Details¶

class v_sim.Line¶

Structure representing a curved line in 3D, opaque structure.

classmethod newFromTriangles(data, nTriangles, isoValue)¶

Parameters:

data (float) – the lines to be computed ;
nTriangles (int) – the surface to compute isoline from ;
isoValue (float) – the value of the computed isoline.

Returns:

the newly allocated v_sim.Line or None.

Return type:

v_sim.Line

Create on the fly an isoline from a given set of triangles. If the lines are created, isoline will be allocated and should be freed with v_sim.Line.free() after use.

New in version 3.6.

draw(rgb)¶

Parameters:: rgb (float) – a colour.

Call the OpenGL routine that will draw this line.

New in version 3.4.

free()¶: Free the line object.

New in version 3.4.

getValue()¶

Returns:: the value associated to the line.
Return type:: float

Lines are usually created as iso-values line in a mesh.

New in version 3.6.

project(plane, nSeg)¶

Parameters:

plane (v_sim.Plane) – a v_sim.Plane object.
nSeg (int) – a location to store the size of projection.

Returns:

a newly allocated array of line segments. The size of this array is 4 * nSeg, holding the two plane coordiantes of the two vertices of a line.

Return type:

float

Calculate the projection of each self vertex on plane.

New in version 3.6.

ref()¶

Returns:: itself.
Return type:: v_sim.Line

Increase the ref counter.

New in version 3.7.

unref()¶: Decrease the ref counter, free all memory if counter reachs zero.

New in version 3.7.
