Member Function Documentation

void Timestep::calc_and_move ( )

determine the center of all the tetrahedrons.
calculates the center for use as a translation and rotation point. calculates the width of all tetras in x,y,z to set the view. moves all points to new origin center.
These two operations are combined in one function to avoid carrying around the otherwise useless max,min, etc variables

void Timestep::display ( unsigned int cmap,

bool wire,

bool pointmode,

unsigned int fillpoly,

int chunk

)

display the tetrahedrons using the cmap color scheme with wireframe.
draws the polygons assuming fill, then draw a line poly over it. can interact oddly with non fill mode. cmap must be 0,1,2

)

draw all the polygons.
do any necessary rotatation and scaling draw all the polygons enact any changes such as opaque, point view, fill, and colormap cycle translate so tet center will be at origin. perform rotation, scale draw move camera for viewability

void Timestep::dump ( ) [inline]

dump the points.

vector<Coordinate> Timestep::get_points ( ) [inline]

yeild up copy of our points.

Definition at line 101 of file Timestep.h.
References points.

bool Timestep::loadfile ( const char * filename,

GLfloat * tetcolor,

unsigned int timestep,

unsigned int chunk

)

load a tetrahedron data file.
Filename is the (path included) string of the file to load. Format of the filename should be baseChunknum.Timestamp where Chunknum and Timestamp are integers. E.g dbg_msh1.1. Loading multiple chunks at one timestep is best done with shell wildcards. Such as: dbg_msh[0-9]*.1 or even just dbg_msh* if you want access to all chunks and timestamps.
Tetcolor is a glfloat[3] with the colors of the chunk this file represents.
datafile layout is x y z r g b x y z r g b ... x y z r g b foo c1 c2 c3 c4 c5 c6 c7 c8 c9 c10 c11 c12 ... c1 c2 c3 c4 c5 c6 c7 c8 c9 c10 c11 c12 where x y z are double, r g b are float c1-c12 are integers ... means as many lines of the preceding format as you like. x,y,z are the coordinates of the vertex and r,g,b is its color c1-12 are integer indexical references to the preceding vertices counting from 0
