1.截止2024.4.27，根据vulkan.gpuinfo.org统计，只有9%的设备maxVertexInputAttributes为16，不存在低于16的设备。
|
||
9.0%的设备为28 - 31
|
||
70.7%的设备为32
|
||
9.6%的设备为64
|
||
|
||
由于我们暂时没有发现需要使用16个以上属性的情况，所以这里暂定使用16。
|
||
(如果时间过去久远，可再次查询此值是否可改成更高的值，以及是否需要)
|
||
|
||
2.为何va_name使用char[][]而不是String以及动态分配内存？
|
||
|
||
就是为了必避动态分配内存，以及可以直接memcpy处理，所以此处这样定义。
