Add an xform that will reflect the image along the Y axis. This is accomplished by giving the xform a weight of one, color speed of 0 and a single linear variation with a weight of one. Its affine is centered on 0,0 with X at -1,0 and Y at 0,1.

Add an xform that will duplicate a rotated portion of the image along the Y axis. This is accomplished by giving the xform a weight of one, color speed of 0 and a single linear variation with a weight of one. Its affine is centered on 0,0 with X at -1,0 and Y at 0,-1.

Add two xforms, one for reflective symmetry and another for rotational symmetry.

Add a flatten variation to every xform where none of the following variations are present:

Pre Variations

pre_crop
pre_falloff2
pre_rotate_x
pre_rotate_y
pre_ztranslate

Variations

blur3D
bubble
bwraps
bwraps2
crop
cylinder
falloff2
hemisphere
julia3D
julia3Dz
linear3D
zblur
zcone
ztranslate

Post Variations

post_crop
post_falloff2
post_rotate_x
post_rotate_y

Variation Parameters

curl3D_cz

Note: This logic was taken from Apophysis.

Remove the flatten variation from all xforms.

Clear the current flame such that it only has one xform with no variations, pre and post affine transforms set to the identity matrix, and no xaos.

Re-render all previews.

Stop rendering previews.

Display the Final Render dialog. This will stop the render, and restart it from the beginning when the dialog is closed.

Display the Options dialog. This will stop the render, and restart it from the beginning if the dialog is closed with the OK button.
