufferedImage.TYPE_3BYTE_BGR
		);

		final int fileSize = bImg.getHeight() * bImg.getWidth() * 4;

		FileReader fr;
		int[] tmpBuff = new int[fileSize];
		int i = 0;

		try
		{
			fr = new FileReader(path);

			while((tmpBuff[i] = fr.read()) != -1)
			{
				i++;
			}
		}
		catch (Exception e)
		{
			System.out.println(e.getMessage());
		}

		IntBuffer buf = BufferUtils.createIntBuffer(fileSize);
		buf.rewind();

		GL11.glGenTextures(buf); // Create Texture In OpenGL

		GL11.glBindTexture(GL11.GL_TEXTURE_2D, buf.get(0));
		// Typical Texture Generation Using Data From The Image

		// Linear Filtering
		GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MIN_FILTER, GL11.GL_LINEAR);
		// Linear Filtering
		GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MAG_FILTER, GL11.GL_LINEAR);

		// Generate The Texture
		GL11.glTexImage2D
		(
			GL11.GL_TEXTURE_2D,
			0,
			GL11.GL_RGB,
			bImg.getWidth(),
			bImg.getHeight(),
			0, GL11.GL_RGB,
			GL11.GL_UNSIGNED_BYTE,
			buf
		);

		return buf.get(0);
	}

That's coz you've specified a GL_RGB image when you have 4 bytes in your source image (GL_RGBA)...

I've fixed it.

A 24bit bitmap graphic has values of:
R8, G8, B8 and A0 = 3 colour channels * 8bits = 24bits per pixel + 0 alpha.

I've fixed my code to reflect that, however it still doesn't work properly.

Now the box has red stripes all over it instead of a pixel mess of RGB. :lol:

What else could be wrong?

I think you've got your buffers mixed up.  You're generating a huge number of texture object names in buf, when you only want one.  You're then uploading those names to the GL as an image.
