ork_renderer's Issues

Texture rendering

Currently doesn't work, as mentioned in wg-perception/linemod#10
A hacky fix is there (mentioned in the link)

load model issue

  scene->mMeshes[i]->mVertices[j].x *= -1;
  scene->mMeshes[i]->mVertices[j].y *= -1;
  scene->mMeshes[i]->mVertices[j].z *= -1;

when you load the model,why you multiply -1

Illegal glut reinitialization attempt when using several objects

GLUT fails reinitializing the renderer for training the second object.
For now I have to look for object id myself, type it in training.ork and train them one by one

Training 2 objects.

Linemod issue

I think that this issue is actually in this respository!

No sample files to test with

It would be good to include some example 2d (png) or 2d files that could be used to test the renderer and planar trainer. I had to reverse engineer the png file format encoding for depth and the mask...

Merge pull request #5 from nlyubova/master breaks compilation of linemod_train.cpp

Since render was changed from 3 args to 4 args.

render(cv::Mat &image_out, cv::Mat &depth_out, cv::Mat &mask_out) const = 0;
+ render(cv::Mat &image_out, cv::Mat &depth_out, cv::Mat &mask_out, cv::Rect &rect_out) const = 0;

Either update the other packages that depend on ork_renderer or have backward compatibility in ork_renderer by having another render function with 3 args.

Can not catkin_make this package

When I run catkin_make I always face this problem. Anyone knows why?

Compile error OpenGl

Hello,
i get the following compile error. Any ideas?
