Camera Inferno is a tool to generate burn-in text for Pre-Visualisation (PreVis), Technical-Visualisation (TechVis) and Camera Layout. The project name "camera inferno" was coined by Alex Jeremy, because the tool "burns-in" text into renders.
Camera Inferno creates a custom "locator" node that connects to a camera frustum and draws the visualisation text the real-time Maya™ Viewport. Camera Inferno is written entirely in Python, using the Maya™ Python API bindings for the dcVelocity node. The reason for using Python is to avoid the requirement of C++ compilation and ABI compatibility to allow the easiest installation possible.
