Mirror of SF Shrimp, with GTK1.x, FLTK2, Qt4 clients, didactic/historic purposes

Shrimp

The Shrimp RenderMan Shading Language shader building tool, that exposed RSL's functions as building blocks. In that regard it was more of a shader building tool than a shader network building tool.

This contains all the development history that was spread amongst the CVS, SVN and Mercurial branches, for the historical GTK 1.x application, FLTK2, and finally Qt4 GUI/frontend.

---

Why?

RSL was deprecated in the latest RenderMan versions, the code is provided as a learning/didactic resource. The latest version of PRman to support RSL was version 20.0. 3Delight version (up to) 12.5 is also supported.

Building

Unless you're into software archeology, the sanest choice is to just use Qt4:

qmake-qt4 shrimp.pro
make all

Using

As an example, using 3Delight, then make sure you have your 3Delight environment variables set.

export DELIGHT=/path/to/3delight
export LD_LIBRARY_PATH=${DELIGHT}/lib:${LD_LIBRARY_PATH}
export PATH=$PATH:${DELIGHT}/bin

and add

export DL_RESOURCES_PATH=/path/to/shrimp_repo/data/rib/scenes/archives
export DL_SHADERS_PATH=${HOME}/.shrimp/temp

Start the application, and off you go.

Need to auto handle quotation mark displaying and setting if block input is 'string'

Scene preferences not stored

Scene set and stored in preferences is not retained with restart in the scene field in the main UI.

1. Click 'Add Block' button
2. Add "Shader Functions" -> "Diffuse" -> "Diffuse"
3. Right click "Cdiff" input in newly created "Diffuse" block, click "Edit"
4. Clicking 'Color' and 'File' buttons in popup dialog do nothing
