Resolution: 720 x 576
Objects/Polygons: 2 / 3769
Render Time: 33s
Primary/Secondary Rays: 429147 / 836054
Speed: 39305 rays/s

Screenshots v0.8.3

Bigger Scene

Date: 2005/04/14
Resolution: 1000 x 1000
Objects/Polygons: 42 / 192619

Render Time: 3m 3s
Primary/Secondary Rays: 1000000 / 1368136
Speed: 12961 rays/s
Anti-aliasing: none
Aperture Samples: 1

Render Time: 1h 45m 47s
Primary/Secondary Rays: 30191798 / 42583255
Speed: 12663 rays/s
Anti-aliasing: Adaptive super-sampling
Aperture Samples: 26

Scene: 41 ships at sea
Details: 41 ships on bumpmapped water. In a grid but with random rotations. One light source. The first image uses no anti-aliasing and one aperture sample. The second uses adaptive supersampling and 26 samples for the aperture.

Instancing

Date: 2005/04/05
Resolution: 1024 x 768
Objects/Polygons: 6 / 23491
Render Time: 2m 27s
Primary/Secondary Rays: 871310 / 1113357
Speed: 13500 rays/s
Anti-aliasing: Adaptive super-sampling
Aperture Samples: 1

Scene: Five ships at sea
Details: Five galleon on bumpmapped water. One is sinking. Two light sources.

Screenshots v0.8.2

Glass

Date: 2005/03/26
Resolution: 400 x 300
Objects/Polygons: 3 / 3770
Render Time: 11s
Primary/Secondary Rays:
Speed: rays/s
Anti-aliasing: Adaptive super-sampling
Aperture Samples: 1

Scene: A noisy torus-knot
Details: The same scene as below but with a back wall and noise applied. Shows refraction through the glass (the animated version is better). Last shot before the refraction lighting model is changed to add extinction etc.

Iridescence & Object Bounding Trees

Date: 2005/03/24
Resolution: 720 x 576
Objects/Polygons: 2 / 3769
Render Time: 75s
Primary/Secondary Rays: 424126 / 655867
Speed: 14378rays/s
Anti-aliasing: Adaptive super-sampling
Aperture Samples: 1

Scene: A noisy torus-knot
Details: The same scene as below but with three white lights and a shader programmed to give iridesence, looking up the colour from a ramp. A similar scene before the bounding volume tree was added took over 30 minutes to render, this was reduced to around 26 seconds with the tree.

Screenshots v0.8

OBJ File Loading & Instancing

Date: 2005/03/21
Resolution: 720 x 576
Objects/Polygons: 2 / 3769
Render Time: 36m 48s
Primary/Secondary Rays: 427406 / 263862
Speed: 313rays/s
Anti-aliasing: Adaptive super-sampling
Aperture Samples: 1

Scene: A noisy torus-knot
Details: A large torus-knot with noise applied to the vertices before exporting. No bounding volume tree on the model itself so the rendering is very slow. Two light sources. A single model data set can be use multiple times.
