Focal length derivatives are obtained from opencv, but (unlike all the others) doesn't seem to match finite differencing very well. Maybe it's a problem in OpenCV, maybe in OpenDR.
I have been working with reconstructing people from 2d image into 3d representation. i have been working with a code in github where in it they reconstruct the 3d representation of the human but they are represented in the 2d image itself,but i need it as 3d format and could be saved in such a format. Is there anything i can do using opendr to solve this issue
Happy Labor's Day!
I have installed OSMesa from source code and installed opendr by pip install opendr
successfully.
But when I import opendr in my python code, I met the following error.
ImportError: "/..//opendr/contexts/ctx_mesa.so: undefined symbol: _ZTIN4llvm11RuntimeDyld13MemoryManagerE"
PS: I install OSMesa from this script osmesa-install.sh
Environment:
Ubuntu 16.04
Python 2.7
who can help me? Thanks a lot
It seems today I am unable to install opendr. I've not had trouble with it in the past. When I install with pip, it gives the error /usr/bin/ld: cannot find -lOSMesa
collect2: error: ld returned 1 exit status
.
Also, I noticed that the mesa website seems to be down:
https://www.mesa3d.org/osmesa.html
Perhaps these two issues are linked? Has anyone else had this issue, and if so, what is the workaround?
Thanks!
Henry C.
An error was occurred to me whill installation.
UnicodeDecodeError: 'utf8' codec can't decode byte 0xb3 in position 0
The problem is located in

Hi,
Is it possible to get the depths of mutiple triangles that will be projected on a pixel during rasterization stage using opendr?
Thanks for any help.

means
and hopefully could you please tell me how to look up for the reference book?because currently i can only find 2 tutorials?
thanks.

The parameter normalization
to opendr.filters.gaussian_pyramid
is parsed incorrectly; it should be compared using ==
instead of is
. This causes weird behavior when using the function:
gaussian_pyramid(..., normalization='SSE') # works
gaussian_pyramid(..., normalization='SSEE'[:3]) # fails, throws TypeError
Make it faster
I have the problem while running the same problem of the demo point_light. But it calls the error of"AttributeError: 'Minimal' object has no attribute 'v'",so how to solve it. many thanks

Can you help me?
I was using Python3 and tried to install OpenDR via pip. But I failed and found opendr now seems only compatible with Python 2? So can I know is there any plan to move opendr forward to Python 3? And is there any way I can overcome this currently?
pip install opendr==0.77, and it is successfully. Then, enter into the environment of python, input the test of demo "import opendr
opendr.demo('spherical_harmonics')".
But the error is as below:
"Traceback (most recent call last):

When I try to install the package in ARM processors it gives the following error Exception: Unable to get url: http://files.is.tue.mpg.de/mloper/opendr/osmesa/OSMesa.Linux.aarch64.zip
as the file is missing.
Hey Matt,
Not sure if this is correct form (creating an issue after a PR) but I wasn't sure so here'a link to the PR that describes our problem in some detail.
Once again, we'd be delighted to chat with you on this.
Thanks,
Mayur

I would like to use the FramebufferTexture2D and CheckFramebufferStatus fns of OpenGL through opendr. Is the functionality for the same available? If so, please guide towards the same.
It seems that wiki and codes are designed for perspective projection camera model. How can I render mesh to image space when I assume orthogonal projection camera model?
This should do the same thing that numpy does, but it raises an exception instead:

Hi,
The setuptools fix around here: setup.py#L25 is not needed anymore, and it actually prevents a successful install on ubuntu 15.04, python2.7 by throwing the error:
AttributeError: Extension instance has no attribute '_convert_pyx_sources_to_lang'
It seems ok to comment out lines 25..27.
Thank you for your wonderful job on building this amazing differentiable renderer. I am currently trying to reimplement experiment in your ECCV 2014 paper.
Well, I have two question
(1) How to improve the quality of texture rendering? I mean I tried several demos and also my own mesh data, the texture rendering looks blurring. For example, even in the earth demo, your own example(uses an earth map picture as the texture image) lines do not look sharp after rendering. I know that, if you simply use a png image as a texture image, it becomes blurring due to the enlarge and shrink. So can we use vector format image as a texture? Or in general, how to improve the visual effect in general? I mean your ECCV paper showed amazing indoor rendering scene, how can I have the same level of rendering result? Do you have materials so I can re-implement this experiment?(if you willing to share, that will be great. otherwise some general guides will also helps me a lot)
(2) How is your workflow/utility of editing the data you suggest me to do? I mean the OpenDR provides the render API, which is very nice, but I found so far I spend a lot of time to extract the data from a 3d model file and import data, nevertheless to editing it. For example, if I have multiple texture files, I have to manually put the texture data together as one image, then give it to the TexturedRender. Does the OpenDR provide some file reading utility, so I can edit a 3d object in another editing tool and them save it as some file format, then the OpenDR just read the file format and do the rendering? By the way, what editing tool you suggest to use for most convenience?
Thank you so much for answer my question.
I use pip install opendr but fail.

