[Rd] persp - incorrect shading of triangular facets (PR#4731)
Full_Name: Ross Ihaka Version: all versions containing persp OS: linux Submission from: (NULL) (130.216.191.167) When is persp is invoked on a matrix of heights which contains missing values, the surface which is drawn will contain triangular facets. The shading computations for these facets are incorrect and always produce black facets. (I plan to fix this - the report is just in case I forget or get hit by a bus).
