Hello Madam or Sir,
I am the user of OpenMesh, and I want ask some questions about the parallel code with OpenMesh, exactly, the parallel code is based on OpenMP on the VS2013.
The first question: When I use the OpenMP on the VS2013 to speed up the program which write with OpenMesh, for example, I add the code: #pragma omp parallel for num_threads(7) , just like the following:
and the errors follow, and I do not know why.
and the second question: Could the code with iterator of OpenMesh be paralleled by OpenMP just like " for (TriMesh::FaceIter f_it = mesh.faces_begin(); f_it != mesh.faces_end(); f_it++) " in the above picture? or How can I parallel the code with iterator of OpenMesh?
Thank you for your time! And I am looking forward to your reply.
Sincerely
LuWang
Hi,
I would like to report a bug in OBJReader of Open Mesh. I have written a
program to read OBJ files and to render them using OpenGL. This program
uses OpenMesh for loading files. When I load the attached file
(CubeCol.obj), the program displays a gray coloured cube instead of a red
cube (CubeCol.mtl defines the colour of the cube as red). All other object
loaders and viewers (including Windows 3D viewer) displays the cube
correctly with a red colour. I spent hours trying to identify the problem,
and finally found out that if I remove the space character at the beginning
of the last three lines in CubeCol.mtl, the cube gets displayed correctly.
Apparently, OBJReader ignores lines in the mtl file where there is a space
character in the first column. All other obj readers that I have used load
the file correctly.
Also, I have noticed that it is not sufficient to request face colours
(mesh.request_face_colors()) before reading the mesh file to get the colour
values from the mtl file. I also had to include IO::Options::FaceColor as
the argument for the read_mesh() function to get face colours using
mesh.color(faceHandle); I couldn't find any documentation giving the
actual procedure for loading data from mtl files. Please let me know if I
am using the correct method for loading obj files along with material
properties.
Thank you.
Kind regards,
