C++ (Cpp) tglFrustum Exemples

Exemple #1

Fichier : lolshielddemo.cpp Projet : 0xtob/lolshielddemo

void initGL()
{
  tglInit();
  tglViewport(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);

  tglMatrixMode(TGL_PROJECTION);
  float aspect = (float)SCREEN_HEIGHT / (float)SCREEN_WIDTH;
  tglFrustum(-1.0, 1.0, -aspect, aspect, 1.0, 5.0);
}

Exemple #2

Fichier : gfx_tinygl.cpp Projet : gmacon/residual

void GfxTinyGL::setupCamera(float fov, float nclip, float fclip, float roll) {
	tglMatrixMode(TGL_PROJECTION);
	tglLoadIdentity();

	float right = nclip * tan(fov / 2 * (LOCAL_PI / 180));
	tglFrustum(-right, right, -right * 0.75, right * 0.75, nclip, fclip);

	tglMatrixMode(TGL_MODELVIEW);
	tglLoadIdentity();

	tglRotatef(roll, 0, 0, -1);
}
