public Color GetPixelBilinear(float u, float v, float w, int mipLevel)

Parameters

u

float
The u coordinate of the pixel to get.

v

float
The v coordinate of the pixel to get.

w

float
The w coordinate of the pixel to get.

mipLevel

int
The mipmap level to read from. The range is 
0
through the texture's Texture.mipmapCount. The default value is 
0
.

Returns

Type

Description

ColorThe pixel color.

Remarks

This method gets pixel data from the texture in CPU memory. Texture.isReadable must be 
true
.
Unity uses bilinear filtering to return the pixel color.
The lower left corner is (0, 0, 0). If the pixel coordinate is outside the texture's dimensions, Unity clamps or repeats it, depending on the texture's TextureWrapMode.
You can't use 
GetPixelBilinear
with textures that use Crunch texture compression. Use Texture3D.GetPixels32 instead.
