FS#335: macro works in variable but not in array Mike H Sat, 06 Feb 2016 02:01:05 +0000
#declare pavement_object = array[2]
{
object {trash_can_macro() scale 3/4 translate -x * 1/2},
object {potted_plant_macro(_CT_rand2) scale 3/4 scale 3/2 translate -x * 1/2}
}

This does work:

#declare trash_can_object = object {trash_can_macro()};
#declare potted_plant_object = object {potted_plant_macro(_CT_rand2)};
#declare pavement_object = array[2]
{
object {trash_can_object scale 3/4 translate -x * 1/2},
object {potted_plant_object scale 3/4 scale 3/2 translate -x * 1/2}
}

Logically, I cannot see a reason for this to be so.]]>

FS#334: HLS colors Mike H Sat, 23 Jan 2016 00:21:39 +0000
Currently, you can use a macor to convert individual colors. But this does not work in color_maps where you want smooth gradations/interpolations between two or several colors.]]>

FS#333: Make text in "about" alt+b dialog selectable with the mouse and copy-able Mike H Mon, 18 Jan 2016 00:23:15 +0000
It would be nice to be able to select and copy this text using this mouse. Sometimes in the newsgroup I have to tell people what version of POVray I am using, and typing the version number can be a pain.]]>

FS#332: Progress animation in taskbar tabs Mike H Fri, 15 Jan 2016 07:00:42 +0000
Here is an example of Chrome downloading something and showing the progress in the taskbar:

Here is an example with Paint.NET instead:

I think this feature would use fewer CPU resources than a) minimizing/maximizing the whole application window each time you want to check progress, or b) hovering the mouse over the taskbar button to show the thumbnails.]]>

FS#331: Intersection causes quadric to disappear Richard Callwood III Mon, 27 Jul 2015 22:50:56 +0000
intersection
{ quadric { , , , -1 }
cylinder { 0, y, 1 }
}

However, when I extend the clipping cylinder downward:

intersection
{ quadric { , , , -1 }
cylinder { -y, y, 1 }
}

the object disappears completely in POV-Ray 3.7 and 3.7.1. In POV-Ray
3.6.1, it renders as expected.

POV-Ray 3.7.0.unofficial (self-compiled with g++ 4.8, but completely unaltered)
POV-Ray 3.7.1-alpha.8150025.unofficial
openSUSE 13.2 GNU/Linux

This scene file illustrates the problem:

// +w480 +h240
#version 3.6; //[sic]

global_settings { assumed_gamma 1 }

camera
{ location
look_at
right 2 * x

light_source

}

box

}

plane

pigment { checker rgb 0.05 rgb 1 }
}

intersection

cylinder { 0, y, 1 }
pigment { green 0.5 }
translate
}

intersection
{ quadric { , , , -1 }
cylinder { -y, y, 1 }
pigment { green 0.5 }
translate
}

On the right side, there should have been a cylinder capped with a paraboloid. A [[http://news.povray.org/povray.bugreports/thread/%3C55b39c37%241%40news.povray.org%3E/|thread has been started in povray.bugreports]]. Jerome has started to look at it.

FS#329: Mesh_camera type 0 output seems Manson Fri, 12 Jun 2015 10:37:22 +0000
The first line of the mesh output seems to be repeated resulting in incorrect light colour values.

If the first line of the texture is skipped then the values seem to be correct.]]>

FS#328: Ascii char '=' in filenames causes command line parsing failure Marco Costa Wed, 04 Mar 2015 19:41:59 +0000 povray +OqXfFbD0Vg5XjZgi5sOefkvdF_oCGrZ1ChVhrQw==.png +IqXfFbD0Vg5XjZgi5sOefkvdF_oCGrZ1ChVhrQw==.pov +W1000 +H1000

The following command succeeds:
povray +OqXfFbD0Vg5XjZgi5sOefkvdF_oCGrZ1ChVhrQw.png +IqXfFbD0Vg5XjZgi5sOefkvdF_oCGrZ1ChVhrQw.pov +W1000 +H1000


Any option that gets a filename as parameter will fail if it contains '='.

It is a regression, as it worked fine with 3.6.]]>
