. A vertex can be in some arbitrary format e.g. only a float3 position a float3 position float3 normal a float3 position float3.. be in some arbitrary format e.g. only a float3 position a float3 position float3 normal a float3 position float3 normal float2.. format e.g. only a float3 position a float3 position float3 normal a float3 position float3 normal float2 texcoord and so..
