Physically Based Rendering by Gege
- 3. @agatestudio Physically Based Rendering • New method in producing 3D art • Based on a more realistic reasoning theory • We will discuss: – Basic theory – Marmoset Toolbag Demo – dDo workflow (if time permits)
- 5. @agatestudio Diffusion and Reflection • Usually known as “diffuse” and “specular” light.
- 7. @agatestudio 3 Diffuse Phenomenon Diffuse Translucent Transparent
- 8. @agatestudio Energy Conservation • Light leaving a surface can not be brighter than the lights that fell upon it.
- 9. @agatestudio Metal VS Insulator • Metals are more reflective than insulators – Metal: 60-90% – Insulator: 0-20% • Metal tints reflected color • Metal absorbs lights that penetrates
- 10. @agatestudio Fresnel • All smooth object will reflect perfectly on grazing angles.
- 11. @agatestudio Microsurface • Irregularity of object surface • Finer than 1 pixel, can not be described using normal map (sanely)
- 12. @agatestudio Energy Conservation • Rough surface = dim and spread reflection
- 13. @agatestudio Microsurface • Gloss directly affects the brightness of reflections
- 17. @agatestudio Microsurface / Smoothness / Gloss
- 18. @agatestudio Reflectivity • 3 different workflow: – Specular map – Metal map – IOR
- 19. @agatestudio Fresnel • Can not be controlled, but you should know what to expect
- 20. Thank You! ( Demo and FAQ while we’re on break! )
