Artist's Comments
About Us:
At the moment we are 28 developers / artists in our dev crew, especially 6 for laserscan, photogrammetry.
     We are searching and testing different ways for a photo-real CG artwork. Here we must distinguish
     the kind of the source objects (fruits, vegetables, technics, interior items and more). For the laserscan we are using
     different types of laser scanners. Artec Leo and/or Artec spider with a resolution from 0.2mm up to
     1 mm. The texture (Albedo) for such objects we make with a Nikon D 850, Canon EOS 5D Mark IV or 
     Canon 1 DX  Mark II. Since a few weeks we started with Substance Alechemist for the complete
     texture set like normal, roughness, ao and height maps. The complete Reconstruction in high detail
     we make in Reality Capture (laser point clouds and / or photogrammetry source files).

     Our goal is to reach a photo-real finish. One reason is also psychology! Here we distinguish the
     unconscious and the conscious part of a brain. The conscious (here the eyes) part of the brain realize 
     the artwork and send the information to the unconscious part. If the unconscious search now hundreds
     and thousands times /sec in the image for a kind of "yes I have seen this before .... or here is something
     which is wrong...). If we reach a quality where the unconscious part send the signal and say : this looks real, also
     i saw this exactly in the past....", than the brain get the signal : perhaps it is a photo or it is a part of something
     which i saw in the past somewhere (perhaps somewhere at the fruit stand, in the kitchen....)

About "Strawberries:"

Scene setup :

     At first we make some reference images with our Camera from the scene. In the case of the strawberry project

     we put the strawberries on a wooden ground in the nature. This is very important for the finished render and that we 

     have the same light and camera conditions. Second point : we make a 16k HDRI image from the setup so that

     we have the same light conditions. The albedo texture was produced in a tent. We build around such a scene a white

     tent and start to illuminate the tent from outside with different bright light sources. In the Strawberry project we used

     different "cold" light sources, warm light sources and some red led lights so that we have a uniform bright light

     inside the tent. Sometimes we make also a laser scan from the ground of the object (e.g. wooden ground, tables and more...)


     The laser-scan takes around 5 sec up to 120 - 180 seconds (dependent on the object) 

     For the texture we make 250-800 Photos. 


     Scene setup in Blender 3D 2.8. Here we combine now the environment light with the HDRI which me made

     from the scene. Starting texturing our objects with the textures which we made in Alchemist. Such objects have

     always a huge amount of polygons. It depend on the object and the complete scene. (from 100 MB up to more than 4 GB).

     Rendered in Cycles but also in Eevee we had in the past fantastic results.


     The Strawberries project was rendered on a Core i9 9980XE processor, 128 GB RAM and

     2 x GeForce RTX 2080 Ti with 22 GB.
