Detailed Description

Variable Documentation

Quaternion<real> auto_rotation

This is a speed in quaternion / wall-time

unsigned int auto_scale

If ( auto_scale > 0 ), the view_size is set automatically to match the simulation space. This is on by default.

Vector3 auto_translation

This is a speed in distance / wall-time

real auto_zoom

This is a speed in zoom-unit / wall-time

• auto_zoom > 0 : zoom closer
• auto_zoom < 0 : zoom away

unsigned int clip_plane_mode[NB_CLIP_PLANES]

Up to 3 clipping planes can be defined: clip_plane0 to clip_plane2

Syntax:

clip_plane? = BOOL, VECTOR, REAL

The Boolean enables the clipping plane. The plane is specified by a normal vector n (VECTOR) and a scalar (REAL). The visible half-space is defined by n.x + a > 0

Example: To define a slice perpendicular to the X-axis of width 2:

set simul:display *
{
   clip_plane1 = 1,  1 0 0, 1
   clip_plane2 = 1, -1 0 0, 1
}

unsigned int track_fibers

Possible values:

• 0 : off
• 1 : translate to keep center of gravity in window
• 2 : translate + rotate to align direction vector
• 3 : translate + rotate to align with nematic direction tensor

The translation defined by focus is applied after this adjustment.

unsigned int traveling

if ( traveling > 0 ), this sets the interval of time in milli-seconds at which the model-view transformation will be updated, by applying auto_translation, auto_zoom and auto_rotation.
