TITLE: Ipod in D Minor COUNTRY: Canada WEBPAGE: www.fitzel.ca/dart RENDERER USED: POV-Ray 3.6.1 (64bit) TOOLS USED: Wings 3D 0.98.32a, DAZ|Studio v1.3.0.1, PoseRay v3.8.18, Paint Shop Pro 8, Sanrope ColorPicker PRO 3 RENDER TIME: 6h35m HARDWARE USED: originally: P4 @ 3GHz (until the "thermal event" :-( ) later: AMD64 4800+ 3GB RAM :-) IMAGE DESCRIPTION: Victoria was thrilled to win two tickets to the symphony. Her boyfriend, Michael was not as excited. In the midst of the third movement, he decided he had had enough and decided to listen to something more his style. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: I decided early on to have a group of musicians playing together, but the setting eluded me. I started modelling instruments in Wings and experimented with the venue. I tried a concert in the park and one in the middle of a highway (called traffic jammin'), but I wasn't pleased with the composition. In the end, I turned to a formal stage and after a few weeks, came up with the idea of an audience member listening to his own music during a concert. There are multiple instances of 17 different human models in this scene: 3 violinists, 3 cellists, 3 trumpeters, 2 clarinetists, 1 flutist, 2 french hornists, 1 timpanist/conductor, and 2 audience members. All the humans were posed in DAZ|Studio, exported as OBJ and converted to mesh2 using PoseRay. One of the challenges in this scene was to make it fit into my computer's memory. Most of the human models memory requirements came from the high res (often 4000x4000) image_maps used to texture them (skin, eyes, hair, clothes). Each mesh2 instance would reallocate the image_map (even if it was used by another model). I used a number of "tricks" to reduce the memory: - Downsample the textures. - Replace the texture with a basic pigment (e.g., all the suits are simple rgb 0.1). - Share textures between models. - Make the left and right sides of a model different so that they appear to be different models when only one half is seen. For example, the conductor and timpanist are the same model. The black and white cellists are the same model - the left and right sides of the face are coloured differently. - Position the cloned models such that parts of them are obscured, making it harder to tell they are exact clones. (For example, the two flutists sitting next to each other). Optimizing the texture usage probably recovered about 40-50% of the memory. The final image still used up about 2.3GB of RAM! The stage floor is a little macro to draw random lengths of wood. The curtains are just a bunch of cones squished together. The risers and music stands are CSG based macros. The chairs are very basic CSG constructs. The spotlight beams are media filled cones.The included zip contains all the macros to recreate an empty stage. The human models are the free Michael and Victoria models available at DAZ (www.daz3d.com) - their clothing is also available from the DAZ on-line store. The violins, cellos, flutes, trumpets, clarinets, bassoon, and ipod are all Wings 3D models I made. The timpani (kettle drums), bass drum, and chimes are CSG.
