Klartraum Studio¶

Klartraum Studio is an application for building, inspecting and tuning Klartraum compute graphs. It opens with a Gaussian splatting graph and renders it live.

Goals¶

Build and inspect compute graphs visually. Nodes stand for Klartraum’s public building blocks, and pins are typed, so invalid links are refused.
See results live while editing. Valid edits are compiled and swapped in without restarting.
Run one-off graphs. Parts of a graph that feed a preview or an image file are computed on demand.
Show what really runs. The compiled graph view shows exactly the elements Klartraum compiled, with their GPU timings.

Two kinds of output¶

A graph has two kinds of output, and one graph can use both:

Live: Everything feeding the Present node runs every frame and is shown in the window: a Gaussian splatting as it is, or processed further, for example resampled, run through ONNX models and turned back into an image.
Run: Everything feeding a Preview or Image File Writer is compiled into its own Klartraum compute graph and executed once each time you press Run (F5), or on every change with Run on every change.
