Member Function Documentation

bool eqPixelBench::Channel::configExit ( )
protectedvirtual

Exit this channel.

Version
1.0

Reimplemented from eq::Channel.

Definition at line 77 of file eqPixelBench/channel.cpp.

References eq::Channel::configExit(), and eq::Frame::getFrameData().

+ Here is the call graph for this function:

void eqPixelBench::Channel::frameDraw ( const eq::uint128_t &  frameID)
protectedvirtual

Draw the scene.

Called 0 to n times during one frame.

Parameters
frameIDthe per-frame identifier.
Version
