j'aimerais comprendre cette fonction plus precisement :

private int loadTexture(String path) {
 
		IntBuffer image = ByteBuffer.allocateDirect(4).order(
				ByteOrder.nativeOrder()).asIntBuffer();
		IL.ilGenImages(image);
		IL.ilBindImage(image.get(0));
		IL.ilLoadImage(path);
		IL.ilConvertImage(IL.IL_RGB, IL.IL_BYTE);
 
		ByteBuffer scratch = ByteBuffer.allocateDirect(IL
				.ilGetInteger(IL.IL_IMAGE_WIDTH)
				* IL.ilGetInteger(IL.IL_IMAGE_HEIGHT) * 3);
		IL.ilCopyPixels(0, 0, 0, IL.ilGetInteger(IL.IL_IMAGE_WIDTH), IL
				.ilGetInteger(IL.IL_IMAGE_HEIGHT), 1, IL.IL_RGB, IL.IL_BYTE,
				scratch);
 
		IntBuffer buf = ByteBuffer.allocateDirect(4).order(
				ByteOrder.nativeOrder()).asIntBuffer();
		GL11.glGenTextures(buf);
		GL11.glBindTexture(GL11.GL_TEXTURE_2D, buf.get(0));
		GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MIN_FILTER,
				GL11.GL_LINEAR);
		GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MAG_FILTER,
				GL11.GL_LINEAR);
		GL11.glTexImage2D(GL11.GL_TEXTURE_2D, 0, GL11.GL_RGB, IL
				.ilGetInteger(IL.IL_IMAGE_WIDTH), IL
				.ilGetInteger(IL.IL_IMAGE_HEIGHT), 0, IL.IL_RGB,
				IL.IL_UNSIGNED_BYTE, scratch);
 
		return buf.get(0);
