f71513cab5 Rewrote the handling of AutoTransform::setAutoScaleToScreen(bool) functionality so that is disabling CullingActive when switched on. 2018-04-02 18:29:39 +01:00

92092a56ae Refactored AutoTransform so that it dynamically computes the rotation, scale and matrices during the cull traversal to enable usage in multi-view, multi-threaded applications 2017-04-26 11:50:35 +01:00

752a5e2a3c From Javier Taibo, "ere is the new code with Billboard "rotate around axis" functionality. 
A new AutoRotateMode was added. I named it ROTATE_TO_AXIS to be
consistent with the other AutoRotateModes, even though it changes from
how is called in Billboard (AXIAL_ROT).

  Setters and getters for rotation axis and normal were also added to the
AutoTransform class interface.

  The implementation is mainly a copy-paste from Billboard code.

1d1dcf2cf3 To osg::AutoTransform added support for MinimumScale, MaximumScale and AutoScaleTransitionWidth parameters 
and a new scheme for computing the scaling when using autoscale that introduces smooth
transitions to the scaling of the subgraph so that it looks more natural.

7a7c197af3 Added minimum and maximum scale support to osg::AutoTransform 2008-03-17 15:22:03 +00:00

c58221ddae Added _firstTimeToInitEyePoint = true to the setAutoRotateMode to force the AutoTransform 
to recompute its position on next frame.

1c6e165cb3 From Farshid Lashkari, "The setScale(Vec3) method of osg::AutoTransform does not dirty the 
matrix. The fix is attached."

25abad8307 From Paul Martz, "I've attempted to make AutoTransform override computeBounds() to return 
an invalid bounding sphere if it hasn't seen a cull traversal yet. It
depends on _firstTimeToSetEyePoint, which is initially true, then false
after a cull. There might be a better way? If so, let me know.

This change does resolve the issue I had encountered with auto scale to
screen and incorrect culling."

ca61c11134 From David Fries, "I added code to also check the local up vector, but 
only if one of the rotation modes is selected, because autoscale isn't
affected by the camera rotations. "

3579506fa8 Added support for osg::AutoTransform::setAutoRotateMode(AutoRotateMode) deprecating 
the previous setAutoRotateToScreen().  Added support for ROTATE_TO_CAMERA mode.

Cleaned up the autotransform demo to use a sensible number of labels

895a722842 Addd support for maximum screen text size into osgText when auto scale to 
screen is active.

Added osgautotransform demo.

a703130aa0 Have taken a few more steps towards support for view dependant transformations 
by adding a ComputeTransformCallback to osg::Transform, and have now removed
the recently added AutoTransform since it is nolonger required.  Have also
updated CullVisitor to account for the new ways for tracking transformation
matrices in the scene.
