DirectX Minecraft Graphics Experimental Project

[!CAUTION] This is an experimental project that may never be introduced to a real production environment.

To put it bluntly, what this project does is basically "blindly chasing the newest things": introducing as many new features as possible, provided that it can run.

Illusion

Origins

At the beginning, the author basically just wanted to make something like Radiance, only specialized for the Windows platform.
After realizing how incapable wgpu is, he gave up on setting any more flags for Neolectrum.
Then the author discovered DirectXMod, his brain went into overdrive and produced a few mysterious ideas, and he decided to do something.
Since the original project is a rather hard-to-watch exercise in wish-driven programming (it even puts Minecraft's own source code into the repository), this project likewise keeps developing most of its code in the style of vibe coding. Real people only handle planning the architecture, the non-existent code review, and pressuring the AI into fixing bugs (not really).

Introduction

[!WARNING] This mod is still in early development; it is yet another of the author's hole-digging projects that may never be finished.

Illusion is a Minecraft NeoForge mod based on Microsoft's DirectX 12 backend, aiming to bring advanced graphics features to Minecraft — ray tracing (not implemented), mesh shaders, temporal anti-aliasing, NVIDIA's whole Streamline suite (deep learning super sampling, frame generation, ray reconstruction and ray denoising), and more.
It also takes advantage of DirectX's strengths on the Windows platform and Microsoft's PIX diagnostic tools to create an experimental platform that is easy to develop on.

MCDR

Overview

Because it learns from (copies) Radiance, the project is organized the same way: the dynamic link library lives in its own repository, named MCDR — a rather hasty decision, to be honest.

Details

• DirectXMod was implemented with JNI. Following the changes in Minecraft 26.1 — the game dropped deobfuscation and upgraded Java 21 to Java 25 LTS, the first LTS release after the FFM API left preview — this project replaces the whole JNI implementation with the Java FFM API, which is theoretically faster and makes calling and implementing native code safer and easier.
• Since release-26.3, the game has switched from LWJGL to SDL, which makes it easier to wrap the backend presentation (26.4-snapshot-5 already introduced a native DXGI-wrapped presentation path). This mod therefore gives up on 26.2 and raises its target Minecraft version to release-26.3 for the next stage of development.

Only the Intel XeSS runtime ships inside the mod JAR. The NVIDIA DLSS and AMD FidelityFX runtimes are not redistributed: a released build reports those SDKs as unavailable unless you place the vendor DLLs next to MCDR.dll yourself, and development builds stage them into run/dxrmc/ via gradlew copyVendorDlls.
