Face-Point is the first open-source real-time face filter app built using MediaPipe FaceMesh for high-performance, GPU-accelerated effects — and it’s blazing fast thanks to its pure OpenGL rendering pipeline.
⚡ No OpenCV. No fluff. Just raw OpenGL power.
# 🐞 Known Issues [FIXED]
## 🧨 Shader Crash: sampler3D on Mali GPUs
### 🔍 Issue Summary
On some Mali GPUs (often found with MediaTek CPUs), sampler3D isn’t supported.
As a result, when we fall back to using sampler2D for LUTs, the colours can appear slightly inaccurate.
- 18-09-2025 → ✅ Fixed
sampler3Dcrash on Mali GPUs by replacing it withsampler2Dfor both Mali and Adreno, keeping the same visual quality with manual slice interpolation. - 19-09-2025 → ✅ Fixed ** fixed Abstract screen glitch noise on last BW1.cube filter** by replacing it with original
BW1.cubefile. - 15-10-2025 → ✅ Fixed
glTexImage2DglError (0x502) on Mali GPUs glError (0x502) is now fixed on LUT filters.
- 🧠 MediaPipe FaceMesh for facial landmark detection
- 🎮 Pure OpenGL for rendering — no OpenCV involved
- 📱 Optimized for Android with native performance
- 🧩 Modular design for custom filters and effects
- 🎥 Encoder Logic: Based on EncodeAndMuxTest.java from Bigflake — a robust reference implementation for MediaCodec + MediaMuxer workflows
- 🖼️ Offscreen Rendering: Uses
EglSurfaceBaseandEglCorefrom Google’s Grafika test app - 🧠 Face Landmark Detection: Utilizes Google’s MediaPipe Face Landmarker — official model and API used for high-accuracy facial tracking
- 🎨 3D LUT Filter: Inspired by Svante Lindgren’s guide on creating GPU-accelerated 3D LUTs from
.CUBEfiles using OpenGLGL_TEXTURE_3D— enables DaVinci Resolve or Photoshop-style color grading directly in-app. LUTs can be embedded through code (for now), allowing custom cinematic looks and stylized filters with real-time performance.
- 🎙️ Audio recording is not supported yet
- Planned upgrade: voice changer integration
- MediaCodec logic will be migrated from Kotlin to C++ to eliminate processing overhead and boost performance
- Built from scratch with precision and performance in mind
- Designed for real-time responsiveness on mobile GPUs
- Ideal for developers who want full control over rendering and effects
