NV2A Draw methods - JayFoxRox/xqemu-jfr GitHub Wiki

All of these are between NV097_SET_BEGIN_END with BEGIN(primitive type) and END

Examples: Present() [?] in D3D (Not sure which version) = used for final blit

Format set by setter functions? What if the format changes halfway through?
Set data using either NV097_SET_VERTEX4F, NV097_SET_NORMAL3F, ... or NV097_SET_VERTEX_DATA*
Next vertex selected using NV097_SET_VERTEX4F and probably [but not confirmed] NV097_SET_VERTEX* in general
This has states, so setting diffuse one will mean it will stick for the next vertices until it's set again. This means we either must copy from the previous state OR keep track of the current state

Examples: Present() [?] in D3D (Not sure which version) = used for final blit

Not indexed, duplicate vertices will be reuploaded
Data uploaded using NV097_INLINE_ARRAY
Uses attribute format from NV097_SET_VERTEX_DATA_ARRAY_FORMAT
Stride and attribute offset is generated by stride = offset(i) += attribute->size(i-1) * attribute->count(i-1)
It is unknown wether an attribute->stride != 0 is respected.

Uses vertex buffer from NV097_SET_VERTEX_DATA_ARRAY_OFFSET
Uses attribute format from NV097_SET_VERTEX_DATA_ARRAY_FORMAT
Maximum of 256 vertices per draw call
Maximum number of addressable vertices 0xffff (index_of_first_vertex <= 0xffff; (index_of_first_vertex + vertex_count) <= 0xffff)
2 Arguments: Number of vertices, Index of first Vertex
