Contents

Action

Sets whether or not approximations can be used for vertex blends.

Name String

approx_vbl_offset

Scheme

Type Values Default
boolean #f, #t #t

C++

Type Values Default
logical FALSE, TRUE TRUE

Description

When TRUE, vertex blends are not offset exactly, but the resulting surface is quicker to evaluate and better behaved. When False, the offset is exact, but slow to evaluate and prone to self-intersection.

Example

; approx_vbl_offset 
; Turn off approx_vbl_offset 
(option:set "approx_vbl_offset" #f) 
;; #t
