why do stocks do not appear ？

[TaXueShanRen]

I ported some of your code to Windows to make a new software，but after I choose stock file， no stock appear .
Here is part of my code:
QString path=QFileDialog::getOpenFileName(this,"select path","./");

double cx = 0.0, cy = 0.0, cz = 0.0, rx = 0.0, ry = 0.0, rz = 0.0, ra = 0.0, rb = 0.0, rc = 0.0;
StockVolume *stockVolume=new StockVolume();
stock = new cutsim::StlVolume();
stock->setProgress(0);
stock->setCenter(cutsim::GLVertex(cx,cy,cz));
stock->setRotationCenter(cutsim::GLVertex(rx,ry,rz));
stock->setAngle(cutsim::GLVertex(ra*(PI/ 180.0), rb*(PI/ 180.0), rc*(PI/ 180.0)));
stock->setCubeResolution(cube_resolution);
int error=stock->readStlFile(path);
if (error==0)
    stock->setColor(STOCK_COLOR);
stock->calcBB();
myCutsim->sum_volume(stock);
myCutsim->updateGL();
myGLWidget->reDraw();

where is the problem?

The basic concept of Open Source Code is 'Use it by your own risk'.

I ported some of your code to Windows to make a new software，but after I choose stock file， no stock appear .
Here is part of my code:

The structure of 'Cutsim' is not so simple (and I'm not the first developer of this program).
Please see 'CutsimWindow::CutsimWindow' of the file 'cutsim_window.cpp'. Do you need to create the instance of octree?

[TaXueShanRen]

I want to implement the cutting simulation so I just need to the part of the “cutsim”. I transplanted this part and see "cutsim_window.cpp". I successfully displayed the tool, but failed to diplay the stock.

[KASUYASU]

I strongly recommend you to port and execute whole 'Cutsim' program on your Windows computer, check properties of it, and after that, remove the unnecessary parts for your project.

[TaXueShanRen]

As a matter of fact, I have completely transplanted this project before, but the same problem also appeared. As you wrote in the introduction that the stocks do not display, I would like to ask the principle and process of this program to read the stock in STL format and display it.

[KASUYASU]

I'd experienced that the stock was not displayed on the screen at the loading, but after pressing the play button, it had appeared. This phenomena may be caused by the timing of executing the marching cube algorithm, but I don't know the exact reason. So would you please try the code that is uploaded on 'cutsim-q5' ? These are same program for Qt-5, and I seldom experience the phenomena.

[TaXueShanRen]

Ok, thank you very much. By the way, what are the differences between q5 version and previous version?

[KASUYASU]

The main difference is only Qt's version. But some improvements are done especially for stl file reading speed. Please try to read 'Diffuser.csim ' of the build folder.

Hi，Mr.KASUYASU.
With your help I have successfully built the software on Windows10.My goal is to do the cutting simulation according to the tool point rather than the G code.So I need to change the tool position by pos(x,y,z) and vec(i,j,k) of each cutter point.

However,when I try to achieve it,the tool position and rotation transformations are not correct.

All I did was just to change the parameters in signalToolPosition( pos.x, pos.y, pos.z, angle.x, angle.y, angle.z, current_line, motionStatus, feed_rate );I set the angle.x, angle.y, angle.z. I know it's wrong, so where do I change it?

Thanks for your help:)

[TaXueShanRen]

I find that movement includes the rotation of the stocks and the translation of the tool.To suit my needs,stocks need to keep its position and angle,but the tool both translates and rotates. I don't know where to start.

[KASUYASU]

To do the cutting simulation, you need to execute the connection chain

slotRequestMove >> slotSetToolPosition -> slot_diff_volume_mt >> slotDiffDone -> update_gl_mt >> slotGLDone >> slotRequestMove

and divide the tool motions to short sampling sections (see the inside of function 'slotRequestMove()' in the file gplayer.hpp.

To suit my needs,stocks need to keep its position and angle,but the tool both translates and rotates.

Do not give non-zero values to the angle's variables.

And I'm not your teacher. If you want to use these codes to your project, read them carefully and understand those algorithm by yourself.