Hello!
I want to render a 3D model and get its silhouette using opendr, and then use this silhouette to calculate the cross entropy with the label mask image. I am wondering if it is differentialble during the training process......
Could this method work?
m = load_mesh('file.obj')
1.When I run demo('optimization'), I load my own obj file and display this error. ValueError: invalid literal for int() with base 10: ''
2.
It seems that we don't need set camera intrinsic parameters when use ProjectPoints to render. Is this because of fixed intrinsic parameters? If yes, can you share these parameters? Because I have to know these parameter to make a proper projection image.
Can we use this libray to render the output and save it in smpl model format ?
Please suggest.
Any sample to save the output in smpl model format would be helpful.
Not really an issue, more of a question. Is there a way to retrieve the visible from a given viewpoint vertices?
first modify _functions.pyx:
change line 640: glBindVertexArray to glBindVertexArrayAPPLE
second modify gl_includes.h:
replace from line 14 to the end:
#ifdef APPLE
#define GL_SILENCE_DEPRECATION
#include <OpenGL/gl.h>
#include <OpenGL/gl3.h>
#include <OpenGL/glu.h>
#include <OpenGL/OpenGL.h>

Good afternoon,
I have been struggling for some time to make OpenDR work in some other project I have found on github (https://github.com/silviazuffi/smalr_online). So, apparently, even though the renderer parameters, vertices, faces etc seem to make sense, the r
it returns contains only zeros. The rendered image is then empty.
Some other script (https://smpl.is.tue.mpg.de/downloads -> Download version 1.1.0 for Python 2.7 (male, female, neutral all with 300 shape PCs) -> smpl -> smpl_webuser -> hello_world -> render_smpl.py (cannot share the code) seems to actually render the image properly, though the input and the renderer setup are very similar.
Is anyone familiar with a similar issue? I use Ubuntu 18.04, Python 3.8, latest version of opend
from PyPi.
when my code goes to
ch.minimize( 'pyr': E_pyr), x0=free_variables, callback=cb) in optimization demo,
the error says the 'pyr': E_pyr is float object not integer(which is needed).
But when I look up the definition of minimize function, it does not mention the type of the first parameter.
Has someone met this problem??
I am using Ubuntu 18.04, CUDA 10.1 Python 2.7.15. The following issue does not happen in any other machines in my lab but they are Ubuntu 16.
I have followed instructions on https://github.com/mattloper/opendr/wiki/Installation-in-Ubuntu
I then run opendr.demo('point_light'), but only a black image comes up, not the sphere mesh with one point light source. Here is the error message:

Moved to chumpy Issues!
From numpy doc:
If a has more than two dimensions, then broadcasting rules apply [...]. This means that SVD is working in “stacked” mode: it iterates over all indices of the first a.ndim - 2 dimensions and for each combination SVD is applied to the last two indices.
https://docs.scipy.org/doc/numpy/reference/generated/numpy.linalg.svd.html
When calculating the derivatives for SVD chumpy assumes 2D arrays:
line 196 of linalg.py
:
result = np.einsum('ik,jk->kij', u, v)
line 214ff of linalg.py
mxsz = max(shp[0], shp[1])
D = np.zeros(mxsz)
D[:_D.size] = _D
The only workaround I see right now is looping over the dimensions outside of SVD (slow).
Thanks for the wonderful project!
I would like to render a mesh with wireframe. I was wondering that would it be possible to use opendr to render only the wireframe? Any advice and suggestions will be greatly appreciated!
