From b5ef9d915118b27ce3b5723536feec8dbfc4a8c3 Mon Sep 17 00:00:00 2001 From: nbv Date: Tue, 7 Apr 2015 17:41:37 +0300 Subject: [PATCH] 0025742: A partition of 2 shapes stresses a performance issue 1. Algorithm of aStepU1 computing was changed. 2. Interface to allow convert gp_XY(Z) to the math_Vector has been added. 3. Algorithm of point in V-boundaries computing has been changed. 4. Situation when intersection line walks along V-boundary of cylinder(s) is processed better. 5. Intersection lines are created with their individual step along U1 parameter. 6. Points processing has been moved to the assembly level. 7. Extend output of "bfuseblend" and "bcutblend" DRAW-command. 8. New option for "bfuseblend" and "bcutblend" command has been added.
