I know that poisson does change the original input cloud , but is there a way to tell it that for each point in the reconstructed mesh , adopt the color of neares point in input cloud. Also, even I could achieve this, I believe that the results will not be good , as the number of points is downsampled.... It's best to divide up your terrain mesh in chunks, and do some culling on the CPU, and only draw (partially) visible chunks. This is a process that is referred to as Frustum Culling. And this video is an excellent illustration of how it works.

The way I do it in openGL ES2.0 (no instancing, just like GL3.2), I have an object class that stores the mesh, standard materials for the mesh, textures, and a render function for rendering the mesh as is. Each object is unique. I then have instance objects, that carry a reference to the object they're an instance of, along with stuff like model matrix, child instances, instance specific...
A few remarks on this code : For now, our 3D model is fixed : in order to change it, you have to modify the source code, recompile the application, and hope for the best.

I am willing to develop a GUI for a scientific software, which will use a mesh visualization tool. I found the Wireframe example which makes me want to start using Qt. However, it uses a general material model that seems

  • OpenGL's color material feature provides a less expensive way to change material parameters. With color material enabled, material colors track the current color. This means that instead of using the relatively expensive
  • I'd like to have some nice effect when I hoover the mouse over eash mesh, that the specific mesh the mouse is hoovering over, the mesh boundary will become highlighted (changed color, line thickness) and that I will know which triangle it is (number is fine), so I can keep track of a user selection..
