glReadBuffer 函数选择像素的颜色缓冲区源。语法C++ 复制 void WINAPI glReadBuffer( GLenum mode ); 参数mode 颜色缓冲区。 接受的值为 GL_FRONT_LEFT、GL_FRONT_RIGHT、GL_BACK_LEFT、GL_BACK_RIGHT、GL_FRONT、GL_BACK、GL_LEFT、GL_RIGHT 和 GL_AUX i,其中 i 介于0 到 GL_AUX_BUFFERS 1 之间。
glReadBuffer 函式會選取圖元的色彩緩衝區來源。 語法 C++ voidWINAPIglReadBuffer( GLenum mode ); 參數 mode 色彩緩衝區。 接受的值為 GL_FRONT_LEFT、GL_FRONT_RIGHT、GL_BACK_LEFT、GL_BACK_RIGHT、GL_FRONT、GL_BACK、GL_LEFT、GL_RIGHT 和 GL_AUXi,其中i介於 0 到 GL_AUX_BUFFERS 1 之間。
