超级模糊的纹理 - XNA [英] Super blurry textures - XNA

问题描述

当我近距离观察我的纹理时，我的纹理似乎变得非常模糊.我正在创建一个类似我的世界的地形东西，我希望纹理被像素化 - 就像它是制作的而不是 XNA 尝试为我平滑它.

I seem to be getting really blurry textures when I look at my textures up close. I am creating a minecraft-like terrain thing and I would like the textures to be pixelated - like it is made rather than XNA try to smooth it out for me.

它的显示方式如下:http:///s1100.photobucket.com/albums/g420/darestium/?action=view&current=bluryminecraftterrain.png

如有任何建议，我们将不胜感激.

Any suggestions would be much appeciated.

推荐答案

它与抗锯齿无关...它与硬件如何对纹理中的纹素进行采样有关.XNA 中的默认过滤器通常是线性的，但要获得那些看起来块状"的纹理，您必须使用 Point.

It's not related to anti-aliasing... it's related to how the hardware samples the texels in the texture. The default filter in XNA is usually Linear, but to get those "blocky" looking textures you must use Point.

在 C# 中，您可以将任何 SamplerStates 设置为使用 PointWrap.这是点过滤与 UV 环绕的组合.

In C# you can set any of your SamplerStates to use PointWrap. This is a combination of point filtering with UV wrapping.

// any state index from 0 to 15, textures usually take 0 first    
GraphicsDevice.SamplerStates[0] = SamplerState.PointWrap; 

然而，它必须分配给与 SamplerState 相同的寄存器.例如.寄存器 s0 通常是 SamplerStates[0].或者，您可以在着色器上强制执行采样器状态，并在那里设置您的寄存器:

However it must the one assigned to the same register as the SamplerState. eg. register s0 will usually be SamplerStates[0]. Alternatively you can enforce sampler states on the shader, and set your registers there:

sampler2D textureSampler : register(s0) = sampler_state
{
    Texture = <Texture>;
    MipFilter = Point;
    MagFilter = Point;
    MinFilter = Point;
    AddressU = Wrap;
    AddressV = Wrap;
};

您也可以将 MipFilter 设置为 None 强制关闭 mipmapping.

You can also force mipmapping off with MipFilter set to None.
