Re: Program is terribly slow



I get about 43 fps with a 7800GS.

Well thats more than 1.9, but for "simple" sphere mapping, this
looks kind of slow to me.

The only lines I changed are the ones with "m_ShpereMapping". What can
it be that makes it so slow!?

# # #
if(m_LightsOn || m_SphereMapping)
{
glEnableClientState(GL_NORMAL_ARRAY);
glNormalPointer(GL_FLOAT, sizeof(POLY_NODE),
BUFFER_OFFSET(((BYTE*)&tNodes_all->normal)));
}

if(m_SphereMapping)
{
glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_SPHERE_MAP);
glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_SPHERE_MAP);
glEnable(GL_TEXTURE_GEN_S); glEnable(GL_TEXTURE_GEN_T);
}

glDrawArrays(GL_TRIANGLES, 0, the_obj.m_tri_animation.Size());


if(m_SphereMapping)
{
glDisable(GL_TEXTURE_GEN_S); glDisable(GL_TEXTURE_GEN_T);
}
