working through some training tutorials about using high dynamic
range (HDR) images with Maya lighting and mental ray rendering techniques
purchased a £10 20cm "gazing ball" from a local
dynamic range imagery is used to help embed the cg elements into
the scene with location-specific lighting, provides reflections
and gets the CG elements a step closer to looking photoreal.
this shot I wanted to stay in Maya and practice render layers without
taking all the separate elements into an external compositing package.
useBackground shader captures the shadows on the floor and lower
portion of the couch.
camera projection of the original plate onto simple geometry is
used to generate the reflections of the floor, couch, and items
on the shelf in background.
original plate is also projected onto some cylinder geometry for
the tripod legs in the foreground to allow a little box to sit
behind the tripod in real 3D space.
