Fryrender is an unbiased physically correct commercial rendering engine suited for the architectural visualization community. We are testing it for possible inclusion within our rendering toolkit. www.fryrender.com

Osario Test Renders using Fryrender

This section shows various technical tests made using test scenes of the Osario. The test scene was created to give a base example of the general components of a typical scene: High-poly decimated mesh derived from scan data, flora, HDR sky, and various texture inputs. Currently this scene contains around 900,000 polys and the Osario wall maps are 2K each while the grass texture in front of the camera area up to the ruins is 4K. If decimated poly models are being used in the final render the final poly count will likely be an order of magnitude higher while the textures will be closer to 4K. While the still image fidelity and functionality of Fryrender is excellent (see their website for examples), we are mostly observing it's viability (render time and flickering artefacts) in dynamically moving camera situations.

render tests v01

Still render using predefined Fryrender shaders with custom textures. Mostly a test just to see if it would correctly output the geometry, UV's, and textures correctly from Maya(software). We are using a demo version at this point and we Photoshop'd out the 'Fryrender' logo to see the image more clearly. Subsequent images will have this logo appear randomly.

render tests v02

Low quality still render using modified diffuse shaders with additional plants and textures. There is actually grass geometry from Maya(software) PaintFX next to the ruins and the tree to break up the intersection of the ground plane but it is way too small to be seen. The modified diffuse shader is an initial attempt to control the BRDF curve on the limestone. The image is wildly out of focus in the foreground because Fryrender uses physically accurate cameras to render the scene and it turns out this scene is less than 1 meter long in Maya(software) world space.

render tests v03

Image

This image represents a completely rebuilt scene in Maya(software) with the Osario at it's exact dimensions in world space to alleviate the camera defocusing seen previously. We also introduced an animated camera in order to test a sequential render and added a simple bump into the grass to see how that would react. Render times were limited to 3 minutes/frame (rez 800x600) in order to see initial output.

This scene contains the addition of the Physical Sun feature in conjunction with image based lighting (IBL) in Fryrender. It is correlated to loosely be in the direction of the HDR sky image but cheated a bit to achieve more interesting lighting. Render quality was improved by limiting the renders to 8 passes/frame which turned out to be about 55 min/frame (rez 800x600) on a 32 bit dual core machine.

render tests v05

This scene contains the same lighting configuration as the previous test but several small changes were made. The BRDF curve on the limestone was modified to see it's effect and the bump was taken out of the grass completely. Subsurface scattering was also taken out of the tree leaves as it probably contributed to the high render times of the previous test. It now has a default diffuse shader with a base ramp color. Higher render quality (limit 2hrs/frame) was being tested at the final resolution (1920x1440) on a 64 bit quad core machine. INSIGHT purchased a license of Fryrender so we no longer have restrictions on size and are free of the randomly placed logo.
