TITLE:High Speed Photography COUNTRY:USA WEBPAGE:None RENDERER USED:Povray v3.02 watcom.win32 pentium optimized TOOLS USED:Moray v3.01vc build 2483, PSP 3 for tga to jpg conversion RENDER TIME:20 houre 33 min 55 sec (not only process running) HARDWARE USED:PC 233 Mhz Pentium II 64 Mbytes memory, Win 95 IMAGE DESCRIPTION:A high speed rifle bullet "ruins" a glass made of glass. Just milliseconds after initial contact, the action is frozen by a strobe-flash just as cracks are propagating from the point of impact. For this competition, I took a different tack and modeled things that Moray/Povray do well -- metals, proceedural textures, and glass. I usually end up spending 80% of my time modelling and texturing and 20 % of my time in composition and lighting. This time I flipped the ratio and played a lot with various lighting schemes and odd things like focal blur (there's NO AA in this rendering -- all focal blur!) DESCRIPTION OF HOW THIS IMAGE WAS CREATED: Glass is a rotational spline in Moray. Walls are thin boxes, floor is a plane. Textures are highly modified Moray standard textures (Old glass and marble?). Three useful techniques worked out well for me. 1) Bullet motion blur is a scaled cylinder with a gradient pigment going from transparent to brass. 2) Cracks in glass are CSG'd with translational spline "cracks". 3) FINALLY got focal blur to work w/o totally cranking the image's gamma thru the roof (Yeah, I know this bug is fixed in the megapatch, but I started in this Povray version didn't want to change in mid-stream) JPG
