I'm working on a graphics engine that lets you walk around a world that is made up of cubes (voxel engine) and I'm having some difficulties getting the results I want.
I'm not the best at 3D graphics, but I'm willing to learn. When I have anti-aliasing turned off, the textures lign up properly together on the surfaces, but when I turn it on, I see a lot of lines between each square face. I've taken a picture:
I've tried changing the mip map mag filter options on the sampler, but cannot get it to look right. I've tried increasing the quality of the textures, but that doesn't help either. When I use Linear TextureFilter but that just makes everything super blurry, and the edges are even more obvious. In fact many edges get some blurry white and dark color to them. Anisotropic doesn't help.
Nothing I do seems to get rid of those lines in between faces when I have AA turned on. Anyone have any advice on where I would start looking? I'm assuming it's because all of the faces are individual, and not mixed together when they are next to eachother. Not just the edges are being anti-aliased. Not sure if I'm even on the right track with that thought.
Any help would be appreciated. I'm using XNA 4.0 to do this.
