This project aims to simply and easily build Dear ImGui examples with Nelua language using Dear_Bindings as first step.
(Dear ImGui + CImGui version is NeluaImGui.)

DearBindings: dear_bindings_v0.17_ImGui_v1.92.6-docking
ImGui: 1.92.6 docking (2026/02)

Notes:

• Using ImPlot3D / ImPlot with Nelua
• Nelua + ImGui + ImPlot3D / ImPlot demo
• Build with ImPlot3D / ImPlot
• ImPlot3D integration example
• This project builds and runs Dear ImGui + ImPlot3D / ImPlotusing Nelua.
• ImPlot3D is compiled from source (implot3d.h / implot3d.cpp)
• ImPlot is compiled from source (implot.h / implot.cpp)
