Generated HDR set (with backplates) for IBL / Image Based Lighting process walk through.

As a dual pair of images was taken, we can also use these as a photogrammetry pair.

Process involved:

  • White Balance marker placement
  • Spheron scans (two of)
  • Digital backplates (taken with full frame sensor Canon 5D) and measurement cube in situ
  • Post-Processing of raw Spheron (.SPH) files to crate Radiance files (.HDR) (using Spheron native Image Processing Engine)
  • White Balancing Backplates (using Adobe Photoshop)
  • Removing Lens Distortion (using Adobe Photoshop)
  • White Balancing Radiance / HDR file (using Adobe Photoshop)
  • Resizing down to 5K wide file (for initial render tests) (using Adobe Photoshop)

Taking time to compile…

Started three weeks ago, and slowly coming together.

Main considerations are:

  • navigation through materials
  • protecting materials (research based)
  • sections
  • standardizing page formats – within the chosen theme
  • sourcing data / images
  • becoming more proficient with WordPress

Key to both scaling and perspective matching, a ‘measurement cube’ is an essential component of the Image Based Lighting setup process.

Amazingly, they are very hard to find / purchase, so I decided to create my own.

In the past I have used a Gypsy 6 Motion Capture suit calibration cube  – which served the purpose, but also had following shortcomings:

  • Physical size was not ideal for IBL sets intended for larger asset renders
  • Color of cube made it had to see / work with
  • Bars very thin – making them hard to see.
  • It was part a system owned by my former employer in UK, so not available to me in USA.

Budget Alternative – Cardboard Board

In absence of above, I have used cardboard boxes, although this again has its limitations:

  • Not square
  • Cannot see through it
  • Harder to establish ‘perspective’ viewpoint

Resultant Images – Test Renders

My solution comprises:

  • 8 X 3D printed corners – using a MakerBot 3D printer
  • 12 X 2 foot PVC tubes (courtesy of The Home Depot)

Cube Measurements (in Millimetres, as working in Metric inside Maya)

  • Across Centers = 630 mm
  • Tube Diameter = 21 mm
  • Sphere Diameter = 50.8 mm

End result – a fairly lightweight, highly visible asset – total cost about $20
