           Product: D
           Version: 1.00
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: digitalmars-com at baysmith.com


Jacco Bikker wrote several raytracing articles on DevMaster.net. I took his
third article and ported it to D. I was surprised to find that the D code is
slower than C++. After some help from people on the digitalmars.D.learn
newsgroup, my initial port was improved, but only to a point. The D code is
about 1.8 times slower than the C++ code. Hopefully, this example can be used
to find areas for improving the compiler.

Attachment to follow.
