About Input Raw Data

[yuyuanzi-hub]

Hello, I want to ask that how could you build the raw data, from the coordinates of the points to the triangle vertex indices?

Are you asking about the format of a RAW file for triangular meshes?

The first line contains two numbers, representing the number of vertices nV and the number of faces nF in the triangular mesh.
From the second line to the (1+nV)-th line, each line contains three numbers separated by spaces, representing the three-dimensional coordinates of a vertex.
From the (2+nV)-th line to the (1+nV+nF)-th line, each line contains three non-negative integers separated by spaces, representing the indices of the three vertices that form a triangle. The indices are zero-based.
