296Geometric PrimitivesDefinite Bug3.70 RC7DeferMediummax gradient computation is not thread safe (isosurface...Tracked on GitHub
3.71 release Task Description

It appears as a side effect of investigation of #294: the code in isosurf.cpp, inside
bool IsoSurface::Function_Find_Root_R(ISO_ThreadData& itd, const ISO_Pair* EP1, const ISO_Pair* EP2, DBL dt, DBL t21, DBL len, DBL& maxg)

	if(gradient < temp)
		gradient = temp;

is not thread-safe (The code is used at render time, there is a data race between < and = operation, as gradient is stored in the global object and accessed in write mode by the cited code)

It is only important if the gradient is initially undervaluated (otherwise, all is fine, no write-access)

300OtherFeature Request3.70 RC7DeferVery LowReference Documentation SupportTracked on GitHub
Task Description

As emerged as an idea during the discussion of FS#299, an SDL / POV-Ray editor feature would be useful that allows API documentation via formal comments, e.g. in include files:

 * Creates a car object.
 * @param a
 *        description of param a
 * ...
#macro car(a,b,c)

In addition to the ability of (auto-)generating a documentation file from such comments, an editor window feature would be convenient that allows popup display of a macro’s (object’s / parameter’s / ...) documentation section.

303OtherDefinite Bug3.70 RC7DeferVery Lowwrong bit depth reported for OpenEXR file formatTracked on GitHub
Task Description

When using OpenEXR output file format, POV-Ray erroneously reports it as “24 bpp EXR” in the message output, while in fact it generates a 3×16 = 48 bpp file.
