の現在のコードを使用するonDrawFrame
と、エミュレーターには完璧に機能しますが、電話でSurfaceView
は空白で何も得られません。GLU.gluLookAt(); を使用する必要がある投稿を見つけました。gl.glLoadIdentity(); の代わりに それを行うと(onDrawFrameでコメントされているコード)、機能し、背景を取得しますが、電話でもエミュレーターでもテクスチャが読み込まれません。それらを読み込んでアプリを動作させるにはどうすればよいですか?
EDIT1:関数のGLU.gluPerspective(gl, 45.0f, (float)w / (float)h, 0.1f, 100.0f);
行にコメントを付けたonDrawFrame
ところ、テクスチャが表示されるようになりましたが、数秒後にプログラム強制が閉じます。
