サイズx64: 104 バイト / x86: 104 バイト

サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。

HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; D3D12_DISPATCH_RAYS_DESC サイズ: 104 バイト(x64)
dim st, 26    ; 4byte整数×26(構造体サイズ 104 / 4 切り上げ)
; RayGenerationShaderRecord : D3D12_GPU_VIRTUAL_ADDRESS_RANGE (+0, 16byte)  varptr(st)+0 を基点に操作(16byte:入れ子/配列)
; MissShaderTable : D3D12_GPU_VIRTUAL_ADDRESS_RANGE_AND_STRIDE (+16, 24byte)  varptr(st)+16 を基点に操作(24byte:入れ子/配列)
; HitGroupTable : D3D12_GPU_VIRTUAL_ADDRESS_RANGE_AND_STRIDE (+40, 24byte)  varptr(st)+40 を基点に操作(24byte:入れ子/配列)
; CallableShaderTable : D3D12_GPU_VIRTUAL_ADDRESS_RANGE_AND_STRIDE (+64, 24byte)  varptr(st)+64 を基点に操作(24byte:入れ子/配列)
; Width : DWORD (+88, 4byte)  st.22 = 値  /  値 = st.22   (lpoke/lpeek も可)

; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
