STL import not working well

[rajpiyush18]

I am working with the following file
angled_square_needle_v1.zip

I am using the following command:

theta = -pi/2;
A = 0.1*[1 0 0 ;
0 cos(theta) -sin(theta);
0 sin(theta) cos(theta)]; % Rotation around the x axis with -pi/2

% and then translation
v = [-0.1 -0.025 3.108];

It is working when
v = [positive x value, -0.025 3.108];

The moment I put a negative value for x, it doesn't seem to work

Other details:

model.G.nx = 200; % Number of bins in the x direction
model.G.ny = 200; % Number of bins in the y direction
model.G.nz = 200; % Number of bins in the z direction
model.G.Lx = 0.8; % [cm] x size of simulation cuboid
model.G.Ly = 0.8; % [cm] y size of simulation cuboid
model.G.Lz = 0.8; % [cm] z size of simulation cuboid

Thanks for the bug report! I managed to track down the bug to the function VOXELIZE, which I originally got from the Mathworks FileExchange. I found a fork of it, written by W. Warriner, who fixed this bug and many other improvements. I will replace the VOXELIZE function in the next release of MCmatlab, but in the meanwhile if you put these files into the helperfuncs folder it should fix the issue:

Unzip me into helperfuncs.zip

Let me know if it works or not.

Thank you so much @ankrh. This works very nicely.
