DJM: Compact Base Meshes for Displacement Mapping using Triangle Jacobians

[Project Page]

---

Usage

Template for running DJM base mesh construction:

djm <input_mesh> <output_folder> <target_face_number> <average_subdiv_level> <max_subdiv_level> <max_normal_threshold> <max_jacobian_threshold>

Example for running DJM base mesh construction:

djm ./data/Armadillo.obj ./output 1 4 5 80 0.5
