 short_description: 3d meshes to sdf definitions in glsl

-Check out the configuration reference at https://huggingface.co/docs/hub/spaces-config-reference
+# Mesh to Embedded GLSL SDF Generator
+
+Upload a 3D mesh file (.obj, .ply, .stl, etc.) and generate a fully embedded GLSL `float SDF(vec3 p)` function using a precomputed 64x64x64 Signed Distance Field.
+
+### Features:
+
+- Supports most common 3D formats
+- Normalizes to [-1, 1] world-space
+- Outputs both viewable and downloadable GLSL
+
+Built with Gradio + mesh-to-sdf
