so how then are none of the faces on the green rock not receiving light , in a similar vein to the springboards tip.
The left and top sides of the green rock is getting direct sun light, don't you see it? ???

Just to confirm that this OP anomaly is not a "lens flare" sort of thing, I have looked for, and found, another Rover Curiosity photo of it.
That was the first thing I did, but when I saw the low quality of that photo I ignored it. It looks like that feature is relatively far away from the camera, as it appears too small on both photos, specially in the one from the camera with shorter focal length (the left camera).

QuoteAn additional reason for our pretty much knowing this "white object" is not simply a ray of sunlight on the surface is, even if it were a "break of a shadow", we should still see very specific sunlight/shadow lines there on the ground - just as we see in other instances of sunlight/shadow presentations.
I don't understand what you mean by "sunlight/shadow lines", could you explain it? Thanks in advance. :)

QuotePlus still, the double-sided nearest end of this anomaly, that we can clearly see in the posted prior photos, confirms this to be a 3D object, and not a shadow break.
As I said before (and as I tried to show with my 3D sketch that turned out to be just a waste of time), I think the double-sided end is a real 3D object (most likely a rock, or maybe two), jutting out of the sand.

I should have thought of this in the beginning. :)

I used this site to see where the camera was pointing to when the photo was taken, to see if that area could appear in another photo, and, as seen in this page, it's pointing to an area the rover already traversed.

Knowing this, I searched for the sol in which the rover was on that area or near it, and found a sol with several photos, sol 1110. Looking through the photos on that sol I found a photo of the area from the OP photo, this one.

Any questions? :)

"Any questions? :)"

No, no questions right now! However, I do have suspect about some of the considerable "differences" in these two photos. Even some of the rocks are shown very differently in the two pics - almost as if someone has purposely messed with the photo where the anomaly is not there. I do have a major reason for one of the differences that would make it impossible for the white anomaly to appear as it does in the other (original) pic . Will address that tomorrow afternoon. :)

not a waste of time for you , how much did you learn ?.. o ,when doing Boolean operations , make sure your mindfull of your operands. what's cutting what , what's merging and what's being discarded :D

yes , but the comparative was

Quotein a similar vein to the springboards tip.

none of the faces on the green rock , that are parallel with the tip , are lit

looks like you got to the tip of this one :D  a quirk of light and shadows , intermingled with a few broken pieces of Stratified's
that second picture can be so useful at times

but then like in times of spokey thing , they just add more to the mystery

good shot matey

Not much, most of the time was spent trying to learn how to use Blender's strange user interface. :)

I'm used to Boolean operations, only in code, as I work as a programmer. :)
