Object display in coordinates

Hi everyone, I want to display an object.The camlight function was used to display the object, but the result is not what I want. The picture on the left(first picture) is the result I get with this function, the picture on the right(second picture) is the result I want.Does anyone know what function or method to use?

Don't use the camlight function...

Thanks!But I have found how to solve this problem.It only needs to lower the specular highlighting. camlight; material('dull');
