1// nx_pe_dll_d3d11draw.nx -- REAL GEOMETRY DRAW through the D3D11 API. Superset of d3d11ctx: device(43)+context(108) 2// vtables, 12 compiled methods. A foreign process via <d3d11.h>: create device -> GetImmediateContext -> CreateBuffer 3// (verts) [dev 3] -> CreateRenderTargetView [dev 9] -> OMSetRenderTargets [ctx 33] -> IASetVertexBuffers [ctx 18] -> 4// Draw(3,0) [ctx 13] -> the bound triangle is rasterized into the bound RT with barycentric per-vertex color interp 5// (the WARP-exact affine interp). Output graded vs knowledge/warp_gradient.ppm. Real geometry pipeline (verts from a real 6// bound VB) w/ fixed-function coloring (programmable VS/PS = the nx_dxbc_exec-caller-scratch rung).
