[osg-users] reflection on mesh texture

[Vinicius Nonnenmacher]

Hi,

I am trying to understand what are these 'wavy' effect. It changes depending on the camera position. Is it my texture that is beeing replicated for every triangle on the terrain mesh ? or the material attached to it ?




Thank you!

Cheers,
Vinicius

Hi Vinicius, I think it is a texture repeating pattern. If you want to
avoid this effect, look for "seamless texture patterns" and programs to
do it (for example, the "texturize" plugin for GIMP).

Vinicius,

That looks like texture aliasing. Enable mipmapping by setting a
minification filter like so:

texture->setFilter(osg::Texture::MIN_FILTER,
osg::Texture::LINEAR_MIPMAP_LINEAR);
texture->setFilter(osg::Texture::MAG_FILTER, osg::Texture::LINEAR);

Good luck.
