ImPlot3D: 3D plots for Dear ImGui: lines, scatter, surfaces, meshes, rotated, panned and zoomed with the mouse.
Its API follows ImPlot’s: begin_plot(), the setup_* functions, the plot_* functions, end_plot(). Run the app
with immapp.run(..., with_implot3d=True), which creates ImPlot3D’s context.
In Python, the data are numpy arrays, and the arrays of one call must share their dtype (as in ImPlot).

Modules¶
In imgui_bundle (from imgui_bundle import implot3d):
implot3d: 64 functions, 9 classes, 22 enums · the C++ viewimplot3d.internal: 41 functions, 10 classes, 1 enums · the C++ view
Demos using it¶
The demos of the catalog that use it (the pictures link to their code and to the playground).
Butterfly effect, in a few lines¶
Two trajectories of the Lorenz system start almost at the same point, then drift apart: chaos in action.
More
Drawn in 3D with ImPlot3D. Sliders change the system’s parameters and the gap between the two starting points; Reset starts them over.
Uses: ImPlot3D, ImGuiKit
Medical imaging: a chest CT, its windows, a segmentation¶
A real chest CT, explored as a radiologist would: its slices, its windows, and a region grown from a click.
More
Choose a window preset or drag its bounds on the histogram. Click a structure: the region grows across the slices, and the app measures it and shows it in 3D. A second tab finds the blood vessels of a retina. For research and teaching, not for diagnosis.
Uses: ImPlot, ImPlot3D, ImmVision, knobs, ImGuiKit, OpenCV
ImPlot3D: the interactive manual¶
The 3D plots of ImPlot3D, section by section, with the code of each beside it.
More
Lines, scatter, surfaces, meshes and more, in Python and C++. From Dear ImGui Explorer, the interactive manual for Dear ImGui and its libraries.
