.materialファイルの覚書

①ユニフォーム変数への値の受け渡し定義（デフォルト抜粋)

　u_worldViewProjectionMatrix = WORLD_VIEW_PROJECTION_MATRIX　sampler u_diffuseTexture　u_ambientColor = 0.6, 0.6, 0.6 u_cameraPosition = CAMERA_WORLD_POSITION u_inverseTransposeWorldViewMatrix = INVERSE_TRANSPOSE_WORLD_VIEW_MATRIX u_specularExponent = 1

②techniqueのdefine部分

　technique { pass { defines = DIRECTIONAL_LIGHT_COUNT 1;BILL_Y 1;BILL_X 1　←ユーザー定義を使用したい場合には「定義名値」を「;」セミコロンで区切る } }

　シェーダー側では、

　#if defined(BILL_Y) && (BILL_X)　←定義名が有効かどうか判断するﾌﾟﾘｺﾝﾊﾟｲﾙ　　～～プログラム　#endif
