D3D12_BLEND_DESC

構造体
📘 Microsoft Learn (日本語) · English
サイズx64: 328 バイト / x86: 328 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)。

フィールド

フィールド型サイズx64x86説明
AlphaToCoverageEnableBOOL4+0+0アルファトゥカバレッジを有効にするか。MSAA時にアルファをカバレッジへ変換する。
IndependentBlendEnableBOOL4+4+4RT毎に独立したブレンド設定を使うか。FALSEならRenderTarget[0]を全RTに適用する。
RenderTargetD3D12_RENDER_TARGET_BLEND_DESC320+8+8各レンダーターゲットのブレンド設定配列。最大8要素を保持する。

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_BLEND_DESC サイズ: 328 バイト(x64)
dim st, 82    ; 4byte整数×82(構造体サイズ 328 / 4 切り上げ)
; AlphaToCoverageEnable : BOOL (+0, 4byte)  st.0 = 値  /  値 = st.0   (lpoke/lpeek も可)
; IndependentBlendEnable : BOOL (+4, 4byte)  st.1 = 値  /  値 = st.1   (lpoke/lpeek も可)
; RenderTarget : D3D12_RENDER_TARGET_BLEND_DESC (+8, 320byte)  varptr(st)+8 を基点に操作(320byte:入れ子/配列)
; ※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。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
