I read your "Pointer basics" section and played around with pointers, references and arrays, and checked how they were stored in the memory. For about five minutes, I finished the implementation of my lookAt function, and it works great!

Thanks alot for your help!

In C it would be:

(Toggle Plain Text)

void fn(float* array, int length){
	int i;
	for(i=0;i<length;i++){
		// do something with the array
	}
}

void caller(void){
	float myarray[4]
	myarray[0] = 0.2;
	// etc
	fn(&myarray, 4);
}

It's not difficult in assembly.
