RenderMonkeyâ„¢ Toolsuite
RenderMonkey is a suite of open, extensible shader development tools for both current and future hardware that allows programmers and artists to collaborate on creating realtime shader effects.
ATI showed these tools publicly for the first time at Siggraph 2002 in San Antonio, on the ATI booth and in a number of partner sessions.
A Beta version of the RenderMonkey IDE is currently available for free download to anyone interested in working with programmable graphics shaders.
Workspace:
Open Extensible Framework for integration of shader tool components
Data saved in an Open XML Shader Database
RenderMonkey provides an Integrated Development Environment for shaders
This allows Programmers and Artists to collaborate on creating compelling visual content
It provides an open/extensible shader delivery & integration mechanism
It provides a framework for future shader tools development
Integrated Preview:
Provides immediate visual feedback of effect under development
Simple/intuitive user Interface
Effects can be previewed on arbitrary geometry
For Programmers:
Modelled on Visual Studio GUI to provide an intuitive interface
Editors for Vertex and Pixel shaders
Syntax Coloring
Integrated support for Microsoft shader compiler
Support for DX8 (today), DX9 and OpenGL shader models (future)
For the Artist:
Artist friendly variable editors
Artist view of workspace
Allows only the artist editable parameters to be touched
Artist Editor
Groups variables into a single edit screen
Look and feel mimics popular Digital Content Creation packages
Example Workspaces:
A number of sample shader workspaces are provided as a starting point for shader developers. These include:
Bump Mapping
Metallic Effects
Terrain Effects
Non Photorealistic Effects
Simple Lighting Effects
Noise Effects - Fire, Clouds
Water Effects
