In the attachment are three plotting issues that might be (partially) related.

 
Jagged shading     

Loss of color and incomplete clipping

The last one is the most severe because it takes color away when a plotobject is inside another object.

How can this be fixed? Explanations always welcome.

Looks like this

From: dsolve_numeric_output_with_extra_brackets.mw

which was derived from a 2d document where I removed all unnecessary overhead.

When the option output=listprocedure is removed, this extra argument is not shown any more.

With that extra argument substitution of a solution into the corresponding ode(s) is not possible.

Any idea why that is? How to avoid or remove it?

I currently have problems uploading

I want to display in 3d the following objects

• Animated plottools objects (e.g. a spinning cube)
• Static plot objects (e.g. surface plot)/li>
• Time dependent spacecurves (to trace the path of objects)

Technically I could

• create a sequence of time stamps
• generate for each time stamp a plot structure using plots:-display for all the above objects
• display the sequence of plot structures with plots:-display with the option insequence.

or

• create separate plots with plots:-animate for each time dependent object
• plot with plot3d all static objects
• display all plots with plots:-display

or

• defining a procedure containing all plotting commands as a function of time
• create a background plot of all static objects using plots:-display
• animate the procedure with a plots:-animate call with the background option

Without having any experience, my perference would be the last way. However I intend to generate some plot coordinates with dsolve,numeric. This would mean that at each point in time to be plotted, dsolve starts integration from the inital conditions (which I have not planned to update animation frame by animation frame)

Any recommensations or thoughts on this?

On some occasions I have seen output like this

where the user name is replaced by a placeholder.
How to achieve this?
