Diablo 1 in a new dimension.
Diablo3D is Douglas Pan’s project to recreate all of Diablo 1 in 3D, built on DevilutionX. It uses AI in code, copy, artwork and new music recordings. It is a very early, unstable prototype.

Douglas Pan leads the project.
Douglas sets the goal, chooses references, requests corrections and tests builds. He uses AI to write code and copy, generate visual studies and produce assets. New Diablo3D work is not presented as handmade.
How we use AIWhy add new cameras?
Explore Tristram and the dungeons from within in first person, or follow the hero in third person. DevilutionX simulation keeps the game rules; F4 lets you compare the scene with the original view in the same session.

COMMUNITY · FREE PROJECT
Contribute code, artwork or testing.
Human review, models and bug reports help improve the prototype. Sharing also helps. Financial support is voluntary.
PANVIA · RECOMMENDED PATH
Installation in preparation.
The public package and Panvia integration still need validation. For now, GitHub provides source and build instructions. A future installation must preserve saves, settings and rollback.

Cathedral: native materials and lighter transparency
The first-floor pilot receives floors, masonry and wood from the original, with explicit visual approximations. Regional copying reduces the measured transparency cost; shapes, doors and gameplay still need review.

Portuguese narration · English subtitles
Gameplay recorded by Douglas and historical previews. The narration records preparation before Ogden and the Cathedral pilot were integrated; artwork, camera behavior and performance remain under review.
MODELS IN DEVELOPMENT · WIP
Griswold and Ogden in 360°
A 28-second preview of the two models in development, with a main horizontal video and a Short of the same characters.
These are visual studies under review. The videos do not show gameplay or establish in-game integration or artistic approval.

ONE GAME SESSION, TWO VIEWS
The game continues.
The camera changes.
F4 switches between the original view and the prototype within the same game session. Movement, collisions, inventory and interaction still use the DevilutionX simulation.
Home restores third person within the session. F4 still switches native and 3D presentation; geometry fidelity requires comparisons with the mesh enabled.

The journey begins
in Tristram.
Tristram and nine regions of the first normal Cathedral floor form the local pilot. The goal includes every level. Loading, artwork, combat and performance still need review.
