WebJan 6, 2024 · To create a vertex buffer that cannot contain clip flags, include the D3DUSAGE_DONOTCLIP flag for the Usage parameter. The D3DUSAGE_DONOTCLIP flag is applied only if you also indicate that the vertex buffer will contain transformed vertices - the D3DFVF_XYZRHW flag is included in the FVF parameter. As a general rule, do not hold a lock across more than one frame. When working with vertex buffers, you are allowed to make multiple lock calls; however, you must ensure that the number of lock calls match the number of unlock calls. DrawPrimitive calls will not succeed with any outstanding lock count on any … See more [in] OffsetToLock Type: UINT Offset into the vertex data to lock, in bytes.
