High accuracy terrain models

[WIP] This method finely approximates the ground surface by relying on deep learning to separate vegetation from potential ground points, files holes by blending multiple local approximations through partition of unity principle, then improves the accuracy by pushing the surface towards the data points through an iterative convection model.

Non photo-realistic rendering with OpenGL ES

Inspired by the EDL shading technique and SSAO, I implemented a new shader for OpenGL ES designed to enhance the rendering of point clouds. As the shading function rely only on the projected depth, and because the variable gl_FragDepth is missing in OpenGL ES, a workaround was to implement a custom depth buffer using a...

3D Poisson surface model of trees

Departing from traditional tree models made of cylinders (in green), sharper models (in blue) can be computed. Expressed as a continuous surface, they describe the shape better and allow to assess precisely the tree properties. The 3D samples and the surface model of a tropical tree can be visualize here
