Parameters type Specifies the the data type of each coordinate in the array.
Description glNormalPointerEXT specifies the location and data format of an array of normals to use when rendering using the vertex array extension. Static elements may be modified by the application, but once they are modified, the application must explicitly respecify the array before using it for any rendering. When a normal array is specified, type , stride , count and pointer are saved as client-side state, and static array elements may be cached by the implementation. If enabled, the normal array is used when glDrawArraysEXT or glArrayElementEXT is called. Use glArrayElementEXT to specify primitives by indexing vertexes and vertex attributes.
