What kind of phone? Apple, Android?

If the SDK is open-source, then you probably don't have to pay for it.
If the SDK is proprietary, then they might charge a fee.

It sounds interesting. But, if I was going to develop drone apps, I would first take a look at the market for them, and see if it's worthwhile. Anything that is wasted time is wasted money, in my opinion.

In Topic: Apple developer forums gone to pot

I haven't noticed it at all. I have always thought the forums were user-to-user. The iOS Developer Program offers paid technical support if you really need it.

In Topic: GLSL halfvector?

>>It does not matter wheather the light is directional or not.

Half vector is L+V. Are you saying Lpoint+V = Ldir+V? That doesn't make sense. They're two different light vectors.

I guess I have to debug it to know for sure. Perhaps this will help write out a vector.

gl_FragColor = vec4( gl_LightSource[0].halfVector.xyz, 1.0 );

I'm learning old GLSL so I can support old OpenGL code. I have no plans to update anytime soon.
I just would like to know if gl_LightSource[0].halfVector.xyz is the same value as my calculated one.
I'm using directional lights.
