Project 2 - Bread & Egg Carton - Photogrammetry Asset (Failed)

Bread & Egg Carton - Photogrammetry Assets (Failed)

    So one of my aims was to try and do a photogrammetry piece of bread and then a piece of toast however after following the same steps as I have in previous photogrammetry models I ran into another attempt that reality capture would just not do anything with. Again I spent a lot of time trying to re edit and light the photos in different formats and spent a lot of time changing settings in reality capture, however I could not produce any kind of decent result and so I decided to move on from this object and attempt something different. Below are some images for reference.

Masked Photos




    I think the issues with the bread right now is that it's shape deforms if moved and that both sides of the bread look relatively similar and so reality capture has a hard time distinguishing one side from the other and like in previous attempts just sees the camera as a fixed statice point instead of tricking it into thinking the camera has orbited the full object which is why other objects have worked well in the past. I remember various tutorials saying if the model isn't consistently the same shape throughout all the photos it could end up with bad or no results.

Reality Capture Result






    As you can see reality capture just couldn't detect enough cams in order to reconstruct the model, even after editing the photos in lightroom still the result wasn't usable as shown in the last screenshot.

    I had a similar issue with an egg carton I tried to photograph and use, however this one when reconstructing the model contained so many topolgy defects and holes that it wasn't worth trying to correct in another program like maya or blender as it would prove to be more time consuming.

    Again I tried everything from lightroom editing to reality capture settings tweaks to try and get something usable but none of it worked.

Tavern Scene - Reference Image building

 Tavern Scene - Reference Image building So this is just a quick post with a link to my pinterest board that I use for the reference images to start building the first scene of the Tavern. I decided I wanted the iconic tavern table scene so started to gather reference for tables, chairs and other miscellaneous items such as tankards, bottles, etc...  Here is the link to the pinterest board: https://www.pinterest.co.uk/lmuir2963/tavernreference-masters/ I also gathered some reference images for fantasy style weapons as I plan to implement them into the scene somehow to give some more visual information to the group of adventurers that are using the table. It also helps set the tone that they may have just come back from a quest or adventure and are enjoying some downtime. Here are some of the images I gathered on the board to provide context; All the original images can be found on the pinterest board along with others that informed my designs .

Literature Review Book 1

Image
  Literature review book 1          As seen from the image above the first book I intend to use within my literature review is titled Close Range Photogrammetry written by Thomas Luhmann and others, originally published in 2006 and looks to have been republished in 2011.      This book looks at the theory of photogrammetry as well as the practical and technical applications at the time of publication. This will be incredibly useful for me to understand the nuances of photogrammetry and expand my knowledge on the subject at a fundamental level.      The one thing I have to take into consideration is the age of the publication, as technologies and methods have advanced so much in the last 15 to 20 years or so this book while useful isn't all there is to know and after briefly scanning through the book there doesn't seem to be much reference to photogrammetry within games design, I do need a more detailed read of the book to ensur...

MA Games Design - High Poly P9 Part 2

Image
  High Poly Pistol Development     Just another quick progress update to follow on from the last post with some more screenshots of the high poly pistol development process.      As you can see in the above screenshots I added back in the trigger, slide lock and mag release button along with the front and rear iron sights. These were all pretty simple to do and most were just using the base low poly version, the slide lock I had to remodel the right side as on the low poly version there weren't enough grip indentations which caused an issue when trying to increase the detail.      As well as this I modelled in the tactile grip sections on the front and back of the pistol grip section on the lower receiver. This was a case of modelling one version I was happy with and then just duplicating it down along the sections and placing them correctly so they fit within the ergonomics of the lower receiver.
