Car render WIP

I have some fun working on shading. Work in progress

Capturing Reality

Quick testing of Capturing Reality. Works much better on plane surfaces then Photoscan, but not so well on objects. I tested it as limited trial, so cant play with real geometry after reconstruction.

Photogrammetry

Why not use video as source of photos?... Lets try!

High-contrast Computational Caustic Design (SIGGRAPH 2014)

Very interesting video with caustic - https://www.youtube.com/watch?v=R00IvqcI9jU

Unreal Engine 4 Car paint material update

Car paint shader with metallic micro flakes, made in Unreal Engine 4. Very realistic result :)

Unreal Engine 4 Car Paint and Carbon Fiber shaders

(work in progress) Car Paint and Carbon Fiber shaders in Unreal Engine 4.11.

Unreal Engine 4 Shader tests images

Some images of materials from previous posts

Unreal Engine 4 Car Paint shader WIP

Car Paint shader (work in progress) in Unreal Engine 4.

Unreal Engine 4 Iridescence, Think films shader

Created in HLSL and also in Unreal Engine material editor nodes. Also, worked on displacement and normals in this material.



With different settings

Unreal Engine 4 some shaders tests

Worked on Christmas Ball shader, simple test


Translated my RSL Beckmann shader to HLSL (roughness input is a noise texture)

Mudbox tips

Display a model without lights and shading
To turn on Flat Lighting do either of the following:
* From the main menu, select Display > Flat Lighting.
* Right-click an empty area of the 3D View and select Flat Lighting

Highlight problem areas on a mesh
To toggle the display of mesh error highlighting:
* Select Display > Mesh Errors from the main menu bar.

local webgl

python 3:
python -m SimpleHTTPServer

python 2:
python -m http.server 8000

in browser:
http://localhost:8000

import files dialog Maya (mel)

string $result[] = `fileDialog2 -fm 3 -ds 2 -cap "Choose Folder with Caches" -okc "Select"`;

$selected = `ls -sl`;

for ($node in $selected)
{
   string $geo[] = `select -r $node;`
   select -r $node;
   doImportCacheFile(($result[0] + "\\" + $node), "xmlcache", $geo[0], {});
}

3D Scans

Reconstructed model of 3D scan, base mesh created using Agisoft Photoscan. In general this program works very well, but some model was very challenging to fix errors. In this video I show model before and after I fixed and corrected issues. I created more than 300 model of photoreal 3D apparel and developed pipeline to automate some phases of 3D scan cleaning.
