Hi all!<br>
<br>
I used to set <span style=" color:#092e64;"><br>
camera</span>-><span style=" color:#00677c;">setProjectionMatrix</span>(<span
style=" color:#800080;">osg</span>::<span style=" color:#800080;">Matrix</span>::<span
style=" color:#00677c;">ortho2D</span>(<span style="
color:#000080;">0.0f</span>,<span style=" color:#c0c0c0;"> </span><span
style=" color:#000080;">1.0f</span>,<span style=" color:#c0c0c0;">
</span><span style=" color:#000080;">0.0f</span>,<span style="
color:#c0c0c0;"> </span><span style=" color:#000080;">1.0f</span>));<br>
when creating RTT-Cameras.<br>
<br>
In my SSAO-Module I need to retrieve the projection matrix but<br>
<span style=" color:#092e64;">if (cam</span>-><span style="
color:#00677c;">getProjectionMatrixAsOrtho</span>(<span style="
color:#092e64;">left</span>,<span style=" color:#c0c0c0;"> </span><span
style=" color:#092e64;">right</span>,<span style=" color:#c0c0c0;">
</span><span style=" color:#092e64;">bottom</span>,<span style="
color:#c0c0c0;"> </span><span style=" color:#092e64;">top</span>,<span
style=" color:#c0c0c0;"> </span><span style=" color:#092e64;">zNear</span>,<span
style=" color:#c0c0c0;"> </span><span style=" color:#092e64;">zFar</span>))
...<br>
seems to return true but the values retrieved look strange.<br>
<br>
So two questions:<br>
1) Do I have to assign osg::Matrix::ortho insted to RTT-Cameras?
What is the difference?<br>
2) Can I retrieve correct values when ortho2D is used?<br>
<br>
Many thanks for any assistance.<br>
