Texture mapping on the clandestinely scanned bust
--
The texture was retrieved from my previous [photogrammetry model](https://skfb.ly/GWMR), while the 3D object was downloaded from [AD&amp;D 4D](https://skfb.ly/6QUFB)' Sketchfab model. 

The combination of these two models was completed with **MeshLab**, using the very efficient "Point Based Gluing" alignment method.

Finalization with realistic lightings performed in Sketchfab.

A Hindu temple, or mandir or koil in Indian languages, is a house, seat and body of divinity for Hindus. It is a structure designed to bring human beings and gods together through worship, sacrifice, and devotion. The symbolism and structure of a Hindu temple are rooted in Vedic traditions, deploying circles and squares. It also represents recursion and the representation of the equivalence of the macrocosm and the microcosm by astronomical numbers, and by "specific alignments related to the geography of the place and the presumed linkages of the deity and the patron". A temple incorporates all elements of the Hindu cosmos — presenting the good, the evil and the human, as well as the elements of the Hindu sense of cyclic time and the essence of life — symbolically presenting dharma, artha, kama, moksa, and karma

This unlucky BMW Series 3 E36 car, actually suffered two accidents. Besides the nasty, physical road traffic collision, the photogrammetric alignment produced a poor virtual result due to the high reflectiveness of the vehicle's body and windows.

Machu Picchu is an Incan citadel set high in the Andes Mountains in Peru, above the Urubamba River valley. It was built in the 15th century by the Inca empire and later abandoned. It is renowned for its sophisticated dry-stone walls that fuse huge blocks without the use of mortar.  Many intriguing buildings of archaeology are on astronomical alignments and yield stunning panoramic views. Its exact former use remains a mystery.  -Nate Loper

## Scanning
The scan was created in large IR-mode with automatic exposure and geometry tracking. I started from the front and slowly moved around the part while keeping an eye on having enough overlap for tracking (rotating the scanner to reach in to the crevices works quite well to circumvent obstructions due to limited line of sight). While scanning the framereate was roughly 10 FPS with some highs to 15 and lows to 6 FPS (NIR mode still needs an update I guess, currently no marker scannign supported).

## Post-Processing
For post processing I fused the scan at 1mm and and meshed it it with default settings. For alignment I used the untegrated tooling in Creality Scan (basically rotating the part until alignment is right). The figurine then was printed from PLA to create a minature version.

## Scanning
The scan took place in two steps: First the top of the lawn mower and then the bottom. For both scans I didn't use any scan spray or similar, just took the scanner and started scanning at 1mm resolution. Since then markerless laser scanning made quite some progress, especially in wired mode where scan speed was increased from 20 FPS to 60 FPS with the latest update. Hopefully this will also transfer to wireless mode in the future. 

## Post-Processing
Processing just consisted of generating the point cloud when finishing the single scans, aligning the scans to each other (I used manual feature alignment since the overlap was quite minimal) and then I meshed the scan with default settings. Only divergence from default was using the semi watertight setting since it delivers a more closed model without too much "artistic freedom" to close holes. The scan was then reduced and aligned in Quicksurface.

## Scanning
One single scan with the Trackit was taken, this also is the reason for the missing part on the left bottom since a cupboard prevented line of sight between the tracker and hand piece. To reach the target resolution roughly 13k frames were scanned which comes out to 4min of scanning at 53 framer per second average.

## Post-Processing
I focused on the top part of the scan and used 0.4mm for fusion and meshing without any hole filling. The third image shows the raw captured data with the whole door. Alignment was done in Quicksurface as well as some slight reduction in polygon count to enable Sketchfab upload.

## Scanning
Scanning was done at 2mm target resolution and no scan spray was used. I was to lazy to calibrate the Trackit so some of the surface quality defects may be accountable to this problem. Tracking quality was indicated as poor so time to calibrate. Scan was performed in three parts (could have been two but the first placement of the tracker was suboptimal) and each scan consists of paint brush movements until full data quality was reached.

## Post-Processing
Processing work was minimal by first fusing at 1mm (software even recommended 0.75mm) and then aligning the partial scans to one whole scan. Meshing was done at recommended settings and alignment to the coordinate system with Quicksurface.

## Scanning
Scanning was done in sPC connected mode (WiFi, with latest update 120FPS speed) at a moderate high point distance of 0.15mm (can go up/down to 0.05mm but at 0.15mm it already resulted in a 20M triangle file...) until target quality was reached. Keep an eye on ideal scan distance since it reduces with increasing point distance. When you are too far away scanning will be drastically slower compared to when you're in the ideal distance. 

## Post-Processing
When finishing the single scans it already creates a point cloud so I only had to align using automatic feature alignment (after deleting all unnecessary data from around the object). Afterwards I used Quicksurface to align the scan to the coordinate system and reduce the triangle count to a manageable 4M triangles.

