difference between modelview projection matrix and texture

Answer 1

Re: Difference between Modelview matrix and projection matrix

ModelView matrix is the concatenation of Model matrix and View Matrix. View Matrix defines the position(location and orientation) of the camera, while model matrix defines the frame's position of the primitives you are going to draw. 
Projection matrix defines the characteristics of your camera, such as clip planes, field of view, projection method etc.
