读取这两个buffer,是不是一读取,就是个128bit的值。与申请资源的时候,是FORMAT_FLOAT_4和FORMAT_INT_2等类型
没关系?也就是说,如果是int2的类型,读取一次,会将下一个int2的值也读取进来。
不像o1和i1等,会根据FORMAT_FLOAT_4和FORMAT_INT_2等类型,读取合适的位置?

这个问题中的gb和cb是指CAL的概念还是指SPL里面的GlobalBuffer对象和ConstBuffer对象?
如果是问CAL的概念,是这样的。
SPL中的ConstBuffer对象在CPU端有个缓存,会做data padding,把数据编排好以后再传送到GPU. GlobalBuffer对象暂时没有任何处理
