the way tMax is calculated covers only one quadrant of directions

I'm trying to understand the suggestion on how to compute `tMax` which is describes as below ``` // grid.minBound.x is the lower left corner of the grid. // current_X_index is...

while loop may never exit (solution would be to check tMaxX, tMaxY,tMaxZ to surpass T1)

while (current_X_index != end_X_index || current_Y_index != end_Y_index || current_Z_index != end_Z_index) if for whatever reason these indexes never happen the loop will hang forever. I am not yet sure...

Code like this, seems to set the index to a minimum of 1 ? Why do that ? Does this code assume the voxel grid starts at index 1,1,1 ?...

SkybuckFlying

Ray direction is not computed by the code/algorithm, I noticed this while trying to apply the code. Fortunately it does not seem to complex, though it could get a bit...
