Clarke Steinback Ph.D. 3D Computer Modeling CSCI 140 Spring 2005 James Crossin

2005 Spring ->3D Computer Modeling ->Galleries ->James Crossin James Crossin   Final Scene   Whats Your Pleasure?   Inspiration My initially idea was to model the Lament Configuration or “puzzle box” from the Hellraiser movies.  Since that posed as a great challenge I chose to start with the attic scene from the first film and add the box once the room was complete.  Objects Room James Crossin   Framing James Crossin   Wood Braces James Crossin   Candle & Flame James Crossin Chair James Crossin   Mattress James Crossin Blood Puddles James Crossin   Lament Configuration James Crossin       Textures Wood Texture Google Image Search   Water Damage Procedural Texture   Blood Stains Procedural Texture   Wall Paper Google Image Search   Door Texture Google Image Search   Rust Texture Google Image Search   Brass Texture Procedural Texture Time Frame     Modeling Surfacing Room 1hr 15 mins 2 hr Framing 1 hr 1 hr Wood Braces 1hr 1hr Candle & Flame 30 min 30 min Chair 30 min 15 min Mattress 15 min 15 min Blood Puddles 1 hr 1hr Lament Configuration 2 hr 15 min Water Damage   2 hr Blood Stains   2 hr Volumetric Lighting   2 hr Render Time 17+ hrs per still! Problems and Solutions I experienced no problems with modeling as all the objects in the scene are basic.  The wood braces were time consuming as I had to copy, rotate and place 46 of them.  As was the modeling of the chains. The chain model is roughly 10’ in length and each link is made of two 24 sided, 12 segmented disc’s.  I completed the chain and later realized that I hadn’t reduced my polygons making manipulation of the objects and render time a severe headache.           Construction of the Lament Configuration was intimidating at first.  I had the larger shapes modeled but did have much more than two weeks left and had no idea how I was going to get all the finer details in.  I spoke to Clarke and he suggested I use a bump map of the box, which I eventually did. I also could eliminate the dark ring at the top of the candles.  I played with different modeling techniques, translucencies and even transparencies.  But I was only able to minimize it. Render time was my biggest foe.  I have 12 candles, each with a point light.  Originally I had a point and linear light on each candle for a whopping 24 lights.  Render time without any effects was around 15 mins.  I dropped the linear lights and halved my render time.  I played with different combinations of effects and found that radiosity and cuastics were the ones I wanted.  I applied 10-20% for both and a low anti-aliasing and came up with 17+ hr renders.  It was nerve racking.
