Thank you for your excellent work!
When I try to compile your code,I get some trouble.Could you please check for the error?If you have encountered it,please tell me the solution.Thank you!

CMake Warning at CMakeLists.txt:36 (find_package):
By not providing "Findrealsense2.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"realsense2", but CMake did not find one.

Could not find a package configuration file provided by "realsense2" with
any of the following names:

realsense2Config.cmake
realsense2-config.cmake

Add the installation prefix of "realsense2" to CMAKE_PREFIX_PATH or set
"realsense2_DIR" to a directory containing one of the above files. If
"realsense2" provides a separate development package or SDK, be sure it has
been installed.

Thank you so much about your kind reply!
I've noticed this issue and I compile your code successfully in docker with the dockerfile provided by #2 (comment).
However, when I try to run it, it seems another error occurred. So confusing it is that seems nobody have met this before. Could you please check for it and provide some suggestion?
Thanks a lot!

Hi Xiang, Sorry, I don't get your questions. Is it the same problem as #5? Please provide further details.

@HuajianUP @Jiyu-Yao Hi all, I encountered the same issue with the dockerfile provided by #2 (comment), hard to debug with the segmentation fault, any updates with this issue?

have same question, too

I changed release mode to debug mode in cmakelist and then realized that the problem seems to be here

in imgui_viewer.cpp remove line 485 such as

//--------------ImGui Rendering--------------
ImGui::Render();
// ImGui_ImplOpenGL3_RenderDrawData(ImGui::GetDrawData());

//--------------Draw main window SLAM--------------
// Set relative viewpoint
glPushMatrix();

The code can output the rebuild results normally, but it cannot display the build map in real time. Maybe there is a slight problem with this part

I found that

           (GLsizei)pcmd->ElemCount, 
           sizeof(ImDrawIdx) == 2 ? GL_UNSIGNED_SHORT : GL_UNSIGNED_INT, 
           (void*)(intptr_t)(pcmd->IdxOffset * sizeof(ImDrawIdx)), 
           (GLint)pcmd->VtxOffset)
           );

pcmd->IdxOffset and pcmd->VtxOffset both is 0，They may represent base addresses in memory

I noticed that the vtfofffset and idxoffset just don't seem to be quite right here.

    ImGui_ImplOpenGL3_SetupRenderState(draw_data, fb_width, fb_height, vertex_array_object);

    // Will project scissor/clipping rectangles into framebuffer space
    ImVec2 clip_off = draw_data->DisplayPos;         // (0,0) unless using multi-viewports
    ImVec2 clip_scale = draw_data->FramebufferScale; // (1,1) unless using retina display which are often (2,2)

    // Render command lists
    for (int n = 0; n < draw_data->CmdListsCount; n++)
    {
        const ImDrawList* cmd_list = draw_data->CmdLists[n];

  
       // std::cout<< draw_data->CmdLists[n]->CmdBuffer[0].VtxOffset<<std::endl; // 0
       // std::cout<< draw_data->CmdLists[n]->CmdBuffer[0].IdxOffset<<std::endl; // 0
       // std::cout<<"~~~~~~~"<<std::endl;
