resource limits of DrawIndexedInstanced()

Recommended Posts

from the directx 10 docs, Resource Limits:

 

 

DrawIndexed[Instanced]() vertex count (incl. instancing) 232

 

just what do they mean by this?

 

the original mesh (vb) can only have 232 vertices? IE its the limit for IndexCountPerInstance?

 

or you can only create 232 instances of a mesh (vb) with one call  (InstanceCount limit) ?

 

or ALL the meshes (original + created) can only have a total of 232 vertices?  this i would find hard to believe.

My guess would be that the documentation is broken, and it should say 232

"Aw, wadda you know from funny?"

 

Note that the quote above got nuked too, it should be 2^32, not 232.

 

IE: two raised to the thirty second power.

 

so the total number of vertices including instancing is 2^32.

 

i would assume that means the limit for:

IndexCountPerInstance * InstanceCount = total instanced verts

is 2^32.
