NVIDIA says the Official
for Cyberpunk 2077
shows off their ray tracing technology. They add that the upcoming
sci-fi RPG will also utilize NVIDIA DLSS 2.0. They offer the following details
on the game's ray tracing support:
Gamers can expect to experience the following ray-traced features in
Cyberpunk 2077 at launch:
- Ray-traced ambient occlusion - Ambient occlusion is a shading and
rendering technique used to calculate how exposed each point in a scene is
to ambient lighting. The result is a diffuse shading effect that darkens
enclosed and sheltered areas and enhances the rendered image's overall tone.
In Cyberpunk 2077, ray-traced ambient occlusion additionally can be used
with local lights to approximate local shadowing effects where shadows are
- Ray-traced diffuse illumination - This technique is used to
capture sky radiance as well as emissive lighting from various surfaces,
which is difficult to achieve with traditional rendering techniques.
- Ray-traced reflections - In Cyberpunk 2077, ray-traced
reflections are used on all surfaces and can trace ranges for up to several
kilometers. They are present on both opaque and transparent objects to
simulate the way light reflects from glossy and metal surfaces by tracing a
single bounce of reflection rays against the scene. This includes smooth
natural mirrors like window glass, but also rougher surfaces like brushed
metal. Unlike screen space techniques which can only reflect what’s on
screen, ray-traced reflections incorporate the entire scene around the
character, and can accurately represent objects outside the camera view or
facing away from the camera.
- Ray-traced shadows - Cyberpunk 2077 preview supports directional
shadows from the sun and the moon. These shadows aim to be physically
accurate and even account for light scattering from clouds. Shadows may be
enhanced in the final release to support other types of light sources where
it is needed.
