WinAPI + Direct3D
14.08.2020, 22:39. Показов 350. Ответов 0
Доброго времени суток!
Осваиваю Direct3D по учебнику и столкнулся с проблемой (что не редкость,учитывая количество опечаток и ошибок в учебнике)
В результате работы кода, должен отрисоваться вращающийся куб, но вместо куба я получаю неопределённую фигуру из хаотически расположенных треугольников
Урок касался буфера индексов, учебник "Горнаков С.Г. DirectX 9 уроки программирования на С++"
