CUDA 纹理对象是否支持 3 通道纹理？
Do CUDA texture object's support 3 channel textures?
旧的 texture references in CUDA only support 1, 2, and 4 channel textures (e.g., I would pad RGB colors to RGBA). Do the new CUDA texture object 支持 3 通道纹理吗？
（我目前无法访问较新的 nVidia 卡来试用它，文档开始让我的眼睛流血寻找答案）。
在适用于纹理引用和纹理对象的 texture memory 的一般描述中，它指出：
The texture object or the texture reference specifies:
...
The type of a texel, which is restricted to the basic integer and single-precision floating-point types and any of the 1-, 2-, and 4-component vector types defined in char, short, int, long, longlong, float, double that are derived from the basic integer and single-precision floating-point types.
所以，不，不支持 3 分量向量类型，即使是纹理对象也不支持。
