#43 | fixed | ModelGeometry: sizes and orientations depend on sampling density and model orientation | ||
Description |
Testing a ball (genotype Windows+Visual Studio 2013 compilation, %g: 0.1 12.5664 0 [(2.0,2.0,2.0),Orient@(-0,1,0)] 1 12.5664 1.01829 [(2.0,2.0,2.0),Orient@(-0,1,0)] 2.5 12.5664 1.98001 [(2.0,1.9986484217435,1.97326669133902),Orient@(-0.415242,0.498119,0.472743 )] 4.32175 12.5664 2.97095 [(2.0,2.0,2.0),Orient@(-0,1,0)] Windows+Visual Studio 2017 debug compilation, %.17g: 0.10000000000000001 12.566370614359172 0 [(2.0,2.0,2.0),Orient@(-0,1,0)] 1 12.566370614359172 1.2728649512171213 [(2.0,2.0,2.0),Orient@(-0,1,0)] 2.5 12.566370614359172 2.2275136646299623 [(2.0,1.9986484217435,1.97326669133902),Orient@(-0.415242,0.498119,0.472743)] 4.3217451999999996 12.566370614359172 3.1994853921717938 [(2.0,2.0,2.0),Orient@(-0,1,0)] So for density=2.5, the computed orientation is weird. Same test, this time linux+gcc, different result (%g for now): 0.1 12.5664 0 [(2.0,2.0,2.0),Orient@(-0,1,0)] 1 12.5664 1.01829 [(2.0,2.0,2.0),Orient@(-0,1,0)] 2.5 12.5664 1.98001 [(2.0,2.0,2.0),Orient@(-0,1,0)] 4.32175 12.5664 2.97095 [(2.0,2.0,2.0),Orient@(-0,1,0)] Identify causes of this influence/non-determinism and eliminate if possible. |

#44 | fixed | ModelGeometry: for cuboids, sampling points should be located on edges | ||
Description |
Improperly placed sampling points (missing one "row" along edges? needs verification) may be the reason for inaccurate estimation of cuboid sizes. Test with: frams "var m=Model.newFromString(\"//0\np:sh=2\n\"); var mg=ModelGeometry.forModel(m); mg.geom_density=2; Simulator.print(mg.sizesAndAxes());" -q Instead of nice round numbers, we get [(3.46410161513775,3.2659863237109,2.82842712474619),Orient@(-1.5708,0.61548,0.785398)] |

#46 | fixed | ModelGeometry: add support for shape=0 (cylinder) | ||
Description |
As the first step while shape=0 is not yet supported, the source should print an error message and return 0 (or treat cylinder as a cuboid) instead of crashing as it currently does. Test with: frams "var m=Model.newFromString(\"//0\np:sh=0\n\"); var mg=ModelGeometry.forModel(m); Simulator.print(mg.sizesAndAxes());" -q |
