New page

General/'''Map2D''' is [[API]] to calculate the coordinates depending on 2D projection method of a sphere.

== constant ==

== struct ==
typedef float Map2DParaTypeReal;
typedef long Map2DParaTypeInteger;

== API ==
=== Calculation of coordinates by Projection Mode ===
Input: '''rotx''', '''roty''': Rotation angle, '''nx''', '''ny''': Divide number, '''mode''': Projection Mode<br>
Output: '''x''', '''y''': coordinates of image
extern void map2DCoordGet(Map2DParaTypeReal* x, Map2DParaTypeReal* y,
Map2DParaTypeReal rotx, Map2DParaTypeReal roty,
long nx, long ny, long mode);

<tr>
<th>mode</th>
<th>Projection Mode</th>
</tr>
<tr>
<td>0</td>
<td>Mercator</td>
</tr>
<tr>
<td>1</td>
<td>Mollweide</td>
</tr>
</table>
<br>

=== Calculation of number and delta angle for each latitude ===
Input: '''latitude''': Latitude, '''nparallel''': Divide number, '''mode''': Projection Mode<br>
Output: '''n''': Number of images to draw, '''d''': Delta of equator angle of images to draw
extern void map2DParallelInfo(Map2DParaTypeInteger* n,
Map2DParaTypeReal* d,
Map2DParaTypeReal latitude,
