Hi Roger ... It could be done as e.g. vec4d HSVA = col_val(R,G,B,A).get_hsva(); ... There aren't that many parameters, so I don't think an extra one would be a

Hi Adrian, This is the smaller file created showing the UC28 intersection. I used off_util -x V on the previous file. (-x V isn't in the help). I think is is

Hi Adrian, ... Over the weekend I thought of an efficient algorithm (conclusion to the above) to split each triangle based on the edges and vertices of the

Hi Adrian, ... Did you have to calculate a conversion factor for these? ... Getting the scene looking right was challenging for off2m. It finally came to the

Hi Roger ... I have just added this in. There is still a slight incompatibility as the original default element sizing is tied to the bounding box diagonal,

Hi John ... It makes your program more useful if you change your main function. The idea of passing the command line parameters to glutInit is to allow certain

Hi Roger ... I haven't added your sort_merge changes in yet so I will make the snapshot without them and then wait for this extra change before adding them in.

Hi Roger ... The functions are different. Your function looks like a "less than" function, whereas the compare() function returns -1:less than, 0:equal,
