ray tracing
The renderer can generate reflections and refractions. Ray tracing traces the
path of rays sampled from the light source. Reflections and refractions
generated this way are physically accurate.
rectangular break
To break a table into multiple parts that are evenly spaced and set at a
user-specified height using the table breaking grips.
redraw
To quickly refresh or clean up blip marks in the current viewport without
updating the drawing's database. See also regenerate. (REDRAW)
reference
A definition, known as an external reference or block reference, that is used
and stored in the drawing. See also block (BLOCK) and external reference (xref).
(XREF)
refine
To quadruple the number of faces in a mesh object as you reset the baseline
level of smoothness. (You cannot make a mesh courser than its baseline level.)
You can also refine specified mesh faces without resetting the baseline level
of smoothness for the object. (MESHREFINE)
reflectance scale
Increases or decreases the amount of energy the material reflects.
reflection color
The color of a highlight on shiny material. Also called specular color.
reflection line
In a dynamic block reference, the axis about which a flip action's selection
set flips when the associated parameter is edited through a grip or the Properties
paletteProperties Inspector palette.
reflection mapping
Creates the effect of a scene reflected on the surface of a shiny object.
refraction
How light distorts through an object.
