texture filter

OpenGL OpenGL: Basic Coding

Hi,

if I don’t use gluBuild2DMipmaps to generate mipmaps for opengl( I simply load a single texture using glTexImage2D), how does opengl deal with the texture if I moving it far and far?

Thanks

OpenGL, will simply apply this version of your texture.
That means that your textured object won’t look as good if it’s small on your screen as it could if you were using gluBuildMipmaps, especially there can be some sort of texture flickering. The second disadvantage is that OpenGL can’t access a smaller texture if object small on screen and therefore can’t save bandwidth.
I’d strongly recommend using MipMaps, It needs only 33% more storage space for very size and your app will be much faster!
