Ortho camera clipping [SOLVED]

[Auradrummer]

Hello Masters,

I'm playing with a orthogonal camera using:

Code: Select all

ortho.buildProjectionMatrixOrthoLH( SCREEN_W * 4 * zoom, SCREEN_H * 4 * zoom, 20, 2000);
cam->setProjectionMatrix(ortho);

Is good, but when I move the camera and the mesh touches the border of the screen it is not rendered, simply disappear.
How can I solve this?

Thanks

Do you have a MCV (Minimal, Complete, Verifiable) example code? Those two lines of code seems to be good, depending on the context.

setProjectionMatrix has a default boolean parameter named "isOrthogonal" that is false, unless otherwise specified, meaning the provided projection matrix isn't orthogonal. If you are performing orthographic renderings you want to set that to "true", like this:

Code: Select all

cam->setProjectionMatrix(ortho,true);

Sorry for the delay in reply. Problem solved.

I made my mesh by loading a XML. So, the bounding box was constrained to the "start" of the mesh. As the clipping method is based in bounding boxes....

Thanks!
