# instructions: This makefile can be used to compile and render using
# BMRT, Houdini (not render), and 3Delight.
#   make vex -- compile using vcc (Houdini)
#   make delight -- compile using shaderdl (3Delight)
#   make bmrt -- compile using slc (BMRT)
#   make render_delight -- renders scene files using renderdl (3Delight)
#   make render_bmrt -- renders scene files using rendrib (BMRT)
#   make install_houdini -- copies surface and displacement shaders to
#           proper places in the directory defined by HOUDINI_BASE. You still
#           need to change SHOPsurface and SHOPdisplace to refer to the shaders
#   make depend -- make dependencies for these shaders
#   make clean -- remove compiled files and Emacs temporary files
#
