Member Function Documentation
| int bvgl_triangle_interpolation_iterator< T >::endx | ( | ) | const [virtual] |
Returns ending x-value of the current scan line.
endx() should be larger than startx(), unless the scan line is empty
Implements vgl_region_scan_iterator.
Definition at line 79 of file bvgl_triangle_interpolation_iterator.txx.
| bool bvgl_triangle_interpolation_iterator< T >::next | ( | ) | [virtual] |
Tries to move to the next scan line.
Returns false if there are no more scan lines.
Implements vgl_region_scan_iterator.
Definition at line 56 of file bvgl_triangle_interpolation_iterator.txx.
| void bvgl_triangle_interpolation_iterator< T >::reset | ( | ) | [virtual] |
Resets the scan iterator to before the first scan line.
After calling this function, next() needs to be called before startx() and endx() form a valid scan line.
Implements vgl_region_scan_iterator.
Definition at line 48 of file bvgl_triangle_interpolation_iterator.txx.
| int bvgl_triangle_interpolation_iterator< T >::scany | ( | ) | const [virtual] |
y-coordinate of the current scan line.
Implements vgl_region_scan_iterator.
Definition at line 63 of file bvgl_triangle_interpolation_iterator.txx.
| int bvgl_triangle_interpolation_iterator< T >::startx | ( | ) | const [virtual] |
Returns starting x-value of the current scan line.
startx() should be smaller than endx(), unless the scan line is empty
Implements vgl_region_scan_iterator.
Definition at line 71 of file bvgl_triangle_interpolation_iterator.txx.
| T bvgl_triangle_interpolation_iterator< T >::value_at | ( | int | x | ) |
returns the interpolated value at location x in the current scanline.
Definition at line 87 of file bvgl_triangle_interpolation_iterator.txx.
