Tldr: We had a mistake in the upstream. Please pull again.

 

Dear Students,

we failed to correctly update the upstream for practical 4. There are missing functions in instance.cpp and instance.hpp that we added in a new commit in the upstream. Without these functions the transmittance function of the volume shape will never be called.

In order to have a functioning volume implementation you need to pull and merge the upstream again.

Sadly, it is possible to pass all test with a wrong implementation of the transmittance, so make sure to double check your implementation of the transmittance function in the volume integrator. 

Dear students,

thanks to your help we found a bug in the Lightwave reference for Assignment 4 which caused the bounding_volume test to fail even if your implementation was correct. 
In order to ensure you are working with correct reference renders you should pull the upstream again and merge it into your repository.  

The final exam will take place on Tuesday, 17 February 2026 in the Günter Hotz lecture hall (E2 2) from 14:00 to 16:00

The re-exam will be on Tuesday, 17 March 2026 in E1 3 HS002, also from 14:00 to 16:00

You can also find these times in the calendar on CMS (https://cms.sic.saarland/cg_25/termine/calendar/index)

Dear Students,

We have just released the tutorial slot assignments.

Next Steps:

• Registration for submission is now open and can be found under the "Personal Status" tab.
• The deadline for team creation is October 26th at 23:35.
• Make sure that you and your teammate are in the same tutorial slot.
• To find a partner, you can consult the forum, where a dedicated thread already exists.

Welcome to the course :) There are a few things you need to do for a smooth start into the semester.

On your personal status page in CMS, please:

1. Fill in your tutorial preferences (Deadline on Sunday, 19.10.)
2. Provide your SIC account name for git repo access (if you are unsure about the account, check https://sam.sic.saarland/)

Regarding tutorials:

• Next week, there will be a tutorial, in your assigned slot, to guide you through the process of setting up the framework for the practical assignments. 
• Afterwards, the tutorial slot will be used for the mandatory code interviews (during lecture weeks only; there are no tutorials during office hour weeks)
• If you already have a favorite team partner: Both students in a team must be in the same tutorial, so please try to provide the same preferences. If you end up assigned to different tutorials, get in touch with us and we'll see what we can do.

Finally, if you have changed your mind about taking the course, you can unregister (personal status page on CMS) to avoid getting spammed with notifications and requests for missing info.
