i got a problem with my textures in a JOGL program. the textures i draw onto a cube which is taken from a displaylist are flickering. here is a video which shows the problem: http://www.youtube.com/watch?v=nIj3b_Rs7Nw (sorry for the bad video, i don't know what went wrong at the beginning) first i thought it would be an anti-alising problem, but i used smoother textures and the problem remains. then i enabled mipmapping on the textures, but with no luck. the result is always the same.
here is the code i first used to get textures ready. this is without mipmapping.
final int[] tmp = new int[1];
gl.glGenTextures(1, tmp, 0);
id = tmp[0];
BufferedImage bufferedImage = null;
int width = 0;
int height = 0;
try {
bufferedImage = ImageIO.read(new File(filename));
width = bufferedImage.getWidth();
height = bufferedImage.getHeight();
}
catch (IOException e) {
e.printStackTrace();
}
WritableRaster raster = Raster.createInterleavedRaster(DataBuffer.TYPE_BYTE, width, height, 4, null);
ComponentColorModel colorModel = new ComponentColorModel(ColorSpace.getInstance(ColorSpace.CS_sRGB), new int[] {
8, 8, 8, 8 }, true, false, ComponentColorModel.TRANSLUCENT, DataBuffer.TYPE_BYTE);
BufferedImage dukeImg = new BufferedImage(colorModel, raster, false, null);
Graphics2D g = dukeImg.createGraphics();
g.drawImage(bufferedImage, null, null);
DataBufferByte dukeBuf = (DataBufferByte) raster.getDataBuffer();
byte[] dukeRGBA = dukeBuf.getData();
ByteBuffer bb = ByteBuffer.wrap(dukeRGBA);
bb.position(0);
bb.mark();
gl.glBindTexture(GL2.GL_TEXTURE_2D, id);
gl.glPixelStorei(GL2.GL_UNPACK_ALIGNMENT, 1);
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_WRAP_S, GL2.GL_REPEAT);
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_WRAP_T, GL2.GL_REPEAT);
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_MAG_FILTER, GL2.GL_NEAREST);
gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_MIN_FILTER, GL2.GL_NEAREST);
gl.glTexEnvf(GL2.GL_TEXTURE_ENV, GL2.GL_TEXTURE_ENV_MODE, GL2.GL_REPLACE);
gl.glTexImage2D(GL2.GL_TEXTURE_2D, 0, GL2.GL_RGBA, width, height, 0, GL2.GL_RGBA, GL2.GL_UNSIGNED_BYTE, bb);
...
gl.glBindTexture(GL2.GL_TEXTURE_2D, id);
then i decided to use the build in JOGL texture class. the setTexParameteri()
calls i took fro开发者_StackOverflowm this post JOGL mipmaps and texture shimmering , but they didn't solved the problem.
try {
TextureData textureData = TextureIO.newTextureData(drawable.getGLProfile(), new File(
"data/images/Kachel1.png"), true, TextureIO.PNG);
Texture tile = TextureIO.newTexture(textureData);
tile.setTexParameteri(GL2.GL_TEXTURE_WRAP_S, GL2.GL_REPEAT);
tile.setTexParameteri(GL2.GL_TEXTURE_WRAP_T, GL2.GL_REPEAT);
tile.setTexParameteri(GL2.GL_TEXTURE_MAG_FILTER, GL2.GL_NEAREST);
tile.setTexParameteri(GL2.GL_TEXTURE_MIN_FILTER, GL2.GL_LINEAR_MIPMAP_LINEAR);
gl.glGenerateMipmap(GL2.GL_TEXTURE_2D);
}
catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
so now i don't know what to do to get rid of the flickering. any suggestions?
