Hi,
I tried this suggestion and the following works well:
lineArray = new LineStripArray(Integer.MAX_VALUE, LineStripArray.COORDINATES |
LineStripArray.BY_REFERENCE, new int[]
{coordinates.length/3});
I am obviously not passing in an array of floats this long (length of 96 first up) and
all seems to work fine. My question is
now, does setting the vertex count to such a large value waste4 any memory / resources
etc?
Cheers,
Brad
