WebOur project is an attempt in the implementation of the first phase of Hugues Hoppe’s PhD thesis. The publication lays out a generalized approach to the generation of a piecewise linear surface, consisting of triangular faces pasted together along their edges, from a set of unstructured points that are assumed to lie on or near an unknown surface. WebIt would be much more convenient if we could send data over to the GPU once, and then tell OpenGL to draw multiple objects using this data with a single drawing call. Enter instancing . Instancing is a technique where we draw many (equal mesh data) objects at once with a single render call, saving us all the CPU -> GPU communications each time …
