More Rendered Images 08/09/2024

Not that any of this particularly matters, here are some images rendered with Arnold that are going up on Instagram.

Pictures for Siggraph

 How can you go to Siggraph without bringing pictures?  Well you can't.  Here are a few rendered pictures and maybe I will do a few Midjourney pictures as well.  Csn you get which one is which?

More Rendering Tests II

Some random tests.   Tests to create complexity from simple procedural forms and working in the area of classical expressiveness (gestural rendering).  The process of doing computer graphics without clients (or where you are your own client) is so different and so much more rewarding.

More Rendering Tests

The following are more tests of various abstract creatures and rendering techniques.  

 

 

Three Test Images for the Dome in Arnold

draft

One image made with a fisheye lens whose field of view is 180 degrees, one whose fov is 270 and one whose fov is 360.  The "Arnold" watermark is there because I have a demo / unlicensed copy.

These images were fast to compute and trivial to technical direct.

Special thanks to the nice people at Solid Angle for helping me out.
 

The Mighty Sphere

About two years ago, I decided to learn NVIDIA's GPU programming environment, CUDA. I wrote a volume renderer in it which can render anything you want as long as it is a sphere.

The problem of course with volume rendering is getting data to render. Volume datasets are usually associated with scientific visualization and when you can get them at all they are not trivial to process. They are real data about real things and it requires serious work to make something of them.

So, for my tests I used normal 3D objects but made every vertex a sphere. It turned out pretty well. Here are two test images, one with glowy spheres and one with spheres that were more hardedged.

You get extra credit if you can figure out what they were originally.

Give up?  The one on the bottom is an upside down SR-71.   The one on top is something with a backbone, you can see the vertebrae clearly.  Dont remember what it was, though.
