Description

DBREND causes immediate mode rendering to begin.  When the workstation is in rendering mode, all of the structure element commands given to the PHIGS kernel are sent to the rendering workstation.  Rendering is a method of performing immediate mode processing in PHIGS.  It allows you to avoid creating structures.  Because it circumvents the structure hierarchy, it may sometimes be a faster method of generating output. One open workstation receives all of the output and continues to receive the output until you end rendering.  No structures can be open while rendering; however, you may execute structures in this mode by using the PEXST function. 

When the workstation is in rendering mode, all of the structure element commands issued to the PHIGS kernel are sent to the rendering workstation.  During rendering, PHIGS ignores both modification and deferral modes. 

Only one workstation can be rendering at one time.  If one workstation is rendering, and you try to begin rendering on a second one, PHIGS generates an error.
