Project 2 - Egg - Photogrammetry Asset

Egg - Photogrammetry Asset

    To save repeating most of the information of the initial steps of creating a photogrammetry asset I will just post the screenshots in order below.

    This time I skipped the lightroom step and went straight to reality capture as the lighting was already pretty flat due to the material of the egg shell it diffused lighting really well and I felt it unnecessary to go through lightroom first before trying reality capture.

Reality Capture Model




    Again really happy with how this model turned out and that even skipping the lightroom step didn't cause me any issues. At this point I did notice some defects on the texture and I decided to try and rectify these as well as adding in a couple more steps with new software to get the best result.

    I found tutorials on photogrammetry where a new step was introduced and that was to use the free texture delighting software that Agisoft provides, this is a very easy program to use and it produces nice flat lit textures from already created photogrammetry assets. It requires both the model and the texture in order to work, below are some screenshots of this process.



    The first step is to load the file into Agisoft as seen above.



   Then using their pen masking tool, the blue colour is used for removing shading and the yellow colour is used for removing highlights and cast shadows, you paint the areas where you can see the texture is being affected by highlights and shadows. Since it was my first time using this software I decided to just paint the whole egg to ensure all of the lighting and shadows was removed.

    
Then over on the right you can select what you would like to remove and Agisoft processes a new texture from this. And as you can see the results were fantastic and exactly what was needed in order to improve the assets further.

Texture Comparison


The left side was the original texture from reality capture and the right side was the new delit version from Agisoft. I am happy to have found this new process and will be incorporating it in future photogrammetry assets.

Substance Renders




    Because this is by far my best photogrammetry asset I decided to load the textures into substance along with the normal map from reality capture and do a few renders so I can eventually put this into my ArtStation portfolio. The quality is really amazing and I am happy with the end result of this.

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.
