Get back 2d image from 3d model and texture map

[vidit09]

Hi Patrik

I'm using the library for fitting but also would like generate 2D image using genrated Mesh and Isomap. I've tried using the render method in render.hpp for this task but I'm not getting a proper 2d image rather image similar to the isomap. Could you please tell what does render function exactly do? Also I've tried with different model view projection values but couldn't get proper 2d image. Any suggestions in this regard will be helpful.

Thanks
Vidit

Hi,

You can have a look at how 4dface uses the render::render() function: https://github.com/patrikhuber/4dface/blob/master/apps/4dface.cpp#L235

If you want a frontal face, you can just set the modelview matrix to a 4x4 identity matrix.

Hope that helps!

Thanks Patrik. It works now!!

Hi,

I want generate 2D image using genrated Mesh and Isomap in python, but I am confused about the code: https://github.com/patrikhuber/4dface/blob/master/apps/4dface.cpp#L235. How can I get a texture from Isomap or generate python binding of render::render()? Please give me some advice, thanks a lot.

I have the same question. How to do this in Python?

Just have a look at the python/demo.py example in the eos repository, you can fit and extract texture there. Then, use OpenGL or any other rendering library in Python to render the mesh in Python in whichever way you'd like. See also #294.

hi, when i use eos.render.render(mesh, model_view_matrix,projection_matrix, image_height, image_width) get a 2d picture,but it get error ,python=3.7 eos-py==1.1.2
AttributeError: module 'eos.render' has no attribute 'render'
