5f6937ca 2014-02-12 17:15:22 Align static and streaming vertex data to 16-byte boundaries. Certain vertex formats using fewer than 4 bytes could confuse our buffer code, giving us improperly aligned offsets. Aligning vertex data across the board should fix the problem, and minimal cost.

a5e44c92 2014-02-04 16:04:15 Relax alignment restrictions to allow more direct storage. Our restriction to 4-byte alignments caused us to always convert formats like R8 or R16, or R8G8 instead of allowing D3D to handle these formats naturally. From experimentation the proper rule seems to be "4-bytes, unless the vertex format is 1- or 2-byte size." I couldn't find supporting documentation on MSDN, but it seems common sense.

a5d67475 2014-02-04 16:04:13 Remove VertexBuffer::requiresConversion. Since we now have Renderer methods to query formats for vertex inputs, we can get rid of the remaining calls to VertexBuffer which we used to query properties of vertex formats.

a857c36b 2013-07-02 11:57:02 Refactor VertexAttribute to split the "current value" for generic attributes into its own class. VAOs in GLES 3 do not store the current values, so these must be handled separately from other Vertex Attribute data.
