This doesn’t work:

#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.

It would be nice to be able to specify colors in HLS as well as RGB.

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.

When you press alt+b or access the “about” dialog in the Help menu it displays some text including software version number and list of contributors.

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.

On Windows, when I try and save a file while it is being parsed prior to rendering, I get an error, “Failed to save file: The operation completed successfully”, with a single OK button to click. Despite the weird wording, I’m OK with that.

However after clicking OK I get the error, “Failed to save file ‘...’“, with three buttons: Cancel, Try Again, Continue. Not sure what “Continue” means in this context, given that the possibilities would seem to be covered by the other two buttons. Whatever.

Also, sometimes I get a message with only a single “Retry” button. Not sure what the exact message was.

Anyway, the real problem is that, regardless of which button I press, the program continues to spawning the same error message endlessly. Luckily there is a delay between them, but still it would be nice to have at least one of the three buttons *stop* POV-Ray from asking me again.

Also, once the program finishes parsing the file and it becomes possible once again to save the file, it does nothing. I.e. it doesn’t save the file. So what’s the point of the message and all the options? Why not just say, “Unable to save the file, file is parsing” and be done with it?

I think I recall the same behavior in 3.6.2, so it’s nothing new that’s been introduced.

In other languages if you encounter an error you’ll often be presented with a stack trace showing not only the file and line number the error occurred at, but also any calling functions and _their_ calling functions and so on.

Currently, Povray reports the line number of the error as well as the last five or so lines prior to the error. This is usually OK in simple scenes, but breaks down when you start making use of inclusion and macros.

Let’s say you have a macro located in a file that you then include in your scene. Within your scene you call the macro multiple times, passing input to it. However, by accident you pass _invalid_ input to the macro at some point, resulting in an error when parsing. In this case Povray will report the error as belonging to the macro whereas the actual bug exists in the calling code. If the macro is called more than once in your scene it can be difficult to figure out _which_ instance is the one supplying the bad input.

Not sure how much of this is achievable in Povray.

Would be great to have a “Reload” option in the File menu to manually reload the current file from disk, discarding all subsequent changes since the last save.

Would be great if there were a “Rename” option in the editor File menu to rename the current file name. Otherwise, you have to close the file, rename it in file manager, then open the file again, thus loosing the current tab position and undo history for the file.

Someone built a version of Povray with internal support for automatic subdivision of meshes. See:

http://www.cise.ufl.edu/~xwu/Pov-Sub/

Would like to see this feature added natively to Povray.

See Notepad++ or EditPad Lite for examples.

It would be nice to be able to drag tabs in the editor window to change their order, so as to group opened files together by relevance for instance.

Currently, array items may only be referenced by their index number (an integer). It would be nice to also be able to assign string values as array indexes, as in other scripting languages.

Currently, arrays are of a fixed size. You can’t add or remove items to/from an array. I think it would like arrays to be expandable with no fixed and pre-determined size.
