Photogrammetry Test 1 - Razer Seiren Microphone

 Photogrammetry Test 1 - Razer Seiren

    So today was my very first attempt at photogrammetry, I had watched a variety of youtube tutorials on how to setup the subject. in order to shoot it correctly for the software to recognise and create a 3D model from. My initial idea was to shoot my Razer Seiren Microphone as I wanted something that was simple but had some complex shapes and geometry embedded within it such as the plastic mesh where the voice will pass through into the microphone itself. Once I got the photogrammetry side working I would then model it via traditional methods and compare the time taken on each side and the quality of each model in comparison.

 




    So as to be expected from a first attempt at anything new that is fairly complex it didn't go as planned, the images were taken completely fine, however they were unsuitable for use in photogrammetry because of the way Reality Capture works and because I shot a completely black object on a white background Reality Capture had no way of identifying any landmarks in order to process the images correctly so it could not generate anything from them which was disheartening but still a learning experience. 

As well as this Reality Capture works in a way that it uses the position of the camera within 3D space to create the point cloud and references for the model generation, so that means typically you would orbit around the object with the camera. However because of the lighting setup after adjusting settings I had to lower the shutter speed (increase how long the shutter was open for) in order for the object to be lit properly in the photo, which meant I could not shoot hand held as there was far too much camera shake introduced into the photo from even the slightest of movements.

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

  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.
