- I have uploaded a few archives from hobbes.lbl.gov's Radiance models
- and libraries. They should include README files explaining their
- contents and origins. They are all in Radiance format, which has
- the key distinction of being physically-based.
-
- I have just recently written a translator from Wavefront's .obj
- format into Radiance, but I currently have nothing to go from Radiance
- to any other format. Sorry about that.
-
- The renderer is free, however, from the above site.

- OBJECTS (gjward1.tar.Z and pdbourke.tar.Z)
-
- I have the following suggestions for object coordinates, which should
- be made more specific with overall dimensions in a comment at the top
- of each file:
-
- Furniture: Units = meters
- [The following is described looking from "back"]
- (0,0,0) located at bottom back left corner
- X-axis directed towards "right"
- Y-axis directed towards "front"
- Z-axis directed up
-
- Knick-knacks: Units = meters or centimeters
- Orient the same as furniture except (0,0,0) can be
- at center of rest point (ie. bottom) if object has
- high degree of radial symmetry (eg. a vase or cup).
-
- Fixtures: Units = meters
- [Present right-handed version only, ie. hinge
- on right means pull fixture towards you on left]
- (0,0,0) at lowest hinge or mount point if there is one,
- highest mount point if it is a ceiling fixture
- X-axis in plane of fixture, towards handle side if one
- Y-axis out of plane
- Z-axis up
-
- Buildings: Units = meters
- (0,0,0) located at the ground level of SW corner
- X-axis directed towards "East"
- Y-axis directed towards "North"
- Z-axis directed up
-
- Plants: Units = meters
- (0,0,0) located where ground meets plant (ie. the root)
- Y-axis directed "North" for phototropic plants
- Z-axis directed up
-
- People (standing): Units = meters
- (0,0,0) located at ground under center of gravity
- X-axis points to person's right
- Y-axis points in person's forward direction
- Z-axis directed up
-
- People (sitting): Units = meters
- (0,0,0) located at rump under center of gravity
- X-axis points to person's right
- Y-axis points in person's forward direction
- Z-axis directed up
-
- People (laying): Units = meters
- (0,0,0) located at back of the head
- X-axis points to person's right (left if prone)
- Y-axis points towards feet
- Z-axis directed up
-
- Animals (excl. people) Units = meters
- (0,0,0) located at rear (ground level if land animal)
- X-axis pointing to animal's right
- Y-axis to animals front
- Z-axis directed up
-
- Objects should be collected in compressed tar files, one such file per
- contributor. It would be too messy to have one tar file for each object,
- since each person might contribute several objects, and everyone has
- an object called "chair".

- MODELS
-
- This directory contains complete Radiance scene descriptions with
- the necessary makefiles for rebuilding the octrees and rendering
- the scene with rview from a good viewpoint. These models are
- stored as compressed tar files that unpack to a directory with
- all the required input and auxiliary files.
-
- Here is a list of models currently offered:
-
- bath.tar.Z - Modest bathroom model by Greg Ward
- conf.tar.Z - LBL conference room by Anat Grynberg and Greg Ward
- cubspace.tar.Z - Cubicle office space by Anat Grynberg and Greg Ward
- podlife.tar.Z - Whale sculpture by Cindy Larson and Greg Ward
- soda.tar.Z - Ice cream store by Greg Ward
- townhouse.tar.Z - Model of a townhouse by Paul Bourke
- virtual.tar.Z - Virtual light source example by Greg Ward
-
- If you are making a submission, please do what is necessary to make
- the first paragraph true. Please do not include any octrees or large
- images of your model, since they require too much storage space. You may
- follow the example in podlife.tar.Z.
