WebIntroduction to CUDA SDK 4.0 Web这两个API之间的区别在于坐标参数。绑定到线性内存的纹理只能在纹理坐标中寻址,因此text1Dfetch中的整数坐标参数,而数组同时支持纹理坐标和归一化坐标,因此tex1D中的浮点坐标参数。 当您分配单个浮点而不是浮点4时,我想您的数组没有正确对齐。
Web根据 CUDA programming reference guide您需要使用 tex1Dfetch()从绑定(bind)到线性纹理内存的一维纹理中读取,tex1D从绑定(bind)到 CUDA 数组的一维纹理中读取。 这适用于 CUDA 纹理引用和对象传递的 CUDA 纹理。 两个 API 之间的区别在于坐标参数。绑定(bind)到线性内存的纹理只能在纹理坐标中寻址(因此 text1Dfetch() 中 ...
