</div></div>#### Frame Debugger

The CGI Studio Analyzer contains a Frame Debugger. This feature can be used to analyze the rendering process of [Candera](http://dev.doc.cgistudio.at/APILINK/namespace_candera.html "[DataBinding_RefTypeSample]") on a target device. It provides an overview about the composition of one frame (rendered nodes), shows detailed OpenGL information and adds the ability to capture the color, depth and stencil buffers.
