grasoff.net,


I added all libraries in Java NetBeans Project Properties -> Add Jar file -> libs (mine). I have just done like you said, but error is just the same.

Blazkowicz,

С этим все получилось, а теперь выпадает вот такая ошибка

Blazkowicz,

Я понимаю, но ошибку нет.

Blazkowicz,

Вы можете сказать, почему у меня не показывается текстура? Ошибок больше нет.

Blazkowicz,

Но если бы он не видел image, то сказал, что его нет, но я его закинула туда, где он будет его видеть, но текстура не грузится

Blazkowicz,
Можете ссылку какую-нибудь сбросить с примерами работы с текстурой и картинками?

Blazkowicz,

Спасибо.

Привет, всем. Кстати, я нашла свою ошибку:
строку ap.setTexture(texture) поменяйте на строку
ap.setTexture(loader.getTexture()) и все сработает.

Здравствуйте всем.
Подскажите, пожлуйста, где можно скачать бесплатно кгиги по Java 3D графике для начинающих. Скиньте ссылку, если можно.
Спасибо всем

Доброго времени суток, всем.

Подключила библиотеку к проекту, которую скачала. Но у меня выходят ошибки.
Посмотрите, пожалуйста, мой проект
