Public Member Functions | |
CustomVector (unsigned int starting_size=1024) | |
Constructor. | |
~CustomVector () | |
void | clear (unsigned int starting_size=1024) |
Clear clears all data and resizes. | |
void | resize (const unsigned int n) |
Resize Resize the data pointer using realloc In general you want to resize to a larger size. | |
void | push_back (const type &t) |
Push back a value Potentially resizes. | |
void | push_back_3 (const type *const p) |
Push back 3 values Potentially resizes. | |
void | mult3 (const type &v1, const type &v2, const type &v3) |
Multiply contiguous groups of 3 by different values. | |
unsigned int | elem () |
The number of elements, is the same as STL::vector size() Should be called size() but oh well. | |
type & | operator[] (const unsigned int idx) |
Operator[] - provide convenient set functionality (note NOT get). | |
type * | get_data () |
get the underlying data as a pointer objects | |
Private Attributes | |
type * | data |
The data pointer. | |
unsigned int | size |
The size of the associated memory block. | |
unsigned int | elements |
The number of stored elements. |
It has get_data() functionality, which gives direct access to the underlying data, which is necessary for handing OpenGL vertex and normal arrays - the native STL vector does not give straightforward access to the data pointers. This class also has a push_back_3 function which does a memcpy of 3 elements - this can be used instead of 3 push_back function calls. Although it wasn't rigorously tested it should save some time by virtue of less function calls. Although the savings may be trivial, I just haven't tested it.
This class was not written for general use because- it is designed specifically for use in conjunction with the MarchingCubes class only.
