-
- General info:
-
- torad.lsp
-
- Software extension for Autocad to export data to the RADIANCE light
- simulation package of the Lawrence Berkeley Laboratory.
-
- Makes complete translation of all hiding/shading entities from
- Autocad (and some more).
-
- Entities can be selected on screen for partial export.
-
- Entities will be sorted by one of the three criteria color, layer or
- insertion layer of blocks (toplayer) according to your choice.
- The sorting results in seperate files written for every layer or color.
- Floating layers and colors within blocks are fully supported.
-
- Other files created optionally can contain initial material definitions
- (all identical), a list of "!cat" commands to include all the
- information to make up a complete scene description, a setup of natural
- lighting, a view description and a makefile for automatic image creation.
-
- Only the entities that are visible (that is their layer is on and thawed)
- will be exported, even when nested in a selected block. This gives you
- another method of filtering elements of your drawing especially usefull
- when you want to update only part of a scene.
-
- The layername or color number will be part of each respective filename
- to make it an unique identifier.
-
- You have full control through a sreen menu section, a text dialog
- or even a interactive dialog box if you are running Autocad 12.
-
-
- Entities exported (by choice):
-
- Autocad entities: radiance objects:
-
- - 3dfaces - triangular or quadrilateral polygons.
- - extruded or flat traces - triangular and/or quadrilateral polygons.
- - extruded or flat solids - triangular and/or quadrilateral polygons.
- - extruded or flat circles - rings and quadrilateral polygons.
- - extruded arcs - quadrilateral polygons.
- - extruded lines - quadrilateral polygons.
- - extruded 2d-plines - quadrilateral polygons.
- - wide 2d-plines - multilateral polygons.
- - closed 2d-plines - multilateral polygons.
- - 3d-meshes - triangular or quadrilateral polygons.
- - polyfaces - triangular or quadrilateral polygons.
- - points - spheres or bubbles.
-
-
- torad.lsp is optimized for speed and memory usage as far as possible
- without loosing the functionality of sorting entities to seperate files.
- If you still consider it to be too slow, you will have to rewrite it
- in C (or pay me for doing so ;-).
-
- But still, it really works!
-
-
- the complete program consists of eight files (up to the moment):
-
- Program files:
- torad.lsp Main program source file.
- esample.lsp Entities sampling and conversion source file.
- vector.lsp Geometrical utilities source file.
- torad.dcl Dialog box definition file for Autocad 12.
- torad.mnu/x Menu file for setup with Autocad 10/11.
-
- Additional Files:
- torad.man User manual.
- torad.README This file.
-
- All these files are packaged in both a compressed tar file and a
- zip archieve to make them easily accessible for users of each unix
- and dos systems.
-

-
- "support"
- I expect the program and the manual to be self explanatory for users
- who have at least some experiance with either Autocad, Radiance or
- better both of them. If there still remain questions that cannot be
- answered neither through the manuals of Autocad, RADIANCE or torad.lsp
- nor by the local guru, you might try to reach me by mail under
- <mischler@arch.ethz.ch>.
- Be sure to notify me if you think you have found a bug in this program
- (there still might be some although thoroughly tested).
- It may happen that you will have to wait a few days for an answer since
- I am more like a guest at this site and therefore can not garantee
- to look into my mail daily.