I placed the casting on bed of marker cards and geometries so I can also capture the sides of the casting which I also use for aligning the two scans I created (top and bottom). The scan itself was performed with both cross and parallel line mode taking roughly 5min for scanning. No scan spray was used for scanning.

Parallax (Alister’s Ship) – Rigged | 4K Atlas + 2K Separated Textures

This is my restored and improved version of Alister’s ship, which I’ve named Parallax.

The original asset required significant cleanup and restructuring to be usable in modern workflows. I preserved the original textures as the visual foundation, then rebuilt the texture layout into a single 4K atlas for efficiency. For convenience, the atlas can also be separated into 2K textures without losing detail or UV accuracy.

Key Improvements:

Fully rigged with proper vertex groups

Original textures preserved and enhanced for clarity

Corrected structure and presentation for easier reuse in fan projects and renders

One of the biggest challenges was that the ship originally only had one seat and incomplete presentation in its extracted state. I spent a considerable amount of time refining proportions, alignment, and overall visual readability so it looks correct while still staying faithful to the original game asset

19th-century slate headstone of Patrick Madden (born c. 1829) who died aged 36 in 1865 & was buried in Nenagh graveyard, Kenyon Street, Co. Tipperary.  The inscription is framed within a border of semi-circles and double incised line running up along either side of the headstone.  The top of the headstone has a double-line inscised Latin Cross with expanded terminals, flanked on either site by an incised heart.  Above the hearts either side of the cross are lozenges framed within a decorative panel.  Two curvilinear lozenges are visible either side of the cross base.  Four leaf-cross withere side of the incised hearts.  Symbols on top of the headstone framed by border of semi-circles which may represent the folds of a a curtain pulled back to reveal the symbols.  Possible curvilinear sunburst quadrants in the corners of the border of the symbols and inscription panel. The horizontal lines visible on the inscription are ruling lines used by the stonecutter to set height, alignment, & spacing of the letters.

## Scanning
The motorcycle was scanned in markerless alser mode on the Rigil using 1mm resolution and feature tracking without connection to a PC. For scanning itself I didn't do any preparations like scan spray and focused on the both sides with one scan per side whilst ensuring enough overlap for easy alignment in later steps.  
While scanning the Rigil held roughly 20 FPS. Scanning itself took roughly 5 to 10min per side, so a a bit longer than in IR mode (was using 1.5mm there though). 

## Post-Processing
Post processing was done on my workstation and included generation of the point clouds, automatic feature alignment and subsequent meshing in recommended settings. Quicksurface was used for alignment to the coordinate system and reduction of the point cloud size. Since it came out quite large I reduced it to 4M so the scan could be uploaded to Sketchfab.

## Scanning
Scan was done in IR mode with 3mm resolution and large mode, Rigil was used standalone. For tracking only feature tracking was used (texture would have helped but the light was dim and flickery (fluorescent tubes be thanked) so no real help...). This created a bit of a challenge when scanning the tar large flat parts of the couch. The persian carpet would have provided enough texture but it couldn't be used for tracking due flickering of the light tubes. Scan itself took roughly 5min.

## Post-Processing
Just point cloud generation and meshing at recommended settings (meshing as semi-watertight) on my workstation (simply faster than on device). After meshing I did a quick texture optimization and alignment within Exscan Rigil.

The final result consists of two scans (top and bottom) to capture the whole armchair. Between the scans I had to turn the chair around so I made sure to capture all cushiony parts in the top scan so when they are deformed after turning I already captured them.

## Scanning
The scan was created in IR-mode with automatic exposure and geometry tracking. I created two scans: one of the whole tombstone in large scan mode and one detailed one of the head in normal scan mode. I started from the front and slowly moved around the part while keeping an eye on having enough overlap for tracking (rotating the scanner to reach in to the crevices works quite well to circumvent obstructions due to limited line of sight). While scanning the framerate was roughly 10 FPS with some highs to 15 and lows to 6 FPS (NIR mode still needs an update I guess, currently no marker scanning supported).

## Post-Processing
For post processing I first transferred the scan data from the P1 to my workstation. I then fused the whole tombstone scan at 1mm and the high detail at 0.5mm. Fusion already creates a mesh so no need to mesh a second time (only needed when merging multiple scans or when you need texture mapping). For alignment and cleanup of the base I used Quicksurface.

剑龙stegosaurus2.0

Photogrammetry reconstruction of The Three Fates Fountain located in St Stephen’s Green, Dublin.
The model was captured using image-based reconstruction and processed in RealityScan, followed by geometry cleanup, mesh optimization, and alignment in Blender.

Due to reconstruction issues with reflective water surfaces, an additional scan was used to replace and refine the fountain water geometry before final merging and decimation.

This model was produced as part of a virtual field trip assignment demonstrating capture, reconstruction, mesh editing, optimization, and real-time deployment preparation for Sketchfab and Unity.
