QUESTION
I am trying to get back and export the mesh that is being displaced by a displacementMap.
The shader is transforming vertexes according to this line (from three.js/src/renderers/shaders/ShaderChunk/displacementmap_vertex.glsl):
...ANSWER
Answered 2017-Oct-11 at 20:06To do that while still using a shader for the displacement, you will need to switch to WebGL2 and use Transform-Feedback (Google search: WebGL2 Transform-Feedback).
An alternative would be to read the texture back to CPU, and scan it while displacing the vertices using CPU only (Google search: WebGL readPixels).
Both alternatives will require some effort, so no code sample at this time. =)
