ON SCULPTED PRIMITIVES

In Second life objects are created by

combining a set of types of

primitives. Among them the newest

and most different from the others isits nature and behavior is the

sculpted primitive. Sculpted

primitives are generated by deriving

the colour values present in a special

type of texture: the sculpted texture.

Those values correspond to a xyz

coordinate point in space. Sculpted

prims allows the creation of organic

shapes using a single primitive

instead of several and thus loweringthe bandwidth necessary to render

it. On the other side, a sculpted prim

takes longer to get fully rendered,

requires specialized third party

software for its creation, and does

not behave physically according to its

final shape but instead as either a

sphere or a plane.

DAZ3D Hexagon 2.5 offers out-of-the-box support for Second Life

sculpty creations. This was used to create several experimental sculpties used in the early experimental

simulations and ultimately used to model the “nouveau table” pictured here. When imported to the

virtual environment the sharp edges were smoothened beyond the initial intention. That is due to the

way sculpted prims are rendered in Second Life, there is a practical limit to how sharp the corners can

be. Sharpness can be improved by adding extra faces around the corner.

Other third party tools used to create sculpties include SculptyPaint (all around modeler, has a specific

module to create single prim stairs), SL-PRIM-LATHE (creates radial sculpties based on 2D path section)

and SL_PRIM_EMBOSS (creates embossed sculpties based on shades of black in a 2D image).




ON OPENSIM PLATFORM

OpenSimulator, often referred to as OpenSim, is an open source server platform for hosting virtual

worlds. While it is most recognized for compatibility with the Second Life client, it is also capable of

hosting alternative worlds with differing feature sets with multiple protocols.

At the initial stage of this project a locally hosted OpenSim environment was used for early

experimentation and training with building and terraforming in Second Life-like world.

Terraformed island in OpenSim

Replica’s of the final exhibition

space at Nuggy were recreated

in this island for purpose of

training and experimenting.
