• Checking the help pages for stepconf
• Trying to solve segmentation error

26 June

Pre-midterm Evaluation Summary

I have started my GSOC with part primitive. Its easy for me to export coordinates of part. Then I export part into POV-Ray by using Round_Cone2 object. In next week it started exporting Ell. I found it difficult as I was not able to rotate ellipse but in last I export ell into POV-Ray by using spheroid object. In week third, I was working on arb8. Its harder for me to export. So I discussed it with POV-Ray community and finally I wrote a macro and I was able to export arb8 successfully. In 4th week, I export tgc successfully. In last week, I clean up code and submit POV-Ray converter as a patch. I was also working on Linuxcnc in these pre-midterm days. I wrote stepconf help pages that will be used while user click on help button of stepconf of linuxcnc.

I have exported many other peimitives into POV-Ray. After mid term evaluation I discussed with my mentor about linuxCNC project. Due to lack of knowledge about linuxcnc machines and motivation we decided to move with POV-Ray export project. So I started exporting primitives into POV-Ray. I was feeling difficult to choose between primitive so I discussed it with my mentor. He gave me a list by which I was able to work in order. I have exported many primitives as listed below RHC, RPC, EPA, EHY, ARBN, Half, ELL1, ELLg. One of these primitive is BoT which required some modification. I was in difficulty in exporting it but after spending time on it I was able to export it successfully and now its working correctly. I also exported HRT primitive in POV-Ray but its not similar to heart. But I'm very thankful to my mentor who gave me a chance to increase my skills and motivation to do work with proper methods as I never expected that I will able to export these given primitives in proposal opn time but thanks to mentor and God who motivate me to work and I was able to export more primitives along with those given in proposal.
