[Scilab-users] hist3d() puzzling rendering

[Rafael Guerra]

Hi,


Preserving the color of the original hidden faces under interactive rotations, does not seem to be a bad idea. It allows assessing what parts of the objects are hidden under the original choice of view angles.

The behaviour of plot3d is similar.


Regards,

Rafael

Hello,

Using hist3d() -- just enter hist3d() to plot the example --, and rotating the figure in 3D (right-press and drag), we can note that the color of the different faces are not the same: 2 of the four faces are rendered with the hidden color (usually used for the internal or back faces), and the 2 other ones with the default or chosen color and color mode.

I was deeming that the usage of the hidden color for 2 over 4 apparent faces is a bug<http://bugzilla.scilab.org/show_bug.cgi?id=15458>.

Now, i am wondering if it is not rather intentional, in order to have a kind of lighting effect.

I still think that, even if it was intentional, it should rather be fixed. Now, Scilab has some explicit lighting features.

But, before possibly processing the bug report, what's your opinion?

Samuel
