Re: [JAVA3D] MIPMap

What a neat test!  Yes I think I can explain it.  Mipmapping is not an all or nothing technique.  When I first started working with textures I thought that a mipmap level was picked and used for the entire shape, but in fact that is not the case.  The mipmaps work at the texel level.  When a texel is going to be rendered Mipmapping uses a variety of techniques to determine what color to draw.  Across one shape being rendered you could concievably get a little piece of every mipmap level if it was a very near to a very far perspective. You can setup the algorithm for both minification and magnification.   Dave Yazel Cosm Development Team http://www.cosm-game.com/     ----- Original Message ----- From: Alex Terrazas To: [EMAIL PROTECTED] Sent: Sunday, March 18, 2001 9:29 AM Subject: [JAVA3D] MIPMap Hey- I am working on an example of MIPMapping.  I generate a series of BufferedImages each with Text indicating the image size (e.g. 256 x 256, 128 x 128 ...1 x 1). If the viewer is on the size of the box and goes forward and backward, the MIPMap works as expected and changes BufferedImages as expect. When I rotate the textured box, however, I get situations where part of one BufferedImage overlays part of the other.  As you move forward or backward, the texture "wipe" across. I have included a screen shot.  256 and 128 are combined. Anyway, does anyone know why this happens? Thanks- Alex
