The intended use is to make it large and far away from the camera, so that it is always behind all the terrain and objects in the world. It also contains an image of the Sun (as a texture billboard). The Sun is moved and sky is colored appropriately for the time of day (set with SetTime). It also supplies a real Light (<a class="el" href="classvtLight.html">vtLight</a>) which approximates the actual color, direction and intensity of sunlight. <p><table border="0" cellpadding="0" cellspacing="0"><tr><td></td></tr><tr><td colspan="2"><br><h2>Public Member Functions</h2></td></tr><tr><td class="memItemLeft" nowrap align="right" valign="top">void </td><td class="memItemRight" valign="bottom"><a class="el" href="classvtSkyDome.html#ec10223de676b595a235037c67e9d99e">Create</a> (const char *starfile, int depth, float radius, const char *sun_texture=<a class="elRef" doxygen="vtdata.tag:../vtdata/" href="../vtdata/MathTypes_8h.html#6c3e226b4d4795d518ab341b0824ec29">NULL</a>, const char *moon_texture=<a class="elRef" doxygen="vtdata.tag:../vtdata/" href="../vtdata/MathTypes_8h.html#6c3e226b4d4795d518ab341b0824ec29">NULL</a>)</td></tr><tr><td class="memItemLeft" nowrap align="right" valign="top">void </td><td class="memItemRight" valign="bottom"><a class="el" href="classvtSkyDome.html#f9315604a2d55bf133d15a90fafef759">SetTime</a> (const <a class="elRef" doxygen="vtdata.tag:../vtdata/" href="../vtdata/classvtTime.html">vtTime</a> &time)</td></tr></table><hr><h2>Member Function Documentation</h2><a class="anchor" name="ec10223de676b595a235037c67e9d99e"></a><!-- doxytag: member="vtSkyDome::Create" ref="ec10223de676b595a235037c67e9d99e" args="(const char *starfile, int depth, float radius, const char *sun_texture=NULL, const char *moon_texture=NULL)" --><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">void vtSkyDome::Create </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top">const char * </td> <td class="mdname" nowrap> <em>starfile</em>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>int </td> <td class="mdname" nowrap> <em>depth</em>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>float </td> <td class="mdname" nowrap> <em>radius</em>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>const char * </td> <td class="mdname" nowrap> <em>sun_texture</em> = <code><a class="elRef" doxygen="vtdata.tag:../vtdata/" href="../vtdata/MathTypes_8h.html#6c3e226b4d4795d518ab341b0824ec29">NULL</a></code>, </td> </tr> <tr> <td class="md" nowrap align="right"></td> <td class="md"></td> <td class="md" nowrap>const char * </td> <td class="mdname" nowrap> <em>moon_texture</em> = <code><a class="elRef" doxygen="vtdata.tag:../vtdata/" href="../vtdata/MathTypes_8h.html#6c3e226b4d4795d518ab341b0824ec29">NULL</a></code></td> </tr> <tr> <td class="md"></td> <td class="md">) </td> <td class="md" colspan="2"></td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p>Creates a complete SkyDome, which includes a StarDome. </td> </tr></table><a class="anchor" name="f9315604a2d55bf133d15a90fafef759"></a><!-- doxytag: member="vtSkyDome::SetTime" ref="f9315604a2d55bf133d15a90fafef759" args="(const vtTime &time)" --><p><table class="mdTable" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top">void vtSkyDome::SetTime </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top">const <a class="elRef" doxygen="vtdata.tag:../vtdata/" href="../vtdata/classvtTime.html">vtTime</a> & </td> <td class="mdname1" valign="top" nowrap> <em>time</em> </td> <td class="md" valign="top"> ) </td> <td class="md" nowrap></td> </tr> </table> </td> </tr></table><table cellspacing="5" cellpadding="0" border="0"> <tr> <td> </td> <td><p>Sets the time of day (or night). <dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td valign="top"></td><td valign="top"><em>time</em> </td><td>Time in seconds since midnight. </td></tr> </table></dl> </td> </tr></table><hr size="1"><address style="align: right;"><small>Generated on Mon Jan 14 14:41:01 2008 for vtlib library by <a href="http://www.doxygen.org/index.html"><img src="doxygen.png" alt="doxygen" align="middle" border="0"></a> 1.4.5 </small></address></body></html>⌨️ 快捷键说明
