Screenshots of Assassin’s Creed 4 Black flag

• I took some screenshots of Assassin's Creed 4 Black Flag at PC.

Dynamic global illumination

• I must confess that I have bought this game to see the effect of dynamic global illumination. :)
• So, I have tried to found the effect of the dynamic global illumination technique ("Deferred radiance transfer volumes") in this game.
• But I couldn't find a good scene yet. I guess, my graphics search skill is poor. :(
• If I find some good scenes, I will paste to this blog !

• By the way, the images below are captured from the tech video.

• I wrote some links about dynamic global illumination in AC4.

Local reflection

• In interior scene, local reflection is applied only to the floor.

• The reflection result lookup the rendered color buffer, so the reflection of the character is included.

• No wonder that if the objects goes outside the screen, the reflection of the objects disappears.

• I guess that the rendering resolution of local reflection is low, so the reflection effect is weaked to soften the artifacts.

Fading footsteps

Dynamic interaction with plants

Cubemap reflection at pond

• In the pond of the islands, traditonal cubemap reflection is used.
• So, the reflection result and the surrounding scene mismatches.

Planar reflection at ocean

• Planar reflection is used to realize the reflection of the ocean.
